Compound Fertilizer
NPK Compound/Complex Fertilizer
NPK Compound/Complex Fertilizers which contain Nitrogen(N), Phosphate(P2O5) and Potassium(K2O) usually are produced by mixing straight fertilizers. In some cases, chemical reactions occur between the two or more components. In order to extend the fertilizer efficiency period and easy for application , transportation & storage, compound fertilizers which contain insoluble matters are generally made into granular by granulation process.
Granular
Compound Fertilizer is normally applied into the soil directly. Nutrients
dissolved in the soil can be absorbed by crops roots. Most granular fertilizers
are quick-released and fast-acting.
Formulation
can be adjusted according to natural condition of local soil, variety of the
crops, different growing periods and application methods. Chlorine-based,
sulphur-based, urea-based, and nitrate-based formulations are available.
Medium
Element (Ca, Mg, S) and Trace Element (Fe, Zn, Cu, Mn, B, Mo) or (EDTA-Fe,
EDTA-Zn, EDTA-Cu, EDTA-Mn) can be added as special using fertilizers.
