It is necessary to remember that “five do not mixâ€: 1. Farmyard manure such as human and animal excrement cannot be mixed with alkaline fertilizers such as grass ash, lime nitrogen, lime, calcium magnesium phosphate fertilizer. The main component of human and animal excrement is nitrogen, which is mixed with strong alkaline fertilizer and will neutralize failure.
2. Superphosphate can not be mixed with alkaline fertilizers such as grass ash, lime nitrogen and lime, which will reduce the effect of phosphate fertilizer. Phosphorus ore powder, bone powder and other insoluble phosphate fertilizers can not be mixed with alkaline fertilizers such as grass ash, lime nitrogen, lime, etc., mixed with organic acids in the soil, making phosphate fertilizer more difficult to dissolve, crops can not be absorbed.
3. Alkaline fertilizers such as calcium, magnesium and phosphate fertilizers cannot be mixed with ammonium nitrogen fertilizer. If the alkaline fertilizer is mixed with an ammonium nitrogen fertilizer such as ammonium hydrogencarbonate, ammonium sulfate, ammonium nitrate or ammonium chloride, the loss of ammonia volatilization and the fertilizer efficiency are reduced.
4. Unfertilized farmyard manure cannot be mixed with ammonium nitrate. If mixed with ammonium nitrate, the unfertilized farmyard manure will suffer losses in the process of decomposition and decay, reducing fertilizer efficiency.
5. Chemical fertilizers cannot be mixed with bacterial fertilizers. Chemical fertilizers have strong corrosiveness, volatility and water absorption. If mixed with bacterial fertilizers such as rhizobia, they will kill or inhibit live bacteria and invalidate bacterial fertilizers.
