Proxy Statement

General

The annual meeting of the stockholders of Terra Industries Inc. will be held at the Sioux City Convention Center, 801 Fourth Street, Sioux City, Iowa 51101, on Tuesday, May 2, 2006, at 9:00 a.m.

The mailing address of Terra’s principal executive offices is Terra Centre, 600 Fourth Street, P.O. Box 6000, Sioux City, Iowa 51102-6000. This proxy statement and the accompanying proxy are first being sent or given to stockholders on or about March 20, 2006.

Terra’s board of directors solicits the accompanying proxy. The stockholder may revoke it at any time before it is voted at the annual meeting by giving written notice to the corporate secretary. This proxy, if properly executed, duly returned and not revoked, will be voted for the election of directors, except to the extent the stockholder withholds voting authority. Such proxy will also be voted on the other matters described in this proxy statement, in accordance with the instructions in the proxy. The board of directors is not aware at this date of any matter proposed to be presented at the annual meeting other than the election of directors and the ratification of the audit committee’s selection of independent accountants. The persons named in the accompanying proxy will have discretionary authority to vote on any other matter that is properly presented at the meeting, according to their best judgment. A stockholder’s presence at the annual meeting does not of itself revoke the proxy.

Securities Entitled to Vote

The only securities eligible to be voted at the annual meeting are Terra common shares. Only holders of common shares at the close of business on the record date, March 1, 2006, are entitled to vote. Each common share represents one vote, and all shares vote together as a single class. There were 95,168,174 common shares issued and outstanding on March 1, 2006.

Vote Required

Stockholders are entitled to cast one vote for each director nominated to the board of directors for each common share held on the record date. Cumulative voting is not permitted. Stockholders are also entitled to one vote per common share on each other matter voted upon at the annual meeting. To be elected, a director-nominee must receive more than half the votes present at the meeting for purposes of a quorum in person or by proxy and actually cast in the election of directors. Common shares of stockholders abstaining from voting, but otherwise present at the meeting in person or by proxy, will be included with broker non-votes and voted shares in determining the number of shares present at the meeting. Such abstaining shares and broker non-votes, however, will not be counted as a vote for or against any director-nominee.

The proposal to ratify the audit committee’s selection of independent accountants must receive a majority of votes present at the meeting for purposes of a quorum in person or by proxy and actually cast to be ratified. Common shares of stockholders abstaining from voting, but otherwise present at the meeting in person or by proxy, will be included with broker non-votes and voted shares in determining the number of shares present at the meeting. Such abstaining shares and broker non-votes, however, will not be counted as a vote for or against the selection of independent accountants.

Proposal 1: Election of Directors

Election of Directors

The board of directors adopted a classified board in accordance with Maryland law in early 2005. Following the adoption of the classified board, the directors were divided into three classes and assigned the terms of office required by Maryland law. The term of office of the two directors assigned to Class II expires at this meeting, and such two directors are nominated for election at this annual meeting to serve for three-year terms until the annual meeting in 2009 and until their successors are elected and qualify. As provided by Maryland law, the terms of office of the two directors assigned to Class I continue until the annual meeting in 2008, and the terms of office of the two directors assigned to Class III continue until the annual meeting in 2007, and in each case until their successors are elected and qualify. Each class of directors will be elected to serve for three-year terms. The directors in each Class are set forth below. The affirmative vote of more than half the votes present at the annual meeting eligible to be cast for a director-nominee and actually cast in the election of directors is required for election to the board. Unless otherwise indicated, proxies in the accompanying form will be voted for the nominees named below or for any successor nominee designated by the board. Such a successor nominee would be designated only in the unlikely event that a nominee named below becomes unable or unwilling to serve as a director before the election. All of the nominees named below are incumbent directors. Set forth below opposite the name and age of each nominee for Class II director, and for the Class I and Class III directors whose terms are continuing, are his or her present positions and offices with Terra, his or her principal occupations during the past five years, and the year in which he or she was first elected a director.

