Which fertilizers cannot be mixed? Remember these mixing taboos
Which fertilizers cannot be mixed? What are the reasons? We also ask knowledgeable readers to help explain. Because farmers do not understand the properties of chemical fertilizers and mix them carelessly, some crops wither, burn to death, and have reduced yields. Therefore, Zhongdi Web has compiled the reasons why fertilizers cannot be mixed, and they are listed in detail below for readers' reference....
Which fertilizers cannot be mixed? What are the reasons? We also ask knowledgeable readers to help explain.Because farmers do not understand the properties of chemical fertilizers and mix them carelessly, some crops wither, burn to death, and have reduced yields. Therefore, Zhongdi Web has compiled the reasons why fertilizers cannot be mixed, and they are listed in detail below for readers' reference.
1. Superphosphate cannot be mixed with alkaline fertilizers such as plant ash, lime nitrogen, and lime:
Because superphosphate contains free acid and reacts as an acid, while the above-mentioned alkaline fertilizers contain more calcium. If the two are mixed and applied, an acid-base reaction will occur, reducing fertilizer efficiency, and it will also cause calcium to fix phosphorus, leading to mutual harm.
Slightly soluble phosphate fertilizers such as phosphate rock powder and bone meal also cannot be mixed with alkaline fertilizers such as plant ash, lime nitrogen, and lime. Otherwise, they will neutralize the organic acid substances in the soil, making the slightly soluble phosphate fertilizer even harder to dissolve, and crops cannot absorb and utilize it.
2. Alkaline fertilizers such as calcium magnesium phosphate cannot be mixed with ammonium nitrogen fertilizers:
Because when alkaline fertilizers are mixed with ammonium nitrogen fertilizers such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, and ammonium nitrate, it will cause and increase ammonia volatilization loss and reduce fertilizer efficiency.
3. Farmyard manure such as human and livestock manure and urine cannot be mixed with alkaline fertilizers such as calcium magnesium phosphate, plant ash, lime nitrogen, and lime:
Because the main component of human and livestock manure and urine is nitrogen. If mixed with alkaline fertilizers, it will be neutralized and become ineffective.
Unrotted farmyard manure cannot be mixed with ammonium nitrate, because unrotted farmyard manure must undergo decomposition and rotting before it can be absorbed and utilized by crops. If mixed with ammonium nitrate, the nitrogen in the unrotted farmyard manure will be lost during decomposition, so they cannot be applied together. Otherwise, the nitrogen in both will be damaged, reducing fertilizer efficiency.
4. Chemical fertilizers cannot be mixed with bacterial fertilizers such as rhizobium fertilizer:
Because chemical fertilizers have relatively strong corrosiveness, volatility, and hygroscopicity. If mixed with bacterial fertilizers, they will kill or inhibit living bacteria and make the fertilizer ineffective.
