Which fertilizers cannot be mixed in agricultural production?
Pure urea is a white crystalline solid, while the industrial product is small white or pale yellow granules, with a nitrogen content of 44-46%. It is only slightly hygroscopic, easily soluble in water, and is a neutral fertilizer; it has the highest nutrient content among solid nitrogen fertilizers. Because it is absorbed quickly through the leaves and has a high utilization rate, its yield-increasing effect is great, making it most suitable for foliar topdressing. The spraying concentration should be based on...
Rational application of fertilizers is key to agricultural production. In order to achieve rational fertilization and an effective match in the types and amounts of chemical and organic fertilizers, it is necessary to understand knowledge about fertilizer use. According to the acidity or alkalinity of their aqueous solutions, fertilizers can be divided into acidic fertilizers, alkaline fertilizers, and neutral fertilizers. In agricultural production, some fertilizers are acidic, such as superphosphate and potassium dihydrogen phosphate; some fertilizers are alkaline, such as plant ash and ammonium bicarbonate; while urea, potassium chloride, and others are neutral fertilizers. Acidic fertilizers and alkaline fertilizers cannot be mixed for use; once mixed, the fertilizer efficiency will be greatly reduced. So which fertilizers cannot be mixed for use in agricultural production?
Urea cannot be mixed with plant ash, fused calcium magnesium phosphate, or kiln ash potassium fertilizer. Ammonium bicarbonate cannot be mixed with plant ash, human excrement and urine, ammonium phosphate nitrate, ammonium phosphate, potassium chloride, phosphate rock powder, fused calcium magnesium phosphate, ammonium chloride, or urea. Superphosphate cannot be mixed with plant ash, magnesium phosphate fertilizer, or ash potassium fertilizer. Potassium dihydrogen phosphate cannot be mixed with plant ash, magnesium phosphate fertilizer, or ash potassium fertilizer. Ammonium sulfate cannot be mixed with ammonium bicarbonate, ammonia water, plant ash, or kiln ash potassium fertilizer. Ammonium chloride cannot be mixed with plant ash, fused calcium magnesium phosphate, or kiln ash potassium fertilizer. Ammonium nitrate cannot be mixed with plant ash, ammonia water, kiln ash potassium fertilizer, fresh barnyard manure, or compost. Ammonia water cannot be mixed with human excrement and urine, plant ash, potassium-nitrogen compound fertilizer, ammonium phosphate, potassium chloride, phosphate rock powder, fused calcium magnesium phosphate, ammonium chloride, urea, ammonium bicarbonate, or superphosphate. Ammonium phosphate nitrate cannot be mixed with compost, grass fertilizer, barnyard manure, or plant ash. Phosphate rock powder cannot be mixed with ammonium phosphate. Human and livestock excrement and urine cannot be mixed with plant ash or kiln ash potassium fertilizer.
