Why can't we use the plow to plow

One is the large soil moisture loss after plowing, and the exposed surface is eroded by wind and water; the second is the formation of the plow bottom, which affects the soil water storage capacity and the growth and development of the crop root system; the third is the soil aggregate structure is destroyed; the fourth is the clay after the plowing The organic matter content of the surface layer decreases, which leads to soil compaction. Fifth, the surface soil is finely broken and exposed after plowing, which is easy to raise dust and cause atmospheric pollution.
