Although nitrites are the nitrogen compound chiefly used in meat curing, nitrates are used in certain specialty curing processes where a long release of nitrite from parent nitrate stores is needed. The use of nitrates in food preservation is controversial.
Ammonium nitrate-sulfate (30-0-0 + 6.5S) is a dry nitrogen fertilizer relatively new to the United States. It is manufactured by reacting anhydrous ammonia with a mixture of nitric acid and sulfuric acid. The nitrogen content of the product will vary depending on the proportion of nitric to sulfuric acid.he reacted material is concentrated, prilled and coated to prevent caking. In ammonium nitrate, one-half of the nitrogen is in the nitrate form, and the other half is in the ammonium form. Ammonium nitrate is the preferred form of nitrogen fertilizer when it is to be applied on the soil surface and not incorporated.
