Chelate fertilizer is a fertilizer composed of some trace element compounds and organic substances, such as chelating agents such as EDTA, DTPA, PMIDA and basic fertilizer components such as nitrogen, phosphorus and potassium. This fertilizer is mainly used to supplement the lack of trace elements in the soil and improve the quality and yield of crops.
During the application process, chelate fertilizer will not interact with elements such as iron and manganese in the soil, and will not reduce the absorption efficiency of crops, thereby achieving the purpose of quickly and efficiently supplementing the missing elements.
Compound fertilizer is a mixed fertilizer composed of multiple basic nutrient elements (nitrogen, phosphorus, potassium). The components of organic fertilizer and trace element fertilizer can be adjusted to different degrees of adaptability according to the needs of crops.
The manufacture of compound fertilizer requires the use of chemical methods to organically combine multiple fertilizer components to achieve the purpose of reasonable fertilization and balanced nutrition. Compound fertilizer has the characteristics of stable and lasting fertilizer effect, and is suitable for large-scale, large-scale and high-yield crops.
Differences between chelate fertilizer and compound fertilizer
a. Different ingredients: Chelate fertilizer is mainly composed of trace element compounds and organic matter, while compound fertilizer is mainly composed of multiple basic nutrients.
b. Different functions: Chelate fertilizer is mainly used to supplement the lack of trace elements in the soil, while compound fertilizer is mainly used to provide the nutrients required by crops.
c. Different application methods: Chelate fertilizer is usually applied through liquid irrigation, while compound fertilizer can be applied in a variety of different ways (such as application on the surface of crops, direct spraying on leaves, etc.).
d. Different application amounts: Due to the differences in ingredients and functions, the application amounts of chelate fertilizer and compound fertilizer are also different. Generally speaking, the amount of chelate fertilizer is less than that of compound fertilizer.
In general, chelate fertilizer and compound fertilizer are fertilizers used for agricultural production. Each fertilizer has its own unique ingredients and functions, and its uses are different. In actual crop production, it is necessary to choose different types of fertilizers according to one’s actual situation and the needs of crops, so as to achieve better production benefits.
