Diammonium phosphate is a completely water soluble crystalline product.
We produce the following types of Diammonium phosphate –
1. Diammonium phosphate is a mineral nitrogen-phosphorus fertilizer, completely soluble in water and intended for use in agriculture on all types of soils, especially effective on acidic soils. It contains nitrogen and phosphorus in a form easily absorbed by plants. The fertilizer is recommended for use in open and protected soil conditions (in greenhouses, hydroponics, sprinkling systems). It is used as the main and pre-sowing application, as well as top dressing at the beginning of the growing season, during the periods of budding and flowering, fruiting of various crops on various soils. Recommended for fertigation, root and foliar feeding of all plants. Diammonium phosphate can also be used as a component in the production of mixed mineral fertilizers, and is used as a raw material for the preparation of liquid complex fertilizers.
2. Diammonium phosphate Purified is used in various industries.
Diammonium phosphate is an ideal fire retardant. Thanks to its physical and chemical properties, it prevents fire and combustion. Due to the complete absence of insoluble impurities, complete dissolution of Diammonium phosphate is ensured and absorption into impregnated materials such as fabrics, plywood or wood is improved.
