Ammonium nitrate

It is soluble highly efficient mineral ammonium nitrate, highly concentrated fertilizer. Contains 34.4% of nitrogen. Agriculture ammonium nitrate available in the form of granules of spherical shape. Among all the fertilizer it takes the first place for use in agriculture, which accounts for 55-60% fertilizer market. Has high hygroscopicity so as not dampen added additives absorbing moisture: ground limestone, chalk, phosphate fertilizer, phosphogypsum.
Applied to mineral nutrition of crops with the main, presowing making and feeding crops. The greatest efficiency is achieved by using of ammonium nitrate for early spring feeding winter wheat, winter oilseed rape and also for making a surface or locally to sowing or at sowing of spring crops, fertilizing the technical, vegetable and melon cultures. High effect obtained by co-depositing phosphorus and potassium. Forbidden ammonium nitrate to make a cucumber, zucchini, squash and pumpkin, so as contributes to the accumulation of nitrates.
This fertilizer is produced as follows: nitrogen is associated with hydrogen, in the result of that reaction produces ammonia; the ammonia subsequently oxidized to nitric acid, and when you combine ammonia with nitric acid, then will ammonium nitrate i.e. ammonium nitrate. Such agro-chemicals will be contain nitrogen in two forms, i.e. ammonium and nitrate (17% ammonium and 17% nitrate nitrogen, in the amount of 34% nitrogen).
The popularity of ammonium nitrate due to its versatility, as it fertilizer commonly used in agriculture for different crops and all types of soils.
This is an explosive, but its critical diameter (the smallest diameter the cylindrical explosive charge, which may propagation of detonation) so big (for raw unground nitrate of the order of several meters), and sensitivity to detonation of such minor, pure nitrate can be processed in the same way as inert salt.
The most widely in industry and mining used mixtures of ammonium nitrate with various types of hydrocarbon fuels other explosives, as well as a multicomponent mixture:
- compounds such as ammonium nitrate/diesel fuel (AST);
a liquid mixture of ammonium nitrate/hydrazine (astrolit);
- water-filled industrial explosives (aquanal, akvanit, etc.);
- mixtures with other explosives (Ammonite, demonic, etc.);
a mixture with aluminum powder (ammonal).
