Terra to suspend ammonia production at Yazoo City facility

Sioux City, Iowa (December 27, 2005)—Terra Industries Inc. (NYSE symbol: TRA) announced today that effective Jan. 1, 2006, it will suspend ammonia production at its Yazoo City, Miss., facility due to high natural gas costs. Terra will begin in January the maintenance turnaround it had scheduled for February. The company expects to resume ammonia production at Yazoo City after the turnaround is complete and when natural gas costs decrease to a level that will allow the plant to operate with positive cash flow.

Terra plans to fulfill its Yazoo City sales commitments during the ammonia production suspension using imported ammonia to operate its upgrading plants.

Terra announced on Nov. 21 and Nov. 29, 2005, respectively, that it had suspended all production at its Woodward, Okla. facility and ammonia production at its Billingham, U.K. facility. Terra continues to produce ammonia at its other facilities in Courtright, Ont.; Port Neal, Iowa; Verdigris, Okla.; and Severnside, U.K. at reduced rates. Point Lisas Nitrogen Limited, the Trinidad ammonia manufacturing facility of which Terra owns 50%, continues to operate at full rates.

Terra Industries Inc., with pro forma 2004 revenues of $1.9 billion including the Mississippi Chemical acquisition, is a leading international producer of nitrogen products.
