- The difference between chelated fertilizer and ordinary fertilizer
Chelated fertilizer refers to fertilizer that adds chelating agent to form chelate complex. Chelating agent is usually an organic matter with coordination effect, which can form stable chelate complex with cations in fertilizer (such as iron, zinc, calcium, etc.). In contrast, ordinary fertilizer simply provides the nutrients required by plants and cannot form stable complexes with soil.
- Mechanism of action of chelated fertilizer
Since chelated fertilizer can form stable complexes in soil, the nutrients it provides are not easily adsorbed and fixed by soil, thereby improving nutrient utilization. In addition, chelated fertilizer can also adjust soil pH, promote the reproduction of soil microorganisms, and further improve plant growth efficiency.
- Advantages and application scope of chelated fertilizers
Chelated fertilizers have the following advantages:
a. Improve nutrient utilization and reduce waste;
b. Enhance the ability of plants to absorb and utilize nutrients;
c. Regulate soil pH and improve soil quality;
d. Increase soil microbial activity and promote the health of soil ecosystems.
The application scope of chelated fertilizers includes various crops, fruit trees, vegetables, etc., especially for crops with short life cycles, high demand for trace elements, drought resistance and disease resistance.
- Disadvantages of ordinary fertilizers
Compared with chelated fertilizers, the main disadvantages of ordinary fertilizers are:
a. The nutrient effect is unstable and is easily adsorbed and lost by the soil;
b. Serious waste, a large amount of nutrients are wasted deep in the soil and cannot be absorbed and utilized by plants;
c. It is easy to cause soil acidification and have an adverse effect on the soil environment.
- Summary
Chelated fertilizers and ordinary fertilizers have significant differences in action mechanism and effect. Compared with ordinary fertilizers, chelated fertilizers can improve nutrient utilization and plant growth efficiency, and are a relatively excellent fertilizer variety. At the same time, when using chelated fertilizers, it is necessary to apply them reasonably according to the needs of specific crops to achieve better results.
