Fertilizers | NPK (N:P:K = 16:16:16)


GOST/TC TC 113-03-466-91 w/am. 1,2,3,4,5
APPEARANCE AND PROPERTIES

NPK is a compound fertilizer each granule of which consists of Potassium, Phosphorus, Nitrogen and small amounts of Sulphur. Due to this fact and that NPK is produced in granules an even distribution of nutrients in the soil is achieved. Sulphur and Nitrogen as part of this mineral fertilizer are involved in the synthesis of protein by the plants that results in increasing nutritional value of grain and bean cultures. Besides the sulphur facilitates the increasing of content of oil in plant seeds and enhances resistance of plants to drought, disease and low temperature impacts.
NPK facilitates not only the increase of nutritional value and crop yields but as well provides the greater strength of stem, prevents the lodging of the plants under the weather conditions. NPK is non-hygroscopic granules which do not cake. The fertilizer is highly concentrated; the nutrient content is not less than 40%, which ensures the small consumption of the fertilizer

USAGE

N PK (N:P:K = 16:16:16) — is a highly effective complex mineral fertilizer, which contains in assimilable form main nutrient elements necessary for plants growth and development - Potassium, Phosphorus, Nitrogen. Especially effective on clay, sand and bog peat soils. The fertilizer is suitable for mechanized application to the soil. Used for the main and local application in rows at seeding, and for plant nutrition.

STORAGE NPK — is a granulated product which does not cake during long-term storage due to the processing of condensing supplements.
NOTE NPK is hardly combustible product; dust is explosive. At the temperature more than 200 oС decomposes with the toxic gases excretion.