Several directors are also on the boards of directors of other companies subject to the reporting requirements of the U.S. federal securities laws. Mr. Bennett is a director of Alliant Energy and Terra Nitrogen GP Inc., the General Partner of Terra Nitrogen Company, L.P.; Mr. Fraser is a director of Forest Oil Corporation and Smith International, Inc.; Ms. Hesse is a director of Pinnacle West Capital Corporation, Arizona Public Service, Enbridge Energy Partners, L.P. and Enbridge Energy Management, L.L.C.; Mr. Slack is a director of Engelhard Corporation and Mwana (plc); and Mr. Janson is a director of Tembec Industries Inc., ATS Automation Tooling System and TK Shipping Corporation.

Corporate Governance

General

Terra strives to uphold the highest standards of ethical conduct, to follow corporate governance best practices, to report accurately and transparently, and to fully comply with the laws, rules and regulations that govern Terra’s business.

Our board of directors currently consists of six members. In accordance with our Corporate Governance Guidelines, Terra’s board has affirmatively determined that David E. Fisher, Dod A. Fraser, Martha O. Hesse, Peter S. Janson and Henry R. Slack each meet the criteria for independence required by the New York Stock Exchange (“NYSE”) listing standards. The board’s independence determination was based on information provided by our directors and discussions among our officers and directors. The nominating and corporate governance committee reviews and designates director-nominees in accordance with the policies and principles of its charter and the Corporate Governance Guidelines.

Terra has structured its board of directors to provide separate positions for a non-executive chairman of the board and a chief executive officer. The board plans to maintain these responsibilities as separate positions.

During 2005, in accordance with the Corporate Governance Guidelines, non-management directors met at regularly scheduled executive sessions of the board without management and the independent directors met in executive session. The chairman of the board, Henry R. Slack, presided at all executive sessions of the board, which are held at each of our board meetings.

The board currently has three committees—audit, compensation, and nominating and corporate governance. A description of each committee and its function appears in the “Board of Directors and Committees” section of this proxy statement under the heading “Board Committees.” The audit, compensation, and nominating and corporate governance committees are each composed solely of independent directors as required by the NYSE listing standards. In addition, the members of the audit committee meet the criteria for independence required by the Sarbanes-Oxley Act of 2002. Each committee has its own charter setting forth the qualifications for membership and the committee’s purposes, goals and responsibilities. Each of these committees has the power to hire independent legal, financial or other advisors it deems necessary, without consulting or obtaining the advance approval of any Terra officer.

The board has also adopted a Code of Ethics and Standards of Business Conduct, which outlines the principles, policies and laws that govern Terra’s activities and which serve as a tool for professional conduct in the workplace. The Code of Ethics and Standards of Business Conduct applies to Terra’s principal executive officer and principal financial officer and also includes all other officers, directors and employees.

Current versions of Terra’s Corporate Governance Guidelines, Code of Ethics and Standards of Business Conduct and committee charters, can be found in the “Investor Information” section of Terra’s website at www.terraindustries.com, and are available in print to any shareholder upon request.

Board of Directors and Committees

Board Committees

Audit Committee. The audit committee met seven times in 2005 and is currently composed of Mr. Fisher (Chairman), Ms. Hesse and Mr. Janson. The committee is composed entirely of non-employee directors, each of whom meets the “independence” requirements of the NYSE listing standards and the Sarbanes-Oxley Act of 2002. In accordance with Terra’s audit committee charter, all members of the committee are financially literate and the board of directors has determined that Mr. Fisher meets the requirements to be named “audit committee financial expert” as the term has been defined by the SEC rules implementing Section 407 of the Sarbanes-Oxley Act of 2002. The audit committee charter, which was amended on December 2, 2003, was reviewed at the February 14, 2006 meeting and is available on Terra’s website as set out in the Corporate Governance section above.

The audit committee reviews Terra’s procedures for reporting financial information to the public. The audit committee also reviews Terra’s internal audits, reports and related recommendations. Its members are directly responsible for Terra’s independent auditor and have the sole authority to appoint or replace the independent auditor. The committee reviews the scope of the annual audit. The committee also reviews related reports and recommendations and preapproves any non-audit services provided by such firm. In addition, the committee maintains, through regularly scheduled meetings, open lines of communication between the board of directors and Terra’s financial management, internal auditors and independent auditor. See the “Audit Committee Report” below.

