Improvement of Soil Humus From biological organic fertilizer
2018-11-29
Organic compost fermentation process in bio-organic fertilizer production line converts organic raw materials into organic matter,stable humus and other nutrients. the Improvement of Soil Humus From biological organic fertilizer. And fulvic acid is the best and effective component in the humus. fulvic acid contains carboxyl group, phenolic hydroxyl group and other functional groups, has strong complexation, chelation and surface adsorption ability, can reduce the loss of ammonium nitrogen;Increase the movement distance of phosphorus in soil, inhibit the fixation of water-soluble phosphorus in soil, convert invalid phosphorus into effective phosphorus, and promote the absorption of phosphorus by root system;Fulvic acid can absorb and store potassium ions and improve the content of available potassium, especially the synergistic effect of potassium fertilizer.
The results showed that fulvic acid could increase utilization rate of nitrogen, phosphorus and potassium by more than 20%.
Humic acid, combined with pesticides, fungicides and herbicides, can enhance the efficacy and reduce toxicity.
1.Synergism on nitrogen fertilizer
The active groups of fulvic acid (including carboxyl group, hydroxyl group and some groups containing P, O, N and S) are generally electron donors, and it is easy to form coordination compounds with many electron acceptors (polyvalent metal ions, organic groups or ions), which are called complexes or chelates. For example, xanthic acid-urea, etc., is actually a complexation (chelation), which can make ammonium bicarbonate reduce the loss of ammonium nitrogen and improve the utilization rate of nitrogen fertilizer.Oxidative degradation of nitrofulvic acid can inhibit urinary enzyme activity and reduce urea volatilization.
The effect of fulvic acid and nitrogen on plant growth and development is obvious. When nitrogen and xanthofuric acid are sufficient, plants can synthesize more proteins and promote cell division and growth. Therefore, plant leaf area grows rapidly and more leaf area can be used for photosynthesis.It has obvious effect on promoting the growth and robustness of plants. After the application, the leaves quickly turn green, growth increased.
2.Synergism on phosphatic fertilizer
Degradation of nitrofulvic acid can increase the distance of phosphorus movement in soil, inhibit the fixation of water-soluble phosphorus in soil, convert invalid phosphorus into effective phosphorus, and promote the absorption of phosphorus by root system.Fulvic acid was used to protect water-soluble phosphate fertilizer or phosphor based compound fertilizer to reduce the fixation of phosphorus.Promote the absorption of phosphorus, improve the utilization rate of phosphorus fertilizer.The results showed that the addition of 10 ~ 20% fulvic acid in common calcium, heavy calcium or ammonium phosphate could increase the fertilizer efficiency by 10 ~ 20% and the phosphorus absorption by 28 ~ 39%.
Fulvic acid and phosphate fertilizer are involved in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement and other processes in plants.
3、Synergism on potash fertilizer
The combination of fulvic acid and potassium can promote photosynthesis, significantly improve the nitrogen absorption and utilization of plants, and quickly convert to protein, but also promote economic water use of plants.
The acid functional groups of fulvic acid can absorb and store potassium ions, and reduce the amount of potassium loss with water in sandy soil and leached soil. Fulvic acid can prevent the fixation of potassium in sticky soil and increase the amount of exchangeable potassium. Fulvic acid can dissolve potassium minerals, slowly increase the release of potassium and increase the content of available potassium in soil.Fulvic acid can also use its biological activity, stimulate and regulate the physiological metabolic process of crops, so as to increase potassium uptake by more than 30%.
4、Promote absorption of trace elements
In addition to NPK elements and other large amounts of elements, the growth and development of crops also need iron, boron, manganese, zinc, molybdenum, copper and other trace elements, which are the components of a variety of enzymes in crops, and have important effects on promoting the normal growth and development of crops, improving disease resistance, increasing yield and improving quality. Most of the trace elements in the soil are in an invalid state which is difficult for plants to absorb. Humic acid can chelate with iron, zinc and other trace elements to produce fulvic acid trace element chelates with good solubility and easy to be absorbed by plants, such as xanthic acid-zn, xanthic acid-mn, xanthic acid-fe, etc., which are conducive to root or leaf surface absorption and can promote the movement of trace elements from root to aboveground.
The experiment showed that the amount of ferric fulvic acid entering plants from roots, which increased the chlorophyll content by 15-45%, effectively solving the leaf yellowing caused by iron deficiency.
The application of soil humus in biological organic fertilizer and compound fertilizer can not only reduce crop burden, increase soil fertility and enrich soil bacterial matrix, but also improve crop yield and quality, so as to help enterprises to achieve long-term development goals of increasing yield, improving quality and maintaining land. So as to solve the problem of crop quality. We provide the details of how to start professional bio-organic fertilizer production line and 80,000 tons /year npk compound fertilizer production line.
