ている。±The fact that the soil has a stable aggregate structure and has good water permeability and air permeability is not only an important factor for growing crops, regardless of whether it is field soil or paddy soil, but also from the perspective of improving the efficiency of agricultural work. This is also an extremely important factor. However, heavy clay soil lacks these factors, making it impossible or poor to grow crops, and has become a major agricultural problem in the current era, where there are calls for expanding the scale of agricultural operations and improving self-sufficiency. .
