(1) Water-soluble phosphate fertilizer. Mainly through the general pass calcium phosphate, heavy superphosphate and ammonium phosphate (monoammonium phosphate, diammonium phosphate), suitable for all kinds of soil, all kinds of crops, but it is best used in neutral and calcareous soil. Ammonium phosphate is a compound nitrogen and phosphorus compound fertilizer, and its phosphorus content is high, which is 3 to 4 times that of nitrogen. When applied, except for leguminous crops, most crops must be directly applied with nitrogen fertilizer to adjust nitrogen and phosphorus ratios. Otherwise, it will cause waste or reduce production due to improper proportion of nitrogen and phosphorus.
(2) Miscible phosphate fertilizer. Phosphate nitrate fertilizer, which is also a binary compound fertilizer of nitrogen and phosphorus, is most suitable for application in dry land. It can easily cause denitrification loss in paddy fields and acidic soils.
(3) Soluble phosphate fertilizer. Including calcium magnesium phosphate fertilizer, calcium bicarbonate, precipitated phosphate fertilizer and steel slag phosphate fertilizer. This type of phosphate fertilizer is insoluble in water, but it is dissolved in the soil by weak acids and absorbed by crops. In calcareous alkaline soils, calcium is combined with soil and converted to insoluble phosphoric acid to reduce the effectiveness of phosphorus. Therefore, it is suitable for application in acidic soils.
(4) Insoluble phosphate fertilizer. Such as rock phosphate, bone meal and phosphorus sea bird fat, etc., only soluble in strong acid, insoluble in water. After being applied to the soil, it mainly depends on the acid in the soil to make it dissolve slowly and become a form that the crop can use. The fertilizer effect is very slow, but the aftereffect is long. It is suitable for use as a base fertilizer in acidic soils, and it can also be used in combination with organic fertilizer composting or chemical acidic and physiological acidic fertilizers. The effect is good.
