    TERRA NITROGEN COMPANY, L.P. SUSPENDS PRODUCTION AT BLYTHEVILLE FACILITY

Sioux City, Iowa (June 26, 2003)-- Terra Nitrogen Company, L.P. (TNCLP) (NYSE
symbol: TNH) reported today that it will suspend ammonia and urea production at
its Blytheville, Ark., facility and lay off about 60 employees, or nearly 65
percent of its Blytheville workforce. The production suspension is due to
continued high natural gas prices and the seasonal decline in nitrogen
fertilizer demand and prices. The Blytheville facility, which represents 29 and
100 percent, respectively, of TNCLP's total ammonia and urea manufacturing
capacity, will resume production when ammonia and urea selling prices increase
and/or natural gas costs decrease to the point where the facility can operate
with positive cash flow.

Terra Nitrogen Company, L.P. is a leading manufacturer of nitrogen fertilizer
products.

Information contained in this release, other than historical information, may be

financial markets, general economic conditions within the agricultural industry,
competitive factors and price changes (principally nitrogen fertilizer selling
prices and natural gas costs), changes in product mix, changes in the
seasonality of demand patterns, changes in weather conditions, changes in
governmental regulations and other risks described in the "Factors That Affect
Operating Performance" section of TNCLP's current annual report.
