SCHEDULE 13D

Page 3 of 8 Pages

This Schedule 13D is filed by Jonathan J. Ledecky (“Ledecky”) with respect to ownership of the common stock, par value $0.0001 per share (“Common Stock”), of Cullen Agricultural Holding Corp., a Delaware corporation (the “Issuer”).

The percentage of beneficial ownership reflected in this Schedule 13D is based upon 19,247,311 shares of Common Stock outstanding as of October 22, 2009.

Item 1. Security and Issuer.

The class of equity securities to which this Schedule 13D relates is the Common Stock of the Issuer. The Issuer’s principal executive offices are located at 22 Barnett Shoals Road, Watkinsville, Georgia 30677.

Item 2. Identity and Background.

Ledecky’s business address is 970 West Broadway, PMB 402, Jackson, Wyoming 83001. Ledecky was previously the President and Secretary of Triplecrown Acquisition Corp. (“Triplecrown”), the Issuer’s predecessor.

Ledecky has not, during the past five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

Ledecky has not, during the past five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Ledecky is a citizen of the United States.

Item 3. Sources of Funds.

In June 2007, in connection with its formation, Triplecrown sold 11,500,000 shares of its common stock (“Initial Shares”) to its founders at a purchase price of approximately $0.002 per share. Ledecky purchased 6,030,000 of such shares at such time for aggregate purchase price of approximately $12,060 and Hat Tricks LLC, an entity owned and controlled by Ledecky, purchased 600,000 of such shares at such time for an aggregate purchase price of approximately $1,200. Each of Ledecky and Hat Tricks LLC used its working capital for such purchase.

In September 2007, Triplecrown’s board of directors authorized a dividend to the founders of one warrant to purchase one share of Triplecrown’s common stock for each outstanding share of Triplecrown’s common stock held by such founder (“Initial Warrants”). Accordingly, Ledecky acquired 6,030,000 of such Initial Warrants and Hat Tricks LLC acquired 600,000 of such Initial Warrants at such time. No funds were expended to acquire such warrants.

SCHEDULE 13D

Page 4 of 8 Pages

On October 25, 2007, simultaneously with its initial public offering, Triplecrown sold 5,000,000 warrants, each to purchase one share of Triplecrown’s common stock, to certain of its initial stockholders at a purchase price of $1.00 per warrant (“Insider Warrants”). Ledecky purchased 2,500,000 of such warrants at such time for an aggregate purchase price of $2,500,000. Ledecky used his personal funds for such purchase.

On October 22, 2009, the Issuer consummated a business combination (the “Merger”) with Cullen Agricultural Technologies, Inc. (“Cullen Agritech”), as contemplated by the Agreement and Plan of Reorganization (the “Merger Agreement”), dated as of September 4, 2009, as amended, among Triplecrown, the Issuer, CAT Merger Sub, Inc. (“Merger Sub”), Cullen Agritech and Cullen Inc. Holdings Ltd. (“Cullen Holdings”). Prior to the Merger, the Issuer was a wholly owned subsidiary of Triplecrown, Merger Sub was a wholly owned subsidiary of the Issuer and Cullen Holdings was the sole stockholder of Cullen Agritech. Pursuant to the Merger, (i) Triplecrown merged with and into the Issuer with the Issuer surviving as the new publicly-traded corporation and (ii) Merger Sub merged with and into Cullen Agritech with Cullen Agritech surviving as a wholly owned subsidiary of the Issuer.

In addition, all of the outstanding securities of Triplecrown were automatically converted into like securities of the Issuer. Accordingly, in connection with the Merger:

Ledecky and Hat Tricks LLC were issued 6,630,000 shares of the Issuer’s Common Stock upon conversion of their Initial Shares (which shall hereinafter continue to be referred to as Initial Shares). However, pursuant to the terms of the Merger Agreement, Ledecky immediately surrendered 4,630,000 of his Initial Shares to the Issuer for no consideration and such shares were canceled.

