Early spring mixed fertilizer application six attention

1. Superphosphate cannot be mixed with alkaline fertilizers such as grass ash, lime nitrogen and lime. Because superphosphate contains free acid, it is acidic, and the above alkaline fertilizer contains more calcium. If the two are mixed, it will cause acid-base reaction, reduce fertilizer efficiency, and cause calcium to fix phosphorus, resulting in "two losses". .


2. Alkaline fertilizers such as calcium, magnesium and phosphate fertilizers cannot 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 cause and increase the volatilization loss of ammonia and reduce the fertilizer efficiency.


3. 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.


4. Fertilizers cannot be mixed with bacterial fertilizers such as rhizobium fertilizer. Because chemical fertilizers have strong corrosiveness, volatility and water absorption, if mixed with bacterial fertilizers, it will kill or inhibit the living cells and make the fertilizers ineffective.


5. Ammonia water 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 plant ash, human excrement, and potassium fertilizer. Ammonium sulfate cannot be mixed with grass ash or ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia water, etc. If the above-mentioned fertilizers are mixed and applied, it will cause acid-base neutralization reaction and reduce fertilizer efficiency.


6. Phosphorus ore powder, bone powder and other insoluble phosphate fertilizers 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.
