Soil Moisture Monitoring for Agricultural and Environmental Purposes

Soil moisture monitoring is crucial for agricultural production, water resource management, flood warning and drought assessment. Soil moisture research has been carried out at home and abroad.
For example, in the mid-to-high altitude areas of Switzerland, the SOMOMOUNT network has been established to monitor soil moisture, which is achieved through setup and initial results.
The International Soil Moisture Network provides a data hosting facility for soil moisture measurements on a global scale and has served earth system science for more than ten years.
The AQUI soil moisture network has been established in southwestern France for satellite microwave remote sensing verification, covering various scenarios such as farmland and small watersheds.
In Germany, a dense soil moisture observation network such as STH-net has been established for soil moisture monitoring from field to hillslope scale to support hydrological models and environmental research.
The Met Office of the United Kingdom and Plymouth Marine Laboratory jointly launched the COSMOS-UK project, aiming to provide nationwide soil moisture and hydrometeorological data to support environmental science.
On the Qinghai-Tibet Plateau in China, the Tibet-Observation Station has been established. This is a multi-scale soil moisture and freeze-thaw monitoring network used to quantify the uncertainty of coarse-resolution satellite and model products.
The European Union Climate Change Initiative supports the soil moisture data record project based on satellite data, aiming to provide long-term and continuous soil moisture data to support climate research.
The Tubular Soil Moisture Monitor is based on the principle of dielectric constant and can dynamically observe the soil moisture content of different soil layers. It integrates soil temperature, moisture and electrical conductivity monitoring and is suitable for fields such as smart agriculture. Product parameters include a soil temperature measurement range of -30~70°C, soil moisture of 0~100%, soil electrical conductivity of 0~20000us/cm, and the communication method is 485 Modbus RTU protocol.