Ledecky and Hat Tricks LLC were issued 6,630,000 warrants, each to purchase one share of the Issuer’s Common Stock, upon conversion of their Initial Warrants (which shall hereinafter continue to be referred to as Initial Warrants).

Ledecky was issued 2,500,000 warrants, each to purchase one share of the Issuer’s Common Stock, upon conversion of his Insider Warrants (which shall hereinafter continue to be referred to as Insider Warrants).

No funds were expended at such time to acquire the Initial Shares, Initial Warrants or Sponsors’ Warrants.

SCHEDULE 13D

Also in connection with the Merger, the warrant agreement governing the Triplecrown warrants, including the Initial Warrants and the Insider Warrants (all of which became Issuer warrants upon the completion of the Merger), was amended to (i) increase the exercise price of the warrants from $7.50 per share to $12.00 per share, (ii) extend the expiration date of the warrants from October 21, 2012 to October 21, 2013 and (iii) increase the price at which the stock must trade for the warrants to be called for redemption from $13.75 per share to $17.00 per share. The Insider Warrants became exercisable upon completion of the Merger. The Initial Warrants will not become exercisable until the last sales price of the Issuer’s Common Stock exceeds $13.75 per share for any 20 trading days within any 30-trading day period beginning January 20, 2010.

Item 4. Purpose of Transaction.

Ledecky acquired the shares of Common Stock described in this Schedule 13D for investment purposes.

Ledecky may from time to time acquire additional securities for investment purposes, or dispose of securities, in the open market or in private transactions. Ledecky beneficially holds Initial Warrants to purchase 6,630,000 shares of Common Stock, which are not currently exercisable and will not become exercisable within 60 days, and Insider Warrants to purchase 2,500,000 shares of Common Stock, which are currently exercisable.

At the date of this Schedule 13D, Ledecky, except as set forth in this Schedule 13D, has no plans or proposals which would result in:

(i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or

(j) Any action similar to any of those actions enumerated above.

Item 5. Interest in Securities of the Issuer.

Ledecky is the beneficial owner of 4,500,000 shares of the Issuer’s Common Stock, representing 600,000 shares of Common Stock held by Hat Tricks LLC, 1,400,000 shares of Common Stock held directly by Ledecky and 2,500,000 shares of Common Stock issuable upon exercise of the Insider Warrants held directly by Ledecky. Ledecky is the beneficial owner of 20.7% of the Issuer’s outstanding Common Stock. Ledecky has shared voting and dispositive power over the 600,000 shares of Common Stock held by Hat Tricks LLC and sole voting and dispositive power over the 1,400,000 shares held directly by him and the 2,500,000 shares of Common Stock issuable upon exercise of the Insider Warrants. The foregoing amounts do not include 6,630,000 shares of Common Stock issuable upon the exercise of Initial Warrants that are not currently exercisable and will not become exercisable within 60 days.

In the past 60 days, Ledecky effected the transactions described under Item 3 above and such transactions are incorporated by reference herein.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

All of the Initial Shares and Initial Warrants are held in escrow under an escrow agreement with Continental Stock Transfer & Trust Company, pursuant to which such securities will not be released from escrow until one year after the Merger (except (i) to an entity’s beneficiaries upon its liquidation, (ii) to relatives and trusts for estate planning purposes, (iii) by virtue of the laws of descent and distribution upon death or (iv) pursuant to a qualified domestic relations order).

The holders of the majority of the Initial Shares, Initial Warrants and the holders of the majority the Insider Warrants (or underlying shares) each will be entitled to make up to two demands that the Issuer register such shares or warrants (or underlying shares) pursuant to a registration rights agreement entered into with Triplecrown in connection with its initial public offering (which became an obligation of the Issuer as a consequence of the Merger). The holders of the majority of the Initial Shares and Initial Warrants can elect to exercise these registration rights at any time commencing nine months after the completion of the Merger. The holders of a majority of the Insider Warrants (or underlying shares) can elect to exercise these registration rights at any time. In addition, these holders have certain “piggy-back” registration rights on registration statements filed subsequent to such date. The Issuer will bear the expenses incurred in connection with the filing of any such registration statements.
