Based on the above points, ammoniated compound fertilizer has the characteristics of uniform granulation, bright color, stable quality, sufficient nutrients, easy to dissolve and be absorbed by crops, etc., especially as seed fertilizer is relatively safe for seeds.
The types of fertilizers can be divided into two types: inorganic fertilizer and organic fertilizer.

Inorganic fertilizer is chemical fertilizer, such as various nitrogen, phosphorus, potassium fertilizer or compound fertilizer. Chemical fertilizers are commonly used in the planting industry: diammonium phosphate, urea, potassium sulfate, potassium chloride, various compound fertilizers, and long-acting fertilizers such as stone, also called superphosphate, can be used on fruit trees.
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.