Compensation Committee. The compensation committee met three times in 2005 and is currently composed of Messrs. Fraser (Chairman), Fisher and Janson. Each of the members of the committee meets the “independence” requirements under the NYSE listing standards. The committee’s functions include recommending to the board of directors the appointment of Terra executive officers and establishing the compensation to be paid to such individuals. The committee also administers certain employee benefit plans, establishes and, in consultation with management, administers compensation guidelines and personnel policies. See the “Report on Executive Compensation” below. The compensation committee charter was adopted on December 2, 2003, was reviewed at the February 14, 2006 meeting, and is available on Terra’s website as set out in the Corporate Governance section above.

Nominating and Corporate Governance Committee. The nominating and corporate governance committee met three times in 2005. It is currently composed of Ms. Hesse (Chairman), Mr. Fraser and Mr. Slack. Each of the members of the committee meets the “independence” requirements under the NYSE listing standards. The committee’s functions include helping the board fulfill its responsibilities to stockholders by shaping the company’s corporate governance and enhancing the quality and independence of the board nominees. In addition, the committee identifies and reviews qualifications of potential Terra director candidates and makes recommendations to the board for nomination or election. Nominees for director are selected on the basis of broad experience, wisdom, integrity, ability to make independent analytical inquiries, understanding of Terra’s business environment, and willingness to devote adequate time and energy to board duties. The board considers directors of diverse backgrounds, in terms of both the individuals involved and their various experiences and areas of expertise. Each board member must ensure that future commitments (including commitments to serve on boards of other companies) do not materially interfere with the member’s service as a Terra director. The nominating and corporate governance committee charter was adopted on December 2, 2003, was reviewed at the February 14, 2006 meeting, and is available on Terra’s website as set out in the Corporate Governance section above.

6

The nominating and corporate governance committee charter also provides that the committee will review candidates who have been recommended by shareholders but the committee has not established formal procedures to bring such nominees before them. Any such nominations to the nominating and corporate governance committee can be communicated to the board as set out in the Corporate Governance section of this proxy statement under the heading “Communication.”

The board of directors establishes special board committees from time to time, determining such committees’ specific functions as they are established. The board and its committees occasionally take action by unanimous written consent in lieu of a meeting.

Meetings of the Board

The board of directors held four regular meetings and two special meetings in 2005. Each director attended at least 75 percent of the total meetings of the board and of board committees of which he or she was a member.

Director Compensation

In May 2003, the board of directors voted to compensate non-employee directors with a mix of shares and cash. Under this policy, in 2005, Mr. Slack, Chairman of the Board, was granted 15,000 restricted shares (an annual award) and an annual cash retainer of $100,000 (payable quarterly). The other non-employee directors each received an annual restricted share grant of 10,000 shares, an annual retainer of $27,500 (payable quarterly) and meeting fees of $1,250 per meeting attended. Mr. Fisher received an additional cash retainer of $10,000 (payable quarterly) for serving as chairman of the audit committee. Ms. Hesse, chairman of the nominating and corporate governance committee, and Mr. Fraser, chairman of the compensation committee, each received an additional annual retainer of $4,000 (payable quarterly) for serving as committee chairs.

Compensation Committee Interlocks and Insider Participation

The compensation committee is composed of the directors named as signatories to the “Report on Executive Compensation” below. No director has any direct or indirect material interest in or relationship with Terra other than shareholdings as discussed above and as related to his or her position as a director, except as described under the caption “Certain Relationships and Related Transactions.” During 2005, no officer or other employee of Terra served on the board of directors of any other entity, where any officer or director of such entity also served on Terra’s board.

1/

Each director or executive officer has sole voting and investment power over the shares shown as beneficially owned. Each director and executive officer individually and beneficially owned less than one percent, and the directors and executive officers as a group owned 2.7% of Terra’s issued and outstanding common shares. These share numbers include ownership of restricted common shares, which is subject to certain vesting conditions, and shares held under Terra’s Employees’ Savings and Investment Plan.

