Today, as we continue to explore the path of sustainable agricultural development, more and more agricultural practitioners have begun to pay attention to environmental protection and soil improvement, and are looking for fertilizers that can coexist harmoniously with nature. As a widely recognized green agricultural product, humic acid fertilizer has a reputation as “black gold” in the agricultural industry due to its significant effects and functions. The following will fully interpret the magical effects and applications of humic acid fertilizers.
Humic acid can be divided into humic acid powder, humic acid granules and flake humic acid according to its appearance.
The benefits of humic acid in agriculture are mainly reflected in the following aspects:
1. Improve soil structure: Humic acid can promote the formation of soil aggregate structure, enhance the soil’s ability to retain water and fertilizer, reduce the loss of effective nutrients, and provide fertilizer for a long time. It can also adjust soil pH, increase soil buffering capacity, and improve acidic soil and saline-alkali land.
2. Improve the utilization rate of chemical fertilizers: When humic acid is combined with nutrients such as nitrogen, phosphorus, and potassium, it can increase the yield rate of nitrogen fertilizers, more than double the utilization rate of phosphorus fertilizers, and promote the dissolution of other insoluble nutrients, improve the utilization rate of various nutrients, and reduce fertilizer loss.
3. Stimulate crop growth: Humic acid can enhance the activity of various enzymes in crops, improve the ability of crops to absorb water and nutrients, accelerate growth and development, mature early, and promote root development.
4. Enhance crop resistance: After being applied to the soil, humic acid can darken the soil color, which is conducive to increasing ground temperature and enhancing the ability of crops to resist cold and frost. In addition, it can also improve the ability of crops to resist drought, disease, and salinity.
5. Improve the quality of agricultural products: Humic acid helps to improve the taste, color and other quality indicators of agricultural products and produce better quality agricultural products.
6. Environmentally friendly: Humic acid uses less and has a high utilization rate, which meets the requirements of food production safety and low-carbon agriculture. It can reduce the use of chemical fertilizers and reduce the negative impact of agriculture on the environment.
