Chemical Synthesis Of Compound Fertilizers

Chemically synthesized compound fertilizer refers to the compound fertilizer that is made through chemical (chemical) action or ammoniation granulation process and is synthesized through obvious chemical reaction. Common types mainly include diammonium phosphate, monoammonium phosphate, nitrophosphate, Potassium nitrate and Monopotassium phosphate. This type of compound fertilizer contains elements required by two or more crops, with high nutrient content. It can provide the nutrients needed by crops in a balanced and long-term manner, improving the yield increase effect of fertilization.
Secondly, this type of compound fertilizer is mostly in the form of granules, generally with small moisture absorption, no agglomeration, and good physical properties. It can improve the adverse properties of certain elemental fertilizers and is also easy to store, especially beneficial for mechanized fertilization. Finally, this type of fertilizer can be used as both seed fertilizer, base fertilizer, and topdressing, with a wide range of applications.
But there are also some drawbacks to converting into compound fertilizers. For example, the proportion of nitrogen, phosphorus, and potassium nutrients is relatively fixed, which cannot be applied to the nutrient requirements of various soils and crops. Therefore, in the process of applying compound fertilizers, it is generally necessary to cooperate with the application of elemental fertilizers in order to meet the needs of various crops for nutrient types and quantities at different growth stages, and achieve the balance of nutrient requirements for high crop yield.
In addition, compound fertilizers are synthesized through chemical reactions of different elemental and compound fertilizers, which makes it difficult to meet the requirements of crops for different nutrient fertilization techniques during the fertilizer application process and cannot achieve the optimal application effect of various nutrients contained in the fertilizer itself.
