NPK 15:15:15 is a highly effective complex mineral fertilizer containing all the essential nutrients necessary for plant growth and development – nitrogen, phosphorus, potassium, sulfur and trace elements – boron, zinc, copper, manganese, iron, molybdenum.

This NPK is a complex mineral nitrogen-phosphorus-potassium fertilizer. It contains 15% N, 15% P2O5 and 15% K2O and produced in granules. NPK consists of ammonium nitrate, ammophos, diammophos, ammonium chloride, ammonium sulphate 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. Has good physical and mechanical properties, suitable for mechanized application to the soil.

NPK 15:15:15 can be used for the preparation of complex mineral fertilizers – fertilizer blends. Mineral fertilizer doesn’t contain nitrate nitrogen, nitrogen is in ammonium and amide form only.

The composition of this mineral fertilizer includes sulfur, which is necessary for plants. Sulfur is one of the basic elements of nutrition. It’s a part of proteins and amino acids, as well as in the composition of cystine and glutathin, which take an active part in the oxidation-reduction processes of the plant. In the presence of sulfur in fertilizer, plants are more resistant to drought, frost and soils salinization.

NPK 15:15:15 can be used for basic, pre-sowing application, as well as for feeding. It applies for all cultures. With basic fertilization on chernozem and heavy clay soils of the non-chernozem zone this fertilizer should be applied from autumn during plowing, and on light soils in spring. It’s used on all types of soils for basic and row application< and also for top dressing during the growing season for all crops.

The optimal ratio of nutrients makes it economically more profitable for the main application for cereals, technical, tilled, perennial grasses.
