1, superphosphate and organic fertilizers. Superphosphate and organic fertilizers can increase the effect of phosphate fertilizer. Because the organic fertilizer surrounds the outside of the superphosphate, it reduces the contact with the soil and prevents the fixation of phosphorus. At the same time, the organic acids produced by the decomposition of organic fertilizers can also dissolve insoluble phosphorus, which will help the crops absorb and use. The mixture of the two can also reduce the loss of nitrogen in organic fertilizers and play a role in the nitrogen retention by phosphorus.

2. Add superphosphate to human waste. The addition of 5%-10% of superphosphate to human excreta will not only reduce ammonia volatilization in human excreta, but also supplement phosphorus nutrition. Both complement each other.
3, superphosphate and ammonium sulfate. When superphosphate is mixed with ammonium sulfate, part of monoammonium phosphate and calcium sulfate will form, which can both supply crop nitrogen and phosphorus, and can also partly improve the physical and chemical properties of these two kinds of fertilizers.
4, superphosphate and phosphate rock powder. When superphosphate and phosphate rock are mixed and applied, the former can ensure the phosphorus requirement of the seedling stage of the crop, and the latter can be used for the vigorous growth period of the crop, so that the whole growth period of the crop will not be deficient in phosphorus.
5, organic fertilizer and ammonia. Per hundred kilograms of organic fertilizer plus 3-4 kilograms of mixed ammonia water, can reduce the volatilization of ammonia, but also can adjust the carbon and nitrogen ratio of organic fertilizers, but also accelerate the maturity of compost.
6. Phosphorite powder and ammonium sulfate. The combination of phosphate rock and ammonium sulfate can not only eliminate the physiological acidity of ammonium sulfate, but also enhance the fertilizer efficiency of phosphate rock, which is beneficial to the growth and development of crops.
7, ammonium bicarbonate and urea can not be mixed. The amide nitrogen in urea can not be absorbed by crops. Only by the action of urease in soil, it can be used by crops after it is transformed into ammonium nitrogen. When ammonium bicarbonate is applied to the soil, the soil solution causes an acidic reaction in the short term, which accelerates the volatilization of nitrogen in urea, so it cannot be mixed and applied.
8, ammonium bicarbonate can not be mixed with bacterial fertilizer. Ammonium bicarbonate and bacterial fertilizer are foes, because ammonium bicarbonate emits a certain concentration of ammonia, which is poisonous to the active bacteria of the bacterial fertilizer. If used in combination, the fertilizer will lose its fertilizer efficiency.