The shares shown above also include shares acquirable pursuant to stock options, which are currently exercisable. Upon such exercise, the option holders would acquire shares as follows: Mr. Bennett (136,000); Mr. Fisher (18,000); Mr. Giesler (6,300); Mr. Kalafut (18,700); Mr. Meyer (100,000); Mr. Rosenbury (90,000); Mr. Slack (20,000); and all directors and executive officers as a group (421,100). Until the options are exercised, these individuals will neither have voting nor investment power over the underlying common shares but only have the right to acquire beneficial ownership of the shares through exercise of their respective options.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires Terra’s executive officers, directors and beneficial owners of more than 10 percent of Terra’s common shares to file initial reports of beneficial ownership and reports of changes in beneficial ownership of the shares with the SEC and the NYSE. Executive officers and directors are required by SEC regulations to furnish Terra with copies of all Section 16(a) reports they file. All of Terra’s executive officers, directors and beneficial owners of more than 10 percent of Terra’s common shares have filed all reports required under Section 16(a) during and with respect to 2005 in a timely manner, except Peter S. Janson who filed one Form 4 late. This conclusion is based solely on a review of the copies of such filings furnished to Terra and of written representations from Terra’s executive officers and directors.

Average Compensation (as defined under the Retirement Plan) as of December 31, 2005 for Mr. Bennett was $462,462; for Mr. Giesler $154,307; for Mr. Kalafut $217,799; and for Mr. Meyer $324,331. The estimated credited years of service under the Retirement Plan for each such officer was as follows: Mr. Bennett — 32; Mr. Giesler — 18; Mr. Kalafut — 16; and Mr. Meyer — 23.

“Compensation” under the Retirement Plan includes the total salary and wages paid to a participant, including bonuses through 2003, overtime, commissions and elective contributions made by Terra on behalf of the participant pursuant to Internal Revenue Code (the “Code”) sections 401(k) or 125. Covered earnings are limited by Section 401(a)(17) of the Code to $210,000 in 2005. The above benefits are subject to the limitations of Section 415 of the Code, which provides for a maximum annual payment of approximately $170,000 in 2005. Under the Excess Benefit Plan, however, Terra will supplement those benefits so that the amount the participant will receive will be equal to the amount that would have been received under the Retirement Plan but for such limitations. “Compensation” under the Excess Benefit Plan also includes amounts deferred under the Supplemental Deferred Compensation Plan.

14

Employee Contracts, Termination of Employment and Change of Control Arrangements

Terra’s Chief Executive Officer and each of the other named executive officers are party with Terra to an executive retention agreement. Each such agreement provides the executive with certain benefits if his employment is terminated under specified conditions. To receive benefits, the executive must be terminated within two years of a change of control (as defined in the agreement) of Terra. In addition, such termination must be made either by Terra or a successor entity without cause, or by the executive for good reason.

Benefits for Messrs. Bennett, Meyer, Rosenbury, Giesler and Kalafut under the executive retention agreements include (a) continuation of base salary and bonus for two years; (b) continuation of medical and dental benefits for two years; (c) payment of accrued but unpaid compensation; (d) automatic vesting in Terra’s Excess Benefit Plan with an addition of two years to the credited service level and the age of the participant for purposes of computing the accrued benefits under the Excess Benefit Plan; and (e) certain outplacement services. Such benefits are in lieu of any other severance benefits that may otherwise be payable. Compensation earned from other employment shall not reduce the amounts otherwise payable by Terra. Terra also agreed to reimburse each such officer on an after-tax basis for any excise tax incurred as a result of the “excess parachute payment” provisions of the Internal Revenue Code.

Performance Graph

The SEC requires that a comparative performance graph be included with this proxy statement. A line-graph presentation is required, comparing cumulative, indexed, five-year shareholder returns on specified, hypothetical investments. These investments must include the S&P 500 Stock Index and either a nationally recognized industry standard or an index of peer companies selected by Terra.

