Study on Principles and Technical Methods of Soil Moisture Measurement

Soil moisture plays an important role in crop growth and microbial activities, and has a very wide range of effects in agricultural, engineering, and ecological fields. Soil moisture content is one of the important parameters of soil physical and chemical characteristics, and it is also one of the important indicators for formulating a reasonable irrigation system, optimizing water resources management, and ensuring the safety of soil engineering construction. This paper introduces several widely used soil moisture measurement methods and their measurement principles at home and abroad, and analyzes their advantages and disadvantages. The main problems and development trends in soil moisture determination methods were put forward.
