According to Xu Minggang, a researcher at the Chinese Academy of Agricultural Sciences, a large number of statistics show that the contribution rate of chemical fertilizer production increase is 50%. In the 1970s, there was a lack of phosphorus in the soil, a shortage of potassium in the 1980s, and an accumulation of phosphate fertilizer in the 1990s. Today, the soil lacks organic matter, and organic fertilizer is added to increase crop yields. Stability is above 90%. In northern arid regions, 0.1% of organic matter is equivalent to 0.6 tons/ha of grain production capacity, while 0.1% of organic matter in southern rice area is equivalent to 0.8 tons/ha of grain production capacity. On average, soil organic matter is increased by 0.1%, and grain production capacity is improved. 10%-20%.
The soil organic matter is as important as it is explained above. Increasing soil organic matter increases the fertility of the soil. The more fertile the soil, the higher the food output of our farmers.
Summarized a few points here,
Effect of soil organic matter on soil fertility:
1) It is the main source of soil nutrients;
2) Promote soil structure formation and improve soil physical properties;
3) Improve soil fertility and buffering performance;
4) Humus has physiological activity and can promote crop growth and development;
5) Humus has a complexing effect that helps eliminate soil contamination
What is soil organic matter?
Refers to the life-derived material in the soil. Including soil microorganisms and soil animals and their secretions as well as soil in plant residues and plant secretions. In a broad sense, it includes all products that are extremely decomposed or synthesized by all organisms. In a narrow sense, the synthetic organic material, humus, is transformed by microorganisms. Sources of Organic Matter: The most important are the litters, stems, roots, flowers and fruits of higher plants. The type of organic matter, the broad organic matter includes two major categories: one is non-specific organic matter - biological remains and its decomposition of intermediate products; second is the special organic matter - humus. Chemical composition of non-specific organic matter
1, monosaccharides and organic acids; 2, polysaccharides: starch, hemicellulose, cellulose and so on. 3, protein; 4, lignin; 5, tannins, fats, waxes, resin 6, ash material - after the plant body after burning inorganic material, the main elements are Ca, Mg, K, Na, S, P, Fe, etc.
Soil organic matter is inextricably linked to soil fertility and food production. How do we know the organic matter content of this land before sowing? Therefore, there will be specialties for the detection of soil nutrient content, of course, including the detection of soil organic matter. The role of soil organic matter in post-fertilization can still be improved. But the premise is that we must know that the "disorder" can "prescribe the right medicine."
Here I introduce an instrument for detecting soil nutrients and organic matter produced by Zhejiang Top Instrument Co., Ltd.: Soil nutrient speed meter model: TPY-6 TPY-6A TPY-6PC has a remarkable result. If you have any questions, please call the 24-hour service hotline or login http://