Terra has for some years chosen to use a self-selected industry peer group. The peer group used includes companies with market caps roughly similar to Terra’s and who manufacture commodity chemicals, including chemicals other than methanol and nitrogen fertilizers. The Industry Peer Group consists of Agrium, Inc.; Celanese AG; Cytec Industries, Inc.; Georgia Gulf Corporation; Lyondell Chemical Company; Methanex Corporation; Millenium Chemicals Inc.; Mosaic; NOVA Chemicals Corp.; Potash Corporation of Saskatchewan Inc.; Terra Nitrogen Company, L.P.; and Yara North America, Inc.

Compensation Committee Report

Report on Executive Compensation

General Policy

The compensation committee assists the Board in fulfilling its responsibility to stockholders by taking a leadership role in the design and administration of executive compensation programs, the annual evaluation of the performance of the CEO and senior management.

In 2005, the committee reviewed and restructured Terra’s executive compensation programs with the assistance of an independent consultant. The objectives were to structure the programs to:

1.	provide compensation and retention incentives that are competitive with companies of similar size and in similar businesses;
2.	limit Terra’s fixed cash obligations during cyclical downturns yet provide more generous cash compensation when the business cycle is favorable; and
3.	provide long-term incentives that are tied to shareholder returns and returns on invested capital.

The three elements of Terra’s executive compensation program are base salary, annual cash incentive awards and long-term incentive awards. Annual incentive awards are made under Terra’s Incentive Award Program for Officers and Key Employees (the “Key Executive Plan”). Long-term incentive compensation may consist of stock options, performance shares, restricted shares or other award opportunities offered under Terra’s shareholder-approved stock incentive plan (the “Long Term Plan”). In each case and in the aggregate, the compensation of Terra executive officers is compared with survey data compiled by the compensation committee’s independent consultant. The survey includes both chemical and general industry companies. The independent consultant adjusts survey information to arrive at market data comparable to Terra’s size.

The Internal Revenue Code limits the ability of Terra to deduct from its taxable income certain compensation paid to any executive in excess of $1 million. In the event compensation for any Terra executive exceeds this $1 million threshold, the compensation committee will balance the benefits of tax deductibility with its responsibility to retain and motivate executives with competitive compensation programs.

Base Salary

Terra’s compensation philosophy is to target its executives’ base salaries at approximately the 25^th percentile of comparable market data. This philosophy reflects Terra’s desire to minimize fixed costs because of the volatile nature of the nitrogen products industry.

Changes in the base salaries of executive officers, other than Mr. Bennett, are reviewed by the compensation committee annually with Mr. Bennett and the Senior Vice President and Chief Administrative Officer and are largely based on the officer’s performance and contribution to Terra and on comparable market data. The committee determines Mr. Bennett’s base salary as described below.

17

Annual Incentive Awards

Terra’s compensation philosophy is to provide its executives’ annual cash incentive awards that vary depending on pre-established corporate and individual goals. If the company and the executive meet their target objectives, the award is targeted to provide total cash compensation between approximately the 25^th and the 50^th percentile of comparable market data. If the goals are exceeded, the total cash compensation may exceed the 50^th percentile. If the goals are not met, annual cash incentive awards are not paid, although the committee has the right to make discretionary awards in exceptional circumstances.

In making annual awards, in the first quarter of each year, the committee approves an incentive pool that is the sum of specified target amounts for each participant. The target amounts for 2005 were generally 15% to 40% of a participant’s base salary except for Mr. Bennett, whose target amount was 70% of base salary. The target amounts for 2006 are generally 15% to 60% of the participant’s base salary, except for Mr. Bennett whose target amount is 115% of his base salary.

The incentive pool is funded depending on company performance. In 2005, the funding formula was: 50% if Terra achieved $30 million in net income, excluding the net income effects of the early retirement of debt and valuation of warrants, plus 1% for each additional $0.5 million in net income up to 200%. Thus, had Terra earned $105 million, the incentive pool would have been funded at 200% of target. Depending on an executive’s success in meeting his or her personal goals, individual awards are more or less than the funding percentage times their target award.

In 2005, Terra’s financial performance resulted in a 66% funding level resulting in an aggregate annual cash incentive pool of $1.1 million. In 2005, 40 executives, in addition to Mr. Bennett, participated in the Key Executive Plan.

