Soil deterioration refers to the destruction of the soil's agglomerative structure, which is good for both aeration and water and fertilizer retention, and also for drought resistance.
However, soil granular structure is particularly unstable and is easily damaged by the external environment.
For example, watering too hard or too much, or applying unrotted organic fertilizers, spraying some chemical fungicides, especially herbicides, can damage the soil granular structure.
If the soil granular structure is damaged, the small molecules that make up it do not exist, the soil becomes a surface, piled up to a piece, it is easy to cause soil consolidation.
Many farmers think that the soil is simply hardened, crop roots can not be rooted down, but in fact, because the physical structure of the soil has been damaged, resulting in the slab.
