Appropriate application of fertilizers is the key to agricultural production. In order to achieve reasonable fertilization and achieve effective collocation of fertilizers and organic fertilizers, the knowledge of fertilizer use must be understood.
Fertilizer according to the acidity of its aqueous solution can be divided into acidic fertilizers, alkaline fertilizers, neutral fertilizers. Some agricultural fertilizers are acidic, such as superphosphate and potassium dihydrogen phosphate. Some fertilizers are alkaline, such as grass ash and ammonium bicarbonate, while urea and potassium chloride are neutral fertilizers. Acidic fertilizers and alkaline fertilizers cannot be used together. Once they are mixed, the fertilizer efficiency will be greatly reduced. What fertilizers cannot be used in agricultural production?
Urea can not be mixed with grass ash, calcium magnesium phosphate fertilizer and kiln ash potassium fertilizer. Ammonium bicarbonate cannot be mixed with grass ash, human waste, nitrophosphate, ammonium phosphate, potassium chloride, phosphate rock, calcium magnesium phosphate, ammonium chloride, and urea. Superphosphate can not be mixed with grass ash, magnesium phosphate fertilizer and ash potassium fertilizer. Potassium dihydrogen phosphate cannot be mixed with grass ash, magnesium phosphate fertilizer and ash potassium fertilizer. Ammonium sulfate cannot be mixed with ammonium bicarbonate, ammonia, grass ash, and kiln ash. Ammonium chloride cannot be mixed with grass ash, calcium magnesium phosphate fertilizer and kiln ash potassium fertilizer. Ammonium nitrate cannot be mixed with grass ash, ammonia, kiln ash, fresh manure and compost. Ammonia cannot be mixed with human waste, grass ash, potassium-nitrogen compost, ammonium phosphate, potassium chloride, phosphate rock, calcium magnesium phosphate, ammonium chloride urea, ammonium bicarbonate, and superphosphate. Nitrophosphate fertilizer cannot be mixed with compost, grass fertilizer, manure, and plant ash. Phosphorite powder cannot be mixed with ammonium phosphate. Human and animal waste cannot be mixed with grass ash and kiln ash potash.
