Humic acid water-soluble fertilizer, officially named humic acid-containing water-soluble fertilizer, is a kind of water-soluble fertilizer containing humic acid. It is a liquid or solid water-soluble fertilizer made of humic acid suitable for plant growth as raw material, and adding a proper amount of major elements such as nitrogen, phosphorus and potassium or trace elements such as copper, iron, manganese, zinc, boron and molybdenum.
Humic acid may be unknown to many people. It is a natural macromolecular organic substance formed by microbial decomposition and transformation and geochemical process, and is mostly extracted from peat, lignite and weathered coal.
2. What are the functions of humic acid water-soluble fertilizer?
Humic acid water-soluble fertilizer contains humic acid. Compared with other water-soluble fertilizers, its function is different. General water-soluble fertilizers can only give crops a variety of essential nutrients. Humic acid water-soluble fertilizer can not only provide various necessary nutrients for crops, but also enhance nutrient efficiency, nourish roots, promote growth, regulate soil and raise ground temperature. Specifically, the functions of humic acid water-soluble fertilizer mainly include:
1, improving soil quality
(1) Improve soil physical properties: improve the formation of soil aggregate structure, improve soil fertility and water retention capacity, break soil hardening, improve drainage and ventilation, and raise ground temperature.
(2) Adjusting soil chemical properties: improving soil acid-base buffering capacity and adjusting acid-base; Chelate metal ions, reduce the concentration of heavy metal ions and reduce heavy metal poisoning.
(3) Improving soil microbial activity and soil microenvironment: providing carbon source for beneficial microorganisms, promoting their proliferation, increasing the number of beneficial microorganisms and inhibiting their growth and reproduction.
2. Fertilizer efficiency
Improve fertilizer efficiency and reduce fertilizer waste: chelate nutrient ions in soil solution, reduce nutrient loss and fixation, and improve adsorption utilization rate.
3. Improve crop yield and quality
(1) promotes the growth and development of roots and improves nutrient absorption.
(2) Improve crop disease resistance and promote crop growth and development.
(3) Improve the leaf membrane function and photosynthesis.
(4) Increase crop yield and improve the quality of agricultural products.
