Mixed fertilizers have contraindications

When fertilizing in spring, fertilizing fertilizers with different nutrients can balance the soil and promote crop growth, but the following conditions cannot be mixed.
Alkaline fertilizers such as calcium magnesium phosphate can not be mixed with ammonium nitrogen fertilizer such as ammonium sulfate, ammonium hydrogencarbonate or ammonium chloride, otherwise it will increase the loss of nitrogen and reduce the fertilizer efficiency.
Farmyard manure such as human and animal excrement 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, it will neutralize failure when mixed with strong alkaline fertilizer.
Fertilizers cannot be mixed with biological fertilizers such as rhizobial fertilizers. Because chemical fertilizers have strong corrosiveness, volatility and water absorption, mixing with biological fertilizers will kill or inhibit the growth and development of microorganisms, and make the fertilizers ineffective.
Ammonia can not be mixed with manure, ash, ammonium phosphate, potassium chloride, urea, ammonium bicarbonate and other fertilizers. Ammonium bicarbonate cannot be mixed with plant ash, human excrement, potash and other nitrogen fertilizers. Ammonium sulfate cannot be mixed with plant ash or ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia water, and the like. The above-mentioned fertilizer mixture will cause acid-base neutralization reaction and reduce fertilizer efficiency.
Superphosphate cannot be mixed with alkaline substances such as plant ash, lime nitrogen, and lime. Because superphosphate contains free acid and is acidic, the above basic substance contains more calcium. When mixed, it will cause acid-base neutralization reaction, reduce fertilizer efficiency, and calcium will fix phosphorus.
