Exhibit 99.1

Terra Industries Inc. Reports Second Quarter Results,
Declares Dividend

SUMMARY $1.0 billion of cash and depositsQ2/09 vs. Q2/08: Gross margin 34.6%, relatively consistent. Ammonia, UAN and AN sales volumes decreased 30%, 26% and 10%. Ammonia, UAN and AN selling prices decreased 31%, 28% and 36%. Revenues reduced by $389.6 million, or 46%.Natural gas costs down 51%. OutlookStrong spring 2009 corn plantings indicate that nitrogen inventories likely drawn down, boding well for fall fill demand.Legislation taking effect in 2010 should stimulate TET environmental sales into mobile and stationary NOx abatement markets. Natural gas prices appear set to remain favorable.

SIOUX CITY, IOWA (July 23, 2009)—Terra Industries Inc. (NYSE: TRA) (“Terra”) announces income available to common stockholders for the 2009 second quarter of $80.5 million ($0.81 per diluted share), down from $202.2 million ($1.94 per diluted share) for the same period in 2008. For the 2009 first half, Terra’s income available to common stockholders was $110.4 million ($1.11 per diluted share), compared to $302.3 million ($2.91 per diluted share) for the 2008 first half.

Terra also declared a dividend of $0.10 per common share, payable Sept. 10, 2009, to holders of record as of Aug. 20, 2009.

Analysis of Second Quarter Results
Revenues for the 2009 second quarter totaled $453.5 million, compared to $843.1 million for the 2008 second quarter. This $389.6 million decrease in revenues from the 2008 to the 2009 second quarter was due to lower nitrogen products selling prices and sales volumes. These factors were caused by continued weakness in nitrogen markets due to the general economic slowdown, and customers’ reluctance to replenish inventories.

Lower natural gas costs due to reduced demand and ample supplies related to the overall sluggish economy helped to reduce production costs. Terra achieved a gross margin of 34.6 percent for the 2009 second quarter, compared to a gross margin of 35.1 percent for the 2008 period.

Second quarter cost of sales also reflects maintenance turnarounds at Terra’s Woodward ammonia and UAN plants. The cost of these activities was an estimated $4.9 million on a pretax basis ($3.3 million after tax), or $0.03 per diluted share.

Terra’s GrowHow UK joint venture continued to operate its Billingham and Ince locations at reduced rates for much of the second quarter. Sales volumes were down by approximately 36 percent in the 2009 second quarter versus the 2008 second quarter due to lower demand.

Other operating expenses included costs related to the CF Industries Holdings, Inc. unsolicited share exchange offer of approximately $12.6 million on a pretax basis ($8.5 million after tax), or $0.09 per diluted share.

Analysis of First Half Results
Revenues for the 2009 first half totaled $873.3 million, compared to $1,417.8 million for the 2008 first half. This $544.5 million decrease in revenues from the 2008 to the 2009 first half was due to lower nitrogen products selling prices and sales volumes, caused generally by the same factors as those affecting the 2009 second quarter.

Similar to the second quarter, lower first half natural gas costs due to reduced demand and ample supplies related to the economic slowdown helped to reduce production costs. Terra achieved a gross margin of 26.8 percent for the 2009 first half, compared to a gross margin of 32.7 percent for the 2008 period.

First half cost of sales also includes the curtailment of ammonia production at the Donaldsonville and Woodward plants for much of the first quarter, and maintenance turnarounds at the Yazoo City and Woodward facilities in the first and second quarters, respectively. The cost of these activities was an estimated $25.7 million on a pretax basis ($17.6 million after tax) or $0.18 per diluted share.

Other operating expenses for the 2009 first half included costs related to the CF Industries Holdings, Inc. unsolicited share exchange offer of approximately $14.3 million on a pretax basis ($9.8 million after tax), or $0.10 per diluted share.