Long Term Incentive Awards

The objectives of Terra’s long term incentive awards are to provide incentives to increase the return on capital employed to levels above the cost of capital on a sustainable basis; to provide incentives to increase stockholder returns over the long term; and to assist in executive retention. The Long Term Plan is intended, together with an executive’s base salary and annual cash incentives, to provide total compensation in excess of the 50^th percentile of comparable market data when performance targets required for the maximum award are achieved.

Under Terra’s Long Term Plan, the company makes two types of stock grants to its eleven most senior executives: (i) restricted shares and (ii) performance shares. In addition, the company grants phantom shares and phantom performance shares to 42 additional key employees that provide substantially equivalent incentives in the form of cash payments.

The restricted shares vest three years after the grant date, or upon a change in control. The performance shares are awarded three years after the grant date at between 0% and 200% of the number of shares granted based on Terra’s annualized average return on capital employed (“ROCE”) for the three year period. ROCE is defined as average annual income from operations less 35% for normal income tax expense divided by average capital employed (common and preferred stockholders equity plus short and long-term debt, deferred income taxes and minority interest, less cash). The award percentage is determined by the following formula:

a. If Terra’s annualized average ROCE for the period is less than 4%, no performance shares will be awarded.

18

b.	If Terra’s annualized average ROCE for the period is between 4% and 9%, 1% of the performance shares granted will be awarded for each 0.05% annualized average ROCE exceeds 4%.
c.	If Terra’s annualized average ROCE for the period exceeds 9%, 1% of the performance shares will also be awarded for each 0.025% annualized average ROCE exceeds 9% with the total number of performance shares awarded not exceeding 200% of the number granted.

The committee has set an annual long-term award target amount for each executive. In 2005, the target amounts were generally 90% to 140% of base salary, except for Mr. Bennett whose target amount was 310% of base salary. The number of shares awarded is determined by dividing the target amount by the then current share price. All executives receive one-half of their target amount in restricted shares and one half in performance shares, with the exception of Mr. Bennett who receives one-third in restricted shares and two-thirds in performance shares.

Pursuant to the Long Term Plan, in 2005, the committee granted 226,000 restricted shares and 298,000 performance shares. In addition, the committee granted 121,700 phantom shares and 56,300 phantom performance shares.

CEO Compensation

Base Salary. In determining Mr. Bennett’s base salary, the compensation committee considers several factors. These factors include salaries for comparable positions in the consultant’s survey data.

Annual Incentive Awards. Mr. Bennett’s 2005 annual incentive award target amount under the Key Executive Plan was 70% of base salary. Mr. Bennett was awarded $200,000 of incentive compensation for his 2005 performance. This award was based on Terra’s 2005 net income. Mr. Bennett received a $500,000 bonus for 2004 and no bonus for 2003, 2002 or 2001.

Long Term Incentive Awards. The compensation committee made a long-term incentive award to Mr. Bennett in July 2005. Several factors were considered in making this award, including the value of awards typically given chief executive officers in the consultant’s survey data. As a result, Mr. Bennett was granted 54,000 restricted shares and 126,000 performance shares. These shares will be awarded as described in the Long Term Incentive Awards section above.

Conclusion

The committee believes that the company’s executive compensation programs effectively tie executive compensation to the performance of the company and to shareholder value.

Audit Committee Report

The responsibilities of the audit committee, which are set forth in the audit committee charter adopted by the board of directors, include providing oversight to Terra’s financial reporting process through periodic meetings with Terra’s independent auditors, internal auditors and management to review accounting, auditing, internal controls and financial reporting matters. Terra management is responsible for the preparation and integrity of the financial reporting information and related systems of internal controls. The audit committee, in carrying out its role, relies on Terra’s senior management, including its senior financial management, its internal audit function, and its independent auditors.

The audit committee appointed Deloitte & Touche LLP as independent accountants for Terra for the fiscal year 2006 and recommends that shareholders vote in favor of “Proposal 2: Ratification of Selection of Independent Accountants” below.

We have reviewed and discussed with senior management Terra’s audited financial statements included in the 2005 Annual Report to Shareholders. Management has confirmed to us that the data in such financial statements (i) has been prepared with integrity and objectivity and is management’s responsibility, and (ii) has been prepared in conformity with generally accepted accounting principles.

