Lyrical refers to the situation of the land. In dry farming areas in northern China, the condition of soil moisture is usually called soil moisture. Soil moisture content is the moisture content of the soil, and the soil moisture content can be expressed as the percentage of soil moisture in dry soil weight: soil water content = water weight/dry soil weight × 100%. It is also possible to express the relative moisture content such as the percentage of soil moisture that corresponds to the amount of water in the field, or the percentage relative to the amount of saturated water. It is also called the degree of dry and wet soil. According to the relative humidity of soil, it can be known that the extent of soil moisture, but also how much water can maintain, has reference value in irrigation. Soil moisture affects field climate, soil aeration and nutrient decomposition, and is one of the important conditions for soil microbial activity and crop growth and development. Soil moisture is affected by the conditions of the atmosphere, soil, and vegetation.
