Humic acid substances (activated lignite, weathered coal and biochemical humic acid substances) and chemical fertilizer components (nitrogen, phosphorus, potassium and medium and trace elements) are mixed in a certain proportion and made into granular fertilizer under specific temperature, pH, moisture and other conditions. We call it humic acid chelating fertilizer. After the chelating agent is applied to the soil, ammonia and mineral nutrients are released under the action of soil moisture and microorganisms (simple compounds or ions such as phosphorus, sulfur, potassium, calcium and magnesium) and organic complex nutrients. Due to the adsorption and complexation of humic acid and its stimulating effect on plant absorption, humic acid chelating agent has the characteristics of “controlling nitrogen, active phosphorus, stabilizing potassium and promoting micro”, so as to improve the utilization rate of fertilizer. Humic acid chelated fertilizer is made of 12 kinds of raw materials, including active organic matter and highly active humic acid, which are refined through multiple functions, with comprehensive nutrition and complete functions. One of the fertilizers contains nitrogen, phosphorus, potassium, and various medium and trace elements needed by crops that are lacking in the soil, directly supplying the growth and development of crops; the other is containing 15% organic matter equivalent to 3.5 tons of high-quality farm manure, improving soil and cultivating Fertility; the third is containing 10% humic acid to promote soil microbial activity, improve soil digestibility, increase soil nutrient supply, and break soil compaction; fourth, contain plant growth regulators, rooting powder, etc., to promote root development, strengthen roots, Wanggen, and coordinate the balanced supply of nutrients. The humic acid chelated fertilizer is a formula fertilization technology based on soil testing, that is, a formula determined according to the soil nutrient status, the law of crop fertilizer requirements and the comprehensive analysis of fertilization effects. The humic acid chelated fertilizer is refined by using polycyclic chelation technology through multiple actions. The release time and speed of nutrients are strictly controlled, consistent with the fertilizer requirement of crops, and the fertilizer validity period is extended to 100-110 days to ensure that the later period is not Defertilization, the utilization rate of chemical fertilizer reaches 50% to 60%, which is truly controllable and releaseable. Farmers call it a fertilizer with a switch. One is that the humic acid in the fertilizer, the ammonium ion in the nitrogen fertilizer, and the potassium ion in the potassium fertilizer are chelated to form ammonium humate and potassium humate, and the loss of nitrogen and potassium is relatively small. It not only prolongs the fertilizer effective period of nitrogen and potassium, but also reduces the volatilization and loss of nitrogen, and also reduces the loss of potassium. The second is that the chelating agent in fertilizer can chelate with metal ions, that is, it can clamp and clamp metal ions. Third, the colloid in humic acid can adsorb ammonium ions, potassium ions, nitrate ions, and phosphate ions in the soil, greatly improving fertilizer efficiency. Compared with ordinary slow and controlled release fertilizers, humic acid chelated fertilizers have multiple functions in slow and controlled release. Humic acid is a slow-release agent of nitrogen fertilizers, an activator of phosphate fertilizers, a protective agent of potash fertilizers, and a chelating agent of trace elements. The mixture has a slow release effect on nitrogen, phosphorus, potassium, and microelements, while ordinary slow-release fertilizers are only for nitrogen fertilizers and have no slow-release effect on other nutrients. This is the utilization rate of humic acid chelated fertilizers. The main reason for doubling.
Three effects of humic acid chelated fertilizer
Increase production and income, nourish land and fertilize fields:
The application of humic acid chelated fertilizer can firstly increase the soil aggregate structure, activate the soil, adjust the relationship between soil water, fertilizer, air and heat, increase soil organic matter content, and improve soil fertility; second, it can adjust soil pH, reduce soil salt damage, and relieve salt and alkali; Third, it can reduce soil toxic substances and heavy metal ions, without any negative effects in long-term use, and at the same time can increase the buffering capacity of the soil, and have a regulating effect on external acid and alkali.
Increased stress resistance: The stress resistance of things is mainly manifested in drought resistance, disease resistance, lodging resistance, and waterlogging resistance. The application of humic acid chelating fertilizer is mainly manifested in the developed root system, large root volume and long root system, especially the white roots of rice; the activity of beneficial microorganisms is vigorous and the growth of harmful bacteria is inhibited. Humic acid is both an activator of oxygen and a carrier of hydrogen. It can effectively stimulate the division of crop cells, making roots and buds grow vigorously, with more roots, long roots, early accumulation of dry matter, strong stalks, and resistance to stress Enhanced. The highly active organic matter, highly active humic acid, and high-tech companion in the fertilizer can effectively promote the activity and reproduction of microorganisms, enhance the rhizosphere microbial flora, and inhibit the activity of harmful flora, so it can reduce the occurrence of many soil-borne diseases.
