Humic acid itself decide the importance in modern agriculture fertilzier
Fertilizer is the largest input of agricultural production. Which is related to the sustainable development of soil quality, agricultural farming, food security and ecological environment in China. Humic acid, as a “aggregate baby” of soil, is not only a good choice for improving fertilizer quality and increasing efficiency. But also greatly contributes to the sustainable development of environment-friendly agriculture in China.
In recent years, in the face of soil ecology, crop rhizosphere, plant leaf “trinity” plant three-dimensional and efficient fertilizer production system. Humic acid fertilizer “three innovative theories” came into being. That is, plant leaf environment control theory, crop rhizosphere environment control theory, soil ecological environment control theory.
The theory of leaf environmental control .
Plants emphasizes that leaves are the most important vegetative organs of plants except root. And it is a way for crops to obtain nutrients. If different forms and species of nutrients were sprayed on the leaves of crops, the effect of nutrient absorption and utilization on crops was the same as that of roots.
Plant leaves can not only absorb water. But also absorb other substances. Such as air, nutrients, pesticides etc. And it can quickly absorb nutrients into plants. On the other hand, because of the large area of leaves direct contact with air, sunlight and water vapor. The physiological activity is high and the nutrient absorption is faster than that of soil roots. Which can alleviate the symptoms of crop deficiency.
The theory of rhizosphere environmental regulation .
crops emphasizes that the rhizosphere environment is closely related to the root development of plants, and it is a complex and dynamic microecosystem formed in the process of plant growth, absorption and secretion. Which is different from soil in physical, chemical and biological properties. The so-called control refers to a certain amount of scope, specific to the product must be standardized control. Humic acid directly or indirectly regulates the soil microenvironment.
Soil ecological environment control theory
Making humic acid feed back soil is the core of soil ecological environment control theory. Humic acid is a kind of “aggregate treasure” for sustainable utilization of soil basic fertility. It is not only good with soil, but also good with fertilizer. It is the transportation “warehouse” of soil nutrients.
Disadvantage of taditional organic fertilizer
The traditional organic fertilizer contains more comprehensive and mild nutrients. Which is considered to be an excellent organic matter. However, with the fundamental change of agricultural production mode, such as human and animal manure, straw, animal and plant residues and other traditional organic matter has lost its natural nature. The production of traditional organic fertilizer has ceased. The wide use of feed additives containing high copper, high zinc and high arsenic. And coupled with the utilization rate of trace elements in livestock and poultry. The content of heavy metals in livestock and poultry feces exceed the standard. And the contents of some hormones, antibiotics, radioactive substances and other organic pollutants exceed the standard.
The deterioration of traditional organic fertilizer makes the synergistic effect of humic acid and chemical fertilizer more important. On one hand, humic acid improves the quality of chemical fertilizer by stabilizing, slow-release and controlling, prolonging fertilizer efficiency and improving fertilizer utilization rate. On the other hand, through the restriction of quantity, it can regulate and release the nutrient elements needed by plants. Promote the synthesis of effective substances. Balance all kinds of nutrients. And improve the quality of chemical fertilizer in shape.
Could humic acid replace chemical fertilizer?
Under the guidance of the “three innovative theories” , the best integration of humic acid with nitrogen, phosphorus and potassium can be realized. The utilization rate of the three fertilizers can be improved. The transformation and upgrading of chemical fertilizer industry can be added vitality. It should be emphasized that humic acid can be universal, but not omnipotent. Humic acid can not replace chemical fertilizer, can only be combined with chemical fertilizer, and achieve more.
Compared with the soil environment, no humic acid is impossible, no chemical fertilizer is ok. Compared with crop nutrient supply, without chemical fertilizer is not possible. Accompany with humic acid will be better. Compared with the nutritional supply of each growth period, organic matter is not equal to humic acid. Humic acid must be the best organic matter.
In the future, the “three innovation theories” of humic acid fertilizer will be used to guide the innovation of fertilizer industry. By constructing the three-dimensional and efficient fertilizer production system of plants. It is bound to promote the transformation and upgrading of chemical fertilizer industry in China and realize the sustainable development of environment-friendly agriculture in China.
