- Differences between chelated fertilizer and compound fertilizer
a. Differences in nutrient activation
Chelated fertilizer is formed by combining nutrients together through chelation technology. It can activate phosphorus, potassium and trace elements fixed in the soil and convert these elements into components that are easily absorbed by crops. In contrast, although compound fertilizer contains a variety of nutrients, it may cause problems such as soil compaction, salinization and acidification after years of use.
b. Comparison of nutritional balance
Chelated fertilizer adds trace elements such as calcium, magnesium, boron, and zinc. These elements exist in a form that can be directly absorbed and utilized by crops, providing more balanced nutrition. The nutrients in compound fertilizer are relatively single and usually do not contain these trace elements.
c. Differences in crop absorption capacity and stress resistance
Chelated fertilizer can also improve the absorption capacity and stress resistance of crops for various nutrients, which means that even under adverse environmental conditions, crops can better absorb nutrients and resist diseases. Long-term use of compound fertilizers may cause soil problems and affect the healthy growth of crops.
d. Promoting effect on crop growth
The use of chelated fertilizer can promote the growth of crop roots, improve yield and quality, especially for fruit and vegetable crops, it can significantly improve their sugar content, coloring and fresh-keeping and storage. Although compound fertilizer can provide the basic nutrients required by crops, it is inferior in these aspects.
- The meaning and advantages of chelated compound fertilizer
Chelated compound fertilizer refers to a stable and efficient compound fertilizer that combines multiple nutrients with organic matter through chelation technology. It not only has all the advantages of chelated fertilizer, such as activating nutrients in the soil, providing balanced nutrition, enhancing crop absorption capacity and stress resistance, but also makes fertilization more convenient because of the combination of the characteristics of compound fertilizer.
In modern agricultural production, the application of chelated compound fertilizer is becoming more and more extensive. Its advantage is that it can provide comprehensive and balanced nutrition according to the needs of crops, improve the soil environment, promote the healthy growth of crops, and thus improve agricultural productivity. This fertilizer can not only meet the needs of field crops such as rice, wheat, corn, etc., but is also very suitable for fertilization of fruit trees, vegetables and flowers.
In summary, chelated fertilizer and compound fertilizer each have their own characteristics, while chelated compound fertilizer combines the advantages of both and has become an indispensable part of modern agricultural development. Through the scientific and rational use of this new type of fertilizer, we can effectively improve agricultural production efficiency, protect the environment and achieve sustainable development.
