1. Farmyard manure can not be mixed with alkaline fertilizers such as plant ash, lime nitrogen, lime, calcium magnesium phosphate fertilizer.
Because farmyard manure is mainly human and animal manure, the main component of which is nitrogen, if it is mixed with strong alkaline fertilizers such as plant ash, acid-base neutralization will occur and the fertilizer will become ineffective.
2. Superphosphate can not be mixed with alkaline fertilizers such as plant ash and lime nitrogen.
The mixing of superphosphate with alkaline fertilizers such as plant ash and lime nitrogen will reduce the effectiveness of phosphorus. Insoluble phosphate fertilizers such as phosphate rock powder and bone meal should not be mixed with alkaline fertilizers such as plant ash and lime nitrogen. Otherwise, the insoluble phosphate fertilizers will be more difficult to dissolve and the crops cannot be absorbed and utilized.
3. Alkaline fertilizers such as calcium magnesium phosphate fertilizers cannot be mixed with ammonium nitrogen fertilizers.
If alkaline fertilizers are mixed with ammonium nitrogen fertilizers such as ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride, etc., it will increase the volatility of ammonia and reduce fertilizer efficiency.
4. Immature farmyard manure cannot be mixed with ammonium nitrate.
Immature farmyard manure must be decomposed and decomposed before it can be absorbed and utilized by crops. If the unripe farmyard manure is mixed with ammonium nitrate, the farmyard manure will decompose the nitrogen in the ammonium nitrate produced during the decay process, thereby reducing fertilizer efficiency.
5. Chemical fertilizers cannot be mixed with bacterial fertilizers.
Chemical fertilizer has strong corrosiveness, volatility and water absorption. If it is mixed with bacterial fertilizers such as rhizobia, it will kill or inhibit live bacteria and make the bacterial fertilizer ineffective.
6. Urea cannot be mixed with plant ash, calcium magnesium phosphate fertilizer and kiln ash potash fertilizer.
7. Ammonium bicarbonate cannot be mixed with plant ash, human feces and urine, nitrophosphate, ammonium phosphate, potassium chloride, scale mineral powder, calcium magnesium phosphate fertilizer, ammonium chloride and urea.
8. Potassium dihydrogen phosphate can not be mixed with plant ash, calcium magnesium phosphate fertilizer and kiln ash potash fertilizer.
9. Ammonium sulfate cannot be mixed with ammonium bicarbonate, ammonia water, plant ash and potash fertilizer of kiln dust.
10. Ammonium chloride cannot be mixed with plant ash, calcium magnesium phosphate fertilizer and kiln ash potash fertilizer.
11. Ammonium nitrate cannot be mixed with plant ash, ammonia water, kiln dust, potash fertilizer, fresh manure and compost.
12. Ammonia water cannot be mixed with human feces, plant ash, potassium-nitrogen fertilizer, ammonium phosphate, potassium chloride, phosphate rock powder, calcium magnesium phosphate fertilizer, ammonium chloride, urea, ammonium bicarbonate and superphosphate.
13. Nitrophosphate cannot be mixed with compost, grass manure, barn manure, and plant ash.
14. Phosphate rock powder cannot be mixed with ammonium phosphate.
15. Human and livestock manure and urine cannot be mixed with plant ash, kiln ash and potash fertilizer.