We have discussed with Deloitte & Touche LLP, Terra’s independent auditors, the matters required to be discussed by the Statement of Audit Standard No. 61 (“SAS 61”) Communications with Audit Committees. SAS 61 requires Terra’s independent auditors to provide us with additional information regarding the scope and results of their audit of Terra’s financial statements, including with respect to (i) their responsibility under generally accepted auditing standards, (ii) significant accounting policies, (iii) management judgments and estimates, (iv) any significant audit adjustments, (v) any disagreements with management, and (vi) any difficulties encountered in performing the audit.

We have received from Deloitte & Touche a letter providing the disclosures required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) with respect to any relationships between Deloitte & Touche and Terra that in their professional judgment may reasonably be thought to bear on independence. Deloitte & Touche has discussed its independence with us, and has confirmed in such letter that, in its professional judgment, it is independent of Terra within the meaning of the federal securities laws. Deloitte & Touche have also discussed with us its findings related to its review of Terra’s internal control procedures as required by Section 404 of the Sarbanes-Oxley Act.

Based on the review and discussions described above with respect to Terra’s audited financial statements included in Terra’s 2005 Annual Report to Stockholders, we have recommended to the board of directors that such financial statements be included in Terra’s Annual Report on Form 10-K for filing with the SEC.

The audit committee has a policy concerning the approval of audit and non-audit services to be provided by Terra’s independent auditors. A copy of this policy can be found in Terra’s Audit Committee Charter on our website at www.terraindustries.com in the Investor Information section, Charters and Guidelines. The policy requires that all services provided by Terra’s independent auditors to Terra, including audit services and permitted audit-related and non-audit related services, be pre-approved by the audit committee.

20

In giving our recommendation to the board of directors, we have relied on (i) management’s representation that the data in such financial statements has been prepared with integrity and objectivity and in conformity with generally accepted accounting principles, and (ii) the report of Terra’s independent auditors with respect to such financial statements.

Proposal 2: Ratification of Selection of Independent Accountants

The board of directors recommends that the stockholders ratify the audit committee’s selection of Deloitte & Touche LLP as independent accountants for Terra for the fiscal year 2006.

It is expected that members of Deloitte & Touche will attend the annual meeting to make a statement if they desire to do so and to respond to any appropriate questions that may be asked by stockholders.

Principal Accountant Audit Fees and Service Fees

The table below describes fees for professional audit services rendered by Deloitte & Touche, Terra’s principal accountant, for the audit of Terra’s annual financial statements for the years ended December 31, 2005 and December 31, 2004 and fees billed for other services rendered by Deloitte & Touche during those periods.

Type of Fee	2005		2004
Audit Fees 1/	$	1,507,330	$	1,851,546
Audit Related Fees 2/		129,148		86,315

Tax Fees 3/		315,855		330,626
All Other Fees		0		0
Total	$	1,952,333	$	2,268,487

1/	Audit Fees, including those for statutory audits, include the aggregate fees paid by Terra during the fiscal year indicated for professional services rendered by Deloitte for the audit of Terra’s annual financial statements and review of financial statements included in Terra’s Form 10-Qs
2/	Audit Related Fees include the aggregate fees paid related to the audit of the Company’s retirement, savings and investment plans.
3/	Tax Fees include the aggregate fees paid by Terra during the fiscal year indicated for professional services rendered by the principal accountant for tax compliance, tax advice and tax planning.

The audit committee has advised Terra’s board of directors that it has determined that the non-audit services rendered by Terra’s independent auditors during Terra’s most recent fiscal year are compatible with maintaining such auditors’ independence.

The board of directors intends to introduce at the annual meeting the following resolution:

RESOLVED, that selection by the audit committee of Deloitte & Touche LLP as independent accountants for the Corporation for the year 2006 be, and it hereby is, ratified.

To ratify the audit committee’s selection of independent accountants, over half of the votes cast “for” or “against” such ratification must be cast “for.” Abstentions and broker non-votes will not be counted as a vote with respect to this proposal.

The board of directors recommends that you vote FOR the ratification of the audit committee’s selection of independent accountants.

22
