Exports of major nitrogen compounds surged upward in 1972, with a 31% increase
in the total amount of contained nitrogen exported and an $81 million increase
in value of the exports. Increased exports were due to the effects of devaluation
of the dollar, strong international demand and prices for nitrogenous fertilizers,
domestic price ceilings, and technical problems which delayed the startup
of new ammonia plants in several areas of the world. Exports are expected
to decline as

tassium nitrate which was imported from Israel. Bulk price was set at $87
per ton f.o.b. cars and trucks at warehouse. Prilled material was priced
at $91 per ton with a charge of $8.50 per ton extra for bagged material.
Hooker Chemical Corp. announced new prices for anhydrous ammonia of $67 per
ton f.o.b. its Tacoma, Wash., plant with freight allowed to destinations
in the States of Washington and Oregon and west 
of the Cascade Mountains. The prices were for agricultural and industrial
consumers (except for the paper and pulp industry) ,12 
Urea prices firmed during th~ year because of increased consumption and,
in part, because of the closures of a 250,000ton-per-year plant of E. I.
du Pont de Nemours & Co. and a 190,000-ton-per-year plant of Allied Chemical
Corp.'3

domestic demand moves into balance with domestic capacity. On a contained
nitrogen basis, total imports increased by only 4%. The most significant
changes in the import pattern were a 70% increase in urea imports and a 44%
drop in sodium nitrate imports.
