Determination of soil moisture status, mastering the changing law of soil moisture

Soil moisture, also known as soil moisture, is an important indicator for studying agricultural drought and crop drought.

Water is not only an essential substance for plant photosynthesis to form carbohydrates, but also an indispensable constituent of the plant itself.

Soil moisture is the main source of water absorption by plants, an indispensable medium for chemical, biological and physical processes in the soil, and an important factor for soil fertility.

Therefore, it is of great significance for the real-time service of agricultural production and theoretical research to measure the soil moisture status frequently and master the change law of soil moisture.
