Generally speaking, chemical fertilizer refers to the fertilizer produced by chemical means in factories. Organic fertilizer is a kind of fertilizer that uses manure or dead branches and leaves in rural areas. It is also called farmyard manure. Both have their own advantages and disadvantages.
Fertilizer is an indispensable nutrient for our crops. Chemical fertilizers can supplement the nutrients needed for crops in time. Different fertilizers can play different roles on crops. Then, how to judge the lack of fertilizer in crops?
Chloride ions can reduce the starch and sugar content of vegetables, make the quality of vegetables worse, reduce the yield, and chloride ions remain in the soil, can lead to soil acidification, easy to cause soil decalcification.
Superphosphate contains a large amount of free acid, and continuous application of large amounts will cause soil acidification. Calcium magnesium phosphate fertilizer contains 25%-30% lime. A large amount of application will aggravate the soil alkalinity and deteriorate the physical and chemical properties.
Compound fertilizer has high nutrient content and few side components and good physical properties, which plays an important role in promoting high and stable yield of crops. The concentration difference is large, and attention should be paid to selecting the appropriate concentration to avoid direct contact with seeds and fertilizers.
