Which fertilizers cannot be mixed

Insoluble phosphate fertilizers such as phosphate rock powder and bone powder cannot be mixed with alkaline fertilizers such as grass ash, lime ammonia and lime. Otherwise, the organic acids in the soil will be neutralized, making the poorly soluble phosphate fertilizer more difficult to dissolve, and the crops cannot be absorbed and utilized.
Alkaline fertilizers such as calcium magnesium phosphate can not be mixed with ammonium ammonia fertilizer. Because the alkaline fertilizer is mixed with ammonium ammonia fertilizer such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, etc., it will accelerate the evaporation of ammonia and reduce the fertilizer efficiency.
Farmyard manure and other farmyard manure cannot be mixed with alkaline fertilizers such as calcium magnesium phosphate, grass ash and lime. Because the main component of human and animal excrement is nitrogen, if mixed with strong alkaline fertilizer, it will neutralize and fail.
Ammonia can not be mixed with human excrement, plant ash, potassium fertilizer, ammonium phosphate, potassium chloride, urea, ammonium bicarbonate, etc. Ammonium bicarbonate cannot be mixed with grass ash, human excrement, potassium fertilizer or nitrogen fertilizer. Ammonium nitrate cannot be mixed with grass ash, ammonia water, etc.
