Chelate fertilizer is a special fertilizer that combines nutrients with chelating agents (such as organic acids, amino acids, etc.) through special chelation technology. This combination can significantly improve the stability and utilization rate of nutrients in the soil, so that nutrients can be supplied to plants in a slower and more lasting way to meet the needs of long-term crop growth.
At the same time, chelate fertilizers also add a variety of trace elements such as calcium, magnesium, sulfur, iron, zinc, manganese, molybdenum, boron, and copper. These elements exist in a chelate form and are easier to be absorbed and utilized by plants.
The main difference between chelate fertilizer and compound fertilizer
a. Nutrient elements and utilization rate
Compound fertilizers mainly provide three macronutrients, nitrogen, phosphorus, and potassium, which are essential for crop growth. However, long-term use of compound fertilizers will cause nutrients to be fixed in the soil, reduce fertilizer efficiency, and may even cause problems such as soil compaction and salinization.
In contrast, chelate fertilizers have richer and more comprehensive nutrients, including not only macronutrients, but also a variety of trace elements. These elements form stable molecular clusters through chelation, which are not easy to degrade and lose in the soil, thus significantly improving the utilization rate of fertilizers. According to research, chelate fertilizers can increase crop absorption and utilization by more than 30% compared with traditional compound fertilizers.
b. Effects
The effects of compound fertilizers are mainly reflected in promoting crop growth and increasing yields, but due to their fast release rate, it is difficult to meet the continuous nutritional needs of crops. Chelate fertilizers can release nutrients according to the fertilizer requirements of crops to meet the needs of crops in different growth periods. It can not only activate phosphorus, potassium and other elements in the soil, but also improve the absorption capacity and stress resistance of crops to nutrients, promote the growth of crop roots, and thus improve the yield and quality of crops.
c. Impact on soil
Long-term use of compound fertilizers may have adverse effects on the soil, such as soil compaction, salinization and acidification. Chelate fertilizers have the effect of improving the soil environment. The added organic matter and amino acids help the reproduction of soil microorganisms and improve the air permeability, water retention and fertilizer retention of the soil. This is not only conducive to the growth of crops, but also enhances the sustainable utilization of the soil.
In general, compound fertilizers and chelate fertilizers have significant differences in nutrient elements and utilization rates, effects, and impacts on soil. In modern agricultural production, in order to meet the comprehensive nutritional needs of crops and achieve sustainable soil management, chelate fertilizers are gradually becoming a more efficient and environmentally friendly fertilizer choice.
