What are the advantages and disadvantages of chemically synthesized compound fertilizer? Compound fertilizer is a compound fertilizer produced by chemical (chemical) action or ammoniation granulation process, which is synthesized by obvious chemical reaction. The common types mainly include diammonium phosphate. Monoammonium phosphate, phosphorus nitrate fertilizer, potassium nitrate and potassium dihydrogen phosphate. This type of compound fertilizer contains elements required by two or more crops, has high nutrient content, can supply nutrients needed for crops in a balanced and long-term manner, and enhances the effect of fertilization and yield increase.
Secondly, such compound fertilizers are mostly granular, generally have low moisture absorption, no agglomeration, good physical properties, can improve the bad properties of some simple fertilizers, and are also convenient for storage, especially for mechanized fertilization. Finally, this type of fertilizer can be used as both a seed fertilizer and a base fertilizer and top dressing.
However, there are some disadvantages in the formation of compound fertilizer. For example, the ratio of nitrogen, phosphorus and potassium nutrients is relatively fixed and cannot be applied to the nutrient requirements of various soils and various crops. Therefore, in the process of compound fertilizer application, it is generally necessary to cooperate with the application of elemental fertilizers to meet the demand for nutrient types and quantities of various crops at different growth stages, and to achieve the balanced demand for high yield and nutrient.
In addition, chemical compound fertilizer is synthesized by chemical action of different elemental and compound fertilizers, so that it is difficult to meet the requirements of different nutrient fertilization techniques in the fertilizer application process, and the best application effect of various nutrients contained in the fertilizer cannot be obtained.
