Terra Board of Directors Declares $7.50 per Share
Special Cash Dividend

SIOUX CITY, IOWA (October 29, 2009) — Terra Industries Inc. (NYSE: TRA) today announced that its Board of Directors has declared the previously announced special cash dividend of $7.50 per share. The record date and the payment date for the special cash dividend will be the same as those for Terra’s previously announced regular quarterly dividend, November 23, 2009 and December 11, 2009, respectively.

“Terra’s Board is committed to enhancing value for all shareholders and over the past three years 35% of Terra’s net income has been delivered to shareholders in the form of share repurchases and dividends,” said Terra President and CEO Michael Bennett. “Through the special cash dividend, Terra will return an aggregate of approximately $750 million to shareholders. In addition to this special cash dividend, we recently announced an agreement to purchase a 50% interest in Agrium Inc.’s Carseland, Alberta, Canada nitrogen production assets and certain U.S. assets. These actions are further examples of the Board’s commitment to providing shareholders with significant additional value for their investment in Terra.”

Terra’s common stock will begin trading without the special cash dividend and the regular dividend, on an ex-dividend basis, on December 14, 2009 (i.e., the first business day following the payment date). Shareholders of record on the record date who sell their shares on or before the payment date will lose their right to the special cash dividend and the regular dividend.

Based on its current estimates, the Company expects that approximately $1.00 to $1.50 of the special cash dividend will, for tax purposes, be classified as a return of capital. The tax character of the special cash dividend will be determined by the amount of earnings and profits for 2009, which will not be known until after the Company’s books are closed effective December 31, 2009.

Certain statements in this communication may constitute “forward-looking” statements within the

meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based upon assumptions as to future events that may not prove to be accurate. Actual outcomes and results may differ materially from what is expressed or forecasted in these forward-looking statements. As a result, these statements speak only as of the date they were made and Terra undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by law. Words such as “expects,” “intends,” “plans,” “projects,” “believes,” “estimates,” and similar expressions are used to identify these forward-looking statements. In particular, statements about Terra’s plans or intentions regarding the completion of the Carseland acquisition and the benefits to Terra from such acquisition are forward-looking statements and may not necessarily occur. Forward-looking statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. These risks, uncertainties and assumptions include, among others:

• the risk that the closing of the Carseland acquisition, which is conditioned on the completion of Agrium Inc.’s unsolicited bid for CF Industries Holdings, Inc., may not occur,

• risks related to potential acquisition transactions,

• changes in financial and capital markets,

• general economic conditions within the agricultural industry,

• competitive factors and price changes (principally, sales prices of nitrogen and methanol products and natural gas costs),