Forward Natural Gas Position
Terra’s forward purchase contracts at June 30, 2009, fixed prices for about 15 percent of its next 12 months’ natural gas needs at about $4.6 million more than published prices for June 30, 2009 forward markets. These forward positions hedge production costs primarily associated with product that Terra has sold and plans to ship in the 2009 third and fourth quarters.

Cash Balances, Customer Prepayments and Share Buybacks
Cash balances totaled $1.0 billion and customer prepayments totaled $27.8 million at June 30, 2009. Terra expects to ship products under customer prepay agreements during the 2009 third and fourth quarters.

During the 2009 second quarter, Terra purchased no common shares under its share buyback program, which extends through June 30, 2010. Approximately 7.4 million shares remained available for repurchase under the program at June 30, 2009.

CEO’s Remarks
“Terra’s second quarter results reflect continued weakness in nitrogen products selling prices due to buyers’ hesitation to add to inventories,” said Terra President and CEO Michael Bennett.

“Industrial demand for ammonia remained relatively weak as the economy struggled to recover, and this led us to temporarily idle our Donaldsonville, Louisiana ammonia plant on July 1. It is likely we will restart the plant in August in light of improving Gulf ammonia prices and solid order activity.

“A positive outcome of the second quarter was that USDA reported higher-than-expected 2009 corn plantings, even as nitrogen imports were down sharply and domestic production rates were lower. This leads to the reasonable assumption that supply chain inventories were reduced significantly.

“Early third quarter activity indicates that nitrogen prices have reached a level that has clearly stimulated refill demand,” Bennett continued. “We are now taking orders for fall application, while adjusting the pace of off-season UAN fill sales to capture potential price improvements. We’re pleased to see returning demand for this fall and next spring’s crop.

“On the cost side, natural gas prices continue to be relatively low, helping to create moderate margins for our upgraded products, particularly UAN, ammonium nitrate and urea sales for NOx abatement.

“We are also gearing up for increased sales into diesel exhaust fluid markets in the 2009 second half as suppliers prepare to meet 2010 demand, which will be stimulated by new emission reduction requirements,” Bennett concluded. “Our recently announced relationships with Mack Trucks North America, Daimler and Volvo will provide our Terra Environmental Technologies group established additional channels through which to reach this growing market.”

Outlook
Terra continues to expect positive fundamentals for the 2009 second half:

	•		Healthy agricultural nitrogen demand—USDA’s recent planting report indicates U.S. growers planted an estimated 87 million acres of corn this spring, compared to its earlier estimate of 85 million acres. A portion of the nitrogen to fertilize this large crop appears to have come from inventory already in the supply chain. Terra expects an active fall fill season as customers seek to refill these depleted inventories.

	•		Strengthening nitrogen selling prices—Late in the second quarter, growers began to take delivery of product for sidedress and irrigation application, and dealers began to purchase UAN in preparation for their future needs. If the 2009/2010 fertilizer season progresses typically, Terra would expect to see nitrogen products selling prices gradually strengthen.

	•		Moderate natural gas costs—Most experts project that domestic natural gas prices will remain favorable through 2009 due to ample supplies and continued weak industrial demand. Terra’s third quarter results should also benefit from lower gas costs, as a substantial portion of derivative position values carried from the 2009 first quarter settled in the second quarter.

Factors that may temper the positive overall second half outlook are:

	•		Lower manufactured nitrogen volumes—Terra’s third quarter manufactured volumes should be slightly lower than those of last year’s third quarter, due to the idling of the Donaldsonville ammonia plant and market-related curtailments at other facilities.

	•		Unknown timing of industrial demand recovery—While Terra expects a recovery in industrial ammonia demand, it is difficult to predict when the rebound may occur since it will be tied to the improvement of the economy generally. For this reason, 2009 second half industrial ammonia sales volumes will likely lag behind last year’s levels.

Conference Call Details
Terra management will conduct a conference call to discuss these second quarter and first half results this afternoon at 3:00 ET. 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.
