How to Improve Soil Slumping

Causes of soil slumping

Disruption of the soil agglomerate structure

One of the physical structures of soil is called "soil agglomeration", which means that the soil is made up of small clumps, like earthworm dung. A good soil granular structure is aerated, retains water and fertilizer, and is also drought resistant.

Soil grain structure is an important indicator of soil fertility. The destruction of soil grain structure leads to the reduction of soil water and fertilizer retention capacity and permeability, resulting in soil consolidation; the content of organic matter is an important indicator of soil fertility and grain structure, and the reduction of organic matter leads to soil consolidation.

Soil organic matter is an important component of soil bulk structure. The decomposition of soil organic matter is achieved by the activity of microorganisms. Long-term single application of chemical fertilizers, humus can not be replenished in a timely manner, not only cause soil slumping, but also may crack. Chemical fertilizers cause soil slumping because only cations or anions in chemical fertilizers are elements needed by plants, and plants unilaterally choose to absorb the useful ions, causing soil acidification or salinization. The destruction of soil granular structure causes soil water and fertilizer retention capacity and permeability to decrease, resulting in soil slumping.

Soil agglomerate structure is particularly unstable and susceptible to damage by the external environment, including human intervention. For example, watering too often, watering too much, or applying unrotted organic fertilizers, spraying some chemical fungicides, especially herbicides, can damage the soil granular structure.

If the granular structure is damaged, the small molecules that make up it no longer exist, the soil becomes dough-like, piled up to a piece, many farmers think that the soil is simply hardened, in fact, because the physical structure of the soil has been damaged, which caused the slating.

How to improve soil slumping

When fertilizers are used when the soil is caked, soil salinization and acidification become more severe and the biological properties deteriorate. When considering soil improvement, it is important to make a combination of improvements.

1, Improve soil pH and saline soil. Soil is improved by improving the pH of the soil to improve the agglomeration structure of the soil and increase the number of beneficial microorganisms.

2, Watering follow the principle of "watering is watering thoroughly, not dry, not watering". Watering should not be too frequent. If you water too often, it is advisable to cause slabbing.

3, Scientific fertilization, scientific use of drugs, do not increase the use of drugs and fertilizers.

4, The scientific use of biological fertilizer to govern the soil. Biological bacterial fertilizer, which is conducive to improving the soil structure and revitalizing the soil.
