The concept of humic acid fertilizer is getting more and more. Especially in the background of ecology, safety and environmental protection.The concept of humic acid is based on the theory of mineral-organic nutrition. Taking humic acid as a platform and integrating multiple elements to build a safe, healthy, economic and sustainable ecological system.
1. From soil fertilization to plant nutrition, from nitrogen, phosphorus, potassium based soil fertilization to humic acid represented by the mineral-organic plant nutrition management is the inevitable progress of science and technology.
Over the past 100 years since the establishment of the classic plant and mineral nutrition theory. Chemical fertilizers have played an extremely important role in agricultural production, especially in grain yield increase. Chemical fertilizers have contributed 50% to grain yield increase. But with the increase of applying fertilizer content and long-term fertilization, fertilizer efficiency decline, the agricultural product quality decline, and resistance of crops reduce, soil organic matter decline, soil environmental degradation problems and so on. Which more and more aroused people’s concern. The problem is particularly serious in China. We use a third in the world of chemical fertilizer, and the production of food is only about 1/5 of the world.
To solve this problem, we put forward a series of solutions. Including: soil testing formula fertilization, slow and controlled release fertilizer promotion, water and fertilizer integration, etc., but only efforts from the fertilizer product innovation and fertilization method.The role of organic nutrition in plant nutrition has not been paid enough attention especially the integrated application of mineral nutrition and organic nutrition.
2. Humic acid efficiency as organic fertilizer.
Studies have shown that plants can absorb not only elemental or ionic nutrients, but also small molecules of organic compounds. Such as humic acid fertilizer and amino acid etc. The biological effects of these small molecules on plant growth and development are “equally important and irreplaceable”. Organic nutrients refer to small molecular organics that can be directly absorbed by plants. Participate in plant metabolism. Promote plant growth and enhance plant resistance. Organic nutrients are not the same as biomass and organic fertilizer. When biomass and organic fertilizer are applied into the soil. It is only when they are degraded by soil microorganisms to form small molecular active organic compounds that plant organic nutrition takes place.
Humic acid is the source material of soil
Natural degradation of soil organic matter takes a long time. Cellulose can exist in soil for 1500 years and lignin for 2500-3000 years. Therefore, the selection of activated humic acid from mineral sources or biological humic acid from crop straw and kitchen waste is the “best choice” to supplement organic nutrition. Humic acid is the source material of soil ,and an inevitable link among soil, soil microorganisms, fertilizers and crops.
