               TERRA INDUSTRIES INC. REPORTS THIRD QUARTER RESULTS

Sioux City, Iowa (Oct. 28, 2004)--Terra Industries Inc. (NYSE symbol: TRA)
announced net income of $6.5 million, or $.08 per share, on revenues of $377
million for the third quarter ended Sept. 30, 2004. This compares to the 2003
third quarter net loss of $4.5 million, or $.06 per share on revenues of $325
million.


For the first nine months of 2004 Terra posted net income of $42.5 million, or
$.55 per share, on revenues of $1.2 billion, compared to a net loss of $50.0
million, or $.66 per share, on revenues of $1.0 billion in the comparable 2003
period. The 2004 net income included $11.6 million of earnings attributable to
recovery of product claim costs (representing $17.9 million of operating income
less $6.3 million of related income taxes). The 2003 loss included a $27.0
million charge for "Impairment of long-lived assets" related to the Blytheville
production facility (representing a $53.1 million charge to operating income
less $9.9 million allocated to minority interest and a $16.2 million tax
benefit). Terra permanently closed the Blytheville facility on May 27, 2004.


Cash from operations before working capital changes was $40.8 million in the
2004 third quarter, compared to $21.0 million in the 2003 third quarter. Cash
flow from operations, which consists of "Net cash flows from operating
activities" less "Change in current assets and liabilities", is not a recognized
measure under GAAP, but might be considered a useful measure of cash flows
generated from operations that are available to repay debt and invest in the
business. At Sept. 30, 2004, Terra had cash and short-term investments totaling
$144.6 million.


The Nitrogen Products business segment recorded revenues of $326.0 million and
operating income of $25.2 million for the quarter, compared with revenues of
$277.3 million and operating income of $9.4 million for the 2003 third quarter.
For the 2004 first nine months, Nitrogen Products posted revenues of $1.0
billion and operating income, excluding the $17.9 million recovery of product
claim costs, of $98.7 million, compared with revenues of $0.8 billion and,
excluding the $53.1 million impairment charge, operating income of $1.3 million
in the 2003 first nine months.


The $15.8 million improvement in 2004 third quarter Nitrogen Products results
compared to those of the 2003 third quarter was due to higher product selling
prices, partially offset by higher natural gas costs. Ammonia, nitrogen
solutions, ammonium nitrate and urea selling prices for the 2004 third quarter
were 22, 31, 19 and 21 percent higher, respectively, than 2003 third quarter
prices. These higher prices reflect improved worldwide nitrogen product
supply/demand balances. Nitrogen Products natural gas unit costs for the
quarter, including approximately $4.2 million of cost increases due to forward
purchase contracts, were 21 percent higher than in the 2003 third quarter.





Excluding the 2004 recovery of product claim costs and 2003 impairment charges,
the improvement in 2004 year-to-date Nitrogen Products operating income as
compared to the same 2003 period was due to higher product selling prices
partially offset by higher natural gas costs. Ammonia, nitrogen solutions,
ammonium nitrate and urea selling prices were 17, 27, 30 and 12 percent higher,
respectively. Natural gas unit costs, net of about $8.4 million of cost
reductions realized from forward purchase contracts, increased 12 percent when
compared to the 2003 period.


The Methanol business segment reported 2004 third quarter revenues of $50
million and operating income of $0.6 million, compared with 2003 third quarter
revenues of $47 million and an operating loss of $1.1 million. The profit
increase was due to higher selling prices, partially offset by higher natural
gas costs.


The Methanol segment reported an operating loss for the 2004 first nine months
of $2.3 million, on revenues of $147 million. This compares to operating income
of $3.7 million on revenues of $161 million for the 2003 first nine months. The
decrease was caused by lower selling prices and sales volumes, and higher
natural gas costs.


Terra's forward purchase contracts at Sept. 30, 2004, fixed prices for
approximately 30 percent of its next 12 months' natural gas needs at about $25.6
million below the published forward market prices at the Sept. 30 date.


Said Michael L. Bennett, Terra's President and CEO, "Nitrogen markets remained
strong in the 2004 third quarter; our sales volumes were essentially limited by
our production volumes. The consensus nitrogen industry outlook is for continued
firm demand and favorable selling prices through at least the 2005 first half.
While these market conditions are encouraging, we continue to be concerned about
volatile natural gas markets as we enter the winter heating season.


"In August, Terra agreed to purchase Mississippi Chemical Corporation," Bennett
continued. "We're excited about the strategic opportunities Mississippi Chemical
can provide Terra both in the short- and long-term. We expect the transaction to
close as early as December 2004 and no later than the first quarter of 2005.


"We were also pleased to have completed this month Terra's private offering of
convertible preferred shares," Bennett concluded. "We expect the sale of these
shares to reduce our fixed cash requirements by more than $5 million per year."


Terra management will conduct a conference call to discuss these third quarter
results on Oct. 28, 2004 beginning at 3:00 p.m. (Eastern). A live webcast of the
conference call will be available from Terra's web site at
www.terraindustries.com, and will be archived for playback for three months.
