In winter, the temperature is low, the microbial activity is weakened, and the fertilizers that need to be converted are slow. In winter, vegetable growth requires adequate fertilizer. The solution to this contradiction is to pursue quick-acting fertilizers.
Nitrogen fertilizer can use ammonium bicarbonate, phosphate fertilizer should use superphosphate as much as possible, potassium fertilizer can choose potassium chloride, compound fertilizer can use 45% ternary compound fertilizer, and farmyard manure can use decomposed human excrement.
Calcium superphosphate contains 14-20% of effective phosphorus pentoxide, which is a water-soluble quick-acting phosphate fertilizer, and its fertilizer efficiency is faster than that of calcium magnesium phosphate.
