Soil Moisture Sensors and Soil Moisture Monitoring
Soil moisture, also called soil moisture, is an important indicator for studying agricultural drought and crop drought. Moisture is not only necessary for the formation of carbohydrates by photosynthesis in plants, but also an indispensable constituent of the plant body itself. Soil moisture is the main source of water absorption by plants, an indispensable medium for chemical, biological and physical processes within the soil, and an important factor in soil fertility. Therefore, frequent soil moisture condition measurement and mastering soil moisture change pattern are of great significance for both real-time service and theoretical research of agricultural production.
Soil moisture sensor use method and attention
In addition to the equipment itself, the use of soil moisture sensors should also consider areas with large differences in geographical environmental factors such as altitude, terrain topography, and soil texture.
①There are differences in terrain height, and there are many sloping plots at the bottom of ditches and hilltops, and there are large differences in climate conditions, planting systems and irrigation conditions in a small area.
②The soil level at the burial site contains more stones, more stones and less soil make the soil volume water content naturally low, and the soil relative humidity is also low, which has a great impact on the actual measurement and thus leads to the occurrence of data errors.
③ part of the soil moisture sensor buried point soil is less or soil texture is not uniform, etc., in the stone block more similar impact, will also directly affect the monitoring of soil volume moisture content.
④Inappropriate installation method: there is a gap between the detection instrument and the soil, which will also lead to a large error between the artificial comparison observation data and the instrument observation data.
