Early spring mixed fertilizer application seven attention

Recently, when I went to the countryside, I found that some farmers did not understand the performance of chemical fertilizers, blindly mixed fertilizers, and caused some winter vegetables to suffer from fat damage, causing unnecessary losses. Now introduce which fertilizers can not be mixed, so as to be used reasonably in production.

Superphosphate cannot be mixed with alkaline fertilizers such as ash, lime, 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". .

Alkaline fertilizers such as calcium magnesium phosphate can not be mixed with ammonium ammonia fertilizer. Because the alkaline fertilizer is mixed with ammonium nitrogen fertilizer such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, ammonium nitrate, etc., it will cause and increase the volatilization loss 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, lime nitrogen and lime. Because the main component of human and animal excrement is nitrogen, if mixed with strong alkaline fertilizer, it will neutralize and fail.

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.

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 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 reaction and reduce fertilizer efficiency.

Phosphorus ore powder, bone powder and other insoluble phosphate fertilizers cannot be mixed with alkaline fertilizers such as grass ash, lime ammonia, lime, etc., otherwise organic acids in the soil will be neutralized, making the insoluble phosphate fertilizer more difficult to dissolve, and vegetables cannot be absorbed and utilized.

Unfertilized farmyard manure cannot be mixed with ammonium nitrate, because the unfertilized farmyard manure can be absorbed and utilized by the decomposition and decay. If mixed with ammonium nitrate, the unfertilized farmyard manure will lose nitrogen during the decomposition process. Therefore, it is not possible to apply the same, otherwise the nitrogen of both will be damaged and the fertilizer effect will be reduced.
