Humic acid is widely found in soil, lakes, rivers, and oceans. Peat, lignite, and weathered coal in nature contain a large amount of humic acid. It is an important factor affecting the ecological balance of the environment, and it is also a potential organic resource that can be vigorously developed and comprehensively utilized. Today, I will share the use and application of humic acid in the agricultural field.
Manufacturing humic acid fertilizers
Humic acid has the most research, development, and utilization in the agricultural field. Practice has proved that humic acid has a stimulating effect similar to hormones on the growth of crops such as cotton, tomatoes, and grapes. At present, humic acid has become the main component of foliar fertilizers, drought-resistant agents, regulators, and compound products used in agriculture.
Manufacturing humic acid liquid fertilizers
After humic acid is sprayed on the leaves, it can shrink the stomata on the leaves, reduce water transpiration, and enhance the drought resistance of crops. Humic acid has been mainly used as a plant regulator as a component of foliar fertilizers, and is gaining more and more widespread applications in agriculture.
Humic acid extracted from modified peat is dissolved in water and then added with macro and trace elements to make liquid fertilizer. When applied to vegetables, it can improve the quality of vegetables and increase the yield by about 20%. Humic acid plant nutrient solution made by compounding NPK macro elements and complex copper, iron, zinc, manganese and other trace elements in humic acid solution has the advantages of improving soil, enhancing the efficiency of nitrogen, phosphorus and potassium fertilizers, stimulating crop growth, increasing yield, and improving the quality of agricultural products.
