Fertilizers can be classified into acidic fertilizers, alkaline fertilizers, and neutral fertilizers according to the acidity and alkalinity of their aqueous solutions. Some of the agricultural production of fertilizer is acidic, such as superphosphate, potassium dihydrogen phosphate and the like, there are basic fertilizer, such as ash, ammonium bicarbonate, and urea, potassium chloride, etc. are neutral fertilizer . Acidic fertilizers and alkaline fertilizers cannot be mixed. Once mixed, the fertilizer efficiency will be greatly reduced. Then the agricultural production which can not be mixed fertilizers it? Urea cannot be mixed with grass ash, calcium magnesium phosphate fertilizer and kiln ash potassium fertilizer. Ammonium not be mixed with ash, human waste, phosphate nitrate, ammonium phosphate, potassium chloride, phosphate rock, calcium and magnesium phosphate fertilizer, ammonium chloride and urea. Superphosphate cannot be mixed with grass ash, magnesium phosphate and ash potassium. Potassium dihydrogen phosphate cannot be mixed with plant ash, magnesium phosphate and ash potassium. Ammonium sulfate cannot be mixed with ammonium bicarbonate, ammonia water, grass ash and kiln ash potassium fertilizer. 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 water, kiln ash potassium fertilizer, fresh glutinous fertilizer and compost. Ammonia water can not be mixed with human excrement, plant ash, potassium and nitrogen mixed fertilizer, ammonium phosphate, potassium chloride, phosphate rock, calcium magnesium phosphate, ammonium chloride, urea, ammonium bicarbonate and superphosphate. Phosphate fertilizer cannot be mixed with compost, grass fertilizer, manure and grass ash. Rock phosphate and ammonium phosphate can not be mixed with. Human and animal waste can not be mixed with grass ash, kiln ash and potassium fertilizer.
