Nitroammophos 16:16:16 (NH4H2PO4 + NH4NO3 + KCL) is a complex universal mineral nitrogen-phosphorus-potassium fertilizer with a high and different ratio of nutrients. It’s a granule of light pink color. It doesn’t cake, has 100% friability and not hygroscopic. All salts, which are part of nitroammophos, are soluble in water. A high concentration of nutrients, which is at least 40% (in total nitrogen, phosphorus, potassium) allows to significantly reduce (in comparison with simple fertilizers) the costs of transportation, storage and applying into the soil.

Nitroammophos consists of ammonium nitrate, ammophos, diammophos, ammonium chloride, ammonium sulfate and potassium nitrate obtained in a single process with the interaction of ammonia, nitric and phosphoric acids with the addition of potassium chloride and potassium sulfate.

This fertilizer is produced only in granular form and has good physical and mechanical properties, it’s suitable for mechanized application into the soil.

Nitroammophos NPK 16:16:16 is applied as the main and pre-sowing fertilizer on all types of soils under all agricultural crops. This NPK is most effective on chernozems and gray soils with irrigation. During main application at chernozems and soils with heavy granulometric composition in the non-chernozem zone it’s advisable to apply nitroammophos at autumn plowing, and also in the spring on soils with light granulometric composition.
