humic acid

Humic acid is essential for improving fertilizer efficiency

The concept of humic acid is well thought out, especially in the context of ecology, safety and environmental protection. The concept of humic acid is based on the mineral-organic nutrition theory, with humic acid as a platform and a diversified structure to build a safe, healthy, economic and sustainable ecosystem.
Humic acid enhances plant fertilizer efficiency From soil fertilization to plant nutrition From soil fertilization based on nitrogen, phosphorus and potassium to minerals represented by humic acid – organic plant nutrition management is the inevitable result of scientific and technological progress. Since the establishment of the classic plant mineral nutrition theory for more than 100 years, chemical fertilizers have played an extremely important role in agricultural production, especially grain production. The contribution of chemical fertilizers to grain production has accounted for 50%. However, with the increase of chemical fertilizer application and long-term application, the decline of fertilizer efficiency, the decline of agricultural product quality, the reduction of crop resistance, the decline of soil organic matter, and the deterioration of soil environment have attracted more and more attention. This problem is particularly serious in China. We apply one-third of the world’s fertilizers, and produce only one-fifth of the world’s food. In order to solve this problem, we propose a series of solutions, including: soil testing and formula fertilization, slow release fertilizer release, water and fertilizer integration, etc., but only from the fertilizer product innovation and fertilization methods. The role of organic nutrition in plant nutrition has not yet received sufficient attention, especially the integrated application of mineral nutrition and organic nutrition. Studies have shown that plants can not only absorb elemental or ionic nutrients, but also absorb small molecules of organic matter, such as humic acid and amino acids. The biological effects of these small molecular organic actives on plant growth and development are also “equivalent and irreplaceable”. Organic nutrients are small molecular organisms that can be directly absorbed by plants, participate in plant metabolism, promote plant growth, and enhance plant resistance. Organic nutrients are not equivalent to biomass or organic fertilizers. After the biomass and organic fertilizer are applied to the soil, only the microbial degradation of the soil and the formation of small molecular active organic matter is the plant organic nutrition. The natural degradation of soil organic matter takes a long time. Cellulose can exist in the soil for 1500 years and lignin can reach 2500-3000 years. Therefore, the choice of activated mineral source humic acid or bio-humic acid using crop straw and kitchen waste is the “best choice” to supplement organic nutrition.
Humic acid is the intrinsic substance of the soil from the dispersing elements to the overall scheme. It is an inevitable link between soil, soil microorganisms, fertilizers and plants (crops).
