The common methods and steps for measuring soil moisture content are: Soil sampling accuracy. Place the aluminum box in a plastic bag to avoid sunlight exposure and send it to the room for weighing. With the development of agricultural scientific instruments, the soil moisture and drought management system of high-tech products in line with national standards can not only monitor soil moisture in real time, but also monitor soil water potential, temperature and conductivity according to user requirements, and supporting software can be provided. According to the user's need to flexibly set the sampling period and storage period of the public opinion parameters, patrol measurement and recall data, and analysis data, a single system can implement simultaneous six-point simultaneous detection of multiple monitoring points.

1, sampling period: sampling period according to the provisions of 4 to 10 months every month to take a sample every 1 time, every 1 reported that the interval between the 10d.
2. Sampling instrument: Sampling instrument should select one of the commonly used ones, and the observation instrument should maintain relative stability. It is not possible to change the observation instrument, and pay attention to maintenance and maintenance.
3, soil samples taken: soil samples should be repeated at the same location in different depths of 3 times, each time about 30-50g. After the soil sample is loaded into the box, the residual clay in the net box shall be removed. After the soil sample is packed in the aluminum box, the lid is tightly closed and the dirt outside the box is wiped with a cloth to ensure the
4. Soil Sample Weighing: The soil sample should be weighed with a 1% balance. All soil samples must be taken and weighed once, and they must not be separated or discarded. The weighing method is the same as the weighing of sediment.
5, soil sample drying: soil sample drying, remove the lid, placed in the oven at 10 ~ 110 °C, constant temperature 6 ~ 8h. Turn off the oven power. After cooling, remove the lid of the box and place it in a desiccator. Cool to normal temperature and weigh it.
