Without it in the soil, no matter how much fertilizer is applied, the effect will not be good!

    The soil in the soil is more important than the nitrogen, phosphorus and potassium, that is the soil "organic matter", as everyone may know, our country has vigorously promoted the use of organic fertilizers in recent years, and the biggest advantage of organic fertilizers is the rich organic matter content! my country's commercial organic fertilizer standard stipulates that the organic content of organic fertilizer must be ≥45%. Therefore, increasing the application of organic fertilizer can supplement the soil organic matter!

    What are the effects of soil organic matter?

    1. Organic matter promotes the growth and development of crops.

Soil organic matter can enhance plant respiration, increase the permeability of cell membranes, and enhance the absorption of nutrients. At the same time, the vitamins and some biological hormones in the organic matter can promote the growth and development of plants.

    2. Organic matter promotes the formation of soil structure, improves soil physical properties, and improves soil structure

    Humus in organic matter is the main cementing agent of soil aggregates. Soil organic colloid is an indispensable cementing substance for forming water-stable aggregate structure, so it helps cohesive soil to form a good structure, thereby changing the soil pores and water, The air ratio creates a suitable soil tightness. The viscosity of soil organic matter is much smaller than that of clay particles, only a fraction of that of clay particles. On the one hand, it can reduce the viscosity of cohesive soil, reduce farming resistance, and improve farming quality; on the other hand, it can improve the agglomeration of sandy soil and improve its excessively loose state.

   3. Organic matter improves soil's fertility retention capacity and buffer performance.

   The organic colloid in the soil organic matter has a large amount of negative charge, has a strong adsorption capacity, can absorb a large number of cations and water, and its cation exchange capacity and water absorption rate are several times, even dozens of times larger than clay particles, so it can Improve the soil's ability to retain fertilizer and water, and at the same time improve the soil's acid-base buffering properties.

    4. The content of soil organic matter is the key to the survival of soil beneficial microorganisms! It is not only a stable and long-lasting substance with life functions. And it contains almost all kinds of nutrients        needed by crops and microorganisms. Therefore, the soil organic matter is lacking in the soil, the beneficial microorganisms are naturally less, but the harmful organisms are mostly! This is also an important factor for crops to get sick easily!

Three ways to improve soil organic matter

    1. Increase the application of organic fertilizers. The organic matter content of commercial organic fertilizer reaches 45%, which is currently the most used method to supplement soil organic matter. According to relevant data, the utilization rate of chemical fertilizers in our actual production is only 30%-45%. Part of the lost chemical fertilizer is decomposed and released into the atmosphere, part is lost as water and soil, and part is fixed in the soil, which cannot be directly absorbed and used by plants, and it will also cause soil salinization and compaction and other undesirable consequences. When we apply organic fertilizer, its beneficial biological activities can improve the soil structure, increase the soil's ability to retain water and fertilizer, thereby reducing the loss of nutrients. Coupled with the effect of the beneficial organic microorganisms to dissolve phosphorus and potassium, the effective utilization rate of chemical fertilizers can be increased to more than 50%.

    2. Plant green manure crops. The planting of green manure and the rotation of green manure and food crops have always been an important source of fertilizer used to replenish soil organic matter in my country's agricultural production. Green manure has high yield, high organic matter content, rich nutrients, fast decomposition, and rapid formation of humus, which can continuously renew soil humus.
