Diammonium phosphate is a high-concentration, quick-acting fertilizer that can be applied to a variety of crops and soils.
Diammonium phosphate is a high-concentration, quick-acting fertilizer that can be applied to a variety of crops and soils.
It can be applied in autumn for tilling and in spring during sowing, as well as for pre-sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils.

1. Ammonium phosphate is a kind of water soluble quick acting compound fertilizer, in proportion to the content of AP²O5 and TN about 5.44:1, is one of the main varieties of high concentrations of phosphate and compound fertilizer. 2.Commonly used as additional fertilizer, is main raw material of compound fertilizer. 3. It is widely used in rice, wheat, corn, sorghum, cotton, fruits, vegetables and other all food crops and economic crops; Application to all kinds of soil, especially in drought little rain areas. 4 As a fertilizer, ammonium phosphate was the most suitable for crop growth. 5.In acidic soil than superphosphate, ammonium sulfate, in the alkaline soil than other fertilizer superiority.
Attentions:
1 Ammonium phosphate was acidic in the soil, and the seed was too close to the potential adverse effect. 2 Not with alkaline fertilizer mixed use, so as not to reduce fertilizer efficiency. For example the acid soil use lime in the South, using ammonium phosphate should be during few days after that.
