Is the effect of mixing superphosphate with farmyard manure good?
How is the effect of mixing superphosphate with farmyard manure? Please give an introduction. Superphosphate is a chemical phosphorus fertilizer commonly used in agriculture. Its main components are calcium carbonate and calcium dihydrogen phosphate. Calcium carbonate is difficult to dissolve in water and it is difficult for it to exert fertilizer efficiency. What can quickly exert fertilizer efficiency is the calcium dihydrogen phosphate, which is present in no large amount in superphosphate, but phosphate...
How is the effect of mixing superphosphate with farmyard manure? Please give an introductionSuperphosphate is a chemical phosphorus fertilizer commonly used in agriculture. Its main components are calcium carbonate and calcium dihydrogen phosphate. Calcium carbonate is difficult to dissolve in water and it is difficult for it to exert fertilizer efficiency. What can quickly exert fertilizer efficiency is the calcium dihydrogen phosphate, which is present in no large amount in superphosphate, but calcium dihydrogen phosphate easily combines with certain inorganic elements in the soil to form difficultly soluble substances and thus loses fertilizer efficiency. If superphosphate is crushed and mixed evenly with organic fertilizers such as chicken manure, pig manure, cow manure, barnyard manure, and miscellaneous soil manure, and then applied as a base fertilizer after being fully fermented, the fertilizer efficiency of superphosphate can be greatly improved. This application method has the following advantages:
It can reduce the contact between superphosphate and the soil, effectively avoiding soluble phosphorus from becoming difficultly soluble phosphorus and thus lowering fertilizer efficiency.
After superphosphate and organic fertilizer are mixed and applied into the soil, loose clumps are formed, water easily infiltrates and dissolves the soluble phosphorus, and the root acid secreted by plant root tips and the organic fertilizer act slowly on the difficultly soluble calcium carbonate at the same time, and can also gradually dissolve the calcium carbonate, thereby further increasing the utilization rate of phosphorus in superphosphate.
Mixing superphosphate with organic fertilizer and applying it can also change single fertilization into compound fertilization, increasing the types of elements applied to plants, and also promoting the plant's absorption and utilization of phosphorus, better meeting the nutritional needs of crops.
After superphosphate and organic fertilizer are mixed and applied into the soil, it can avoid affecting the normal life and activities of microorganisms in the soil due to the excessively high phosphorus concentration in the soil after conventional phosphorus application, thereby protecting soil activity.
