Soil moisture monitoring is a fundamental and quite important task in agricultural production management, with the core goal of accurately grasping the moisture status in the soil to provide a basis for agricultural production decisions. Among them, moisture deficiency, as a specific manifestation of insufficient soil moisture, directly affects the growth and development of crops. Therefore, accurate monitoring and evaluation of soil moisture are crucial.
Soil relative humidity is an important indicator for evaluating agricultural drought and the degree of moisture deficiency. By dividing the numerical range of soil relative humidity, different levels of moisture deficiency can be clarified. When the soil relative humidity is in a relatively high range, it indicates that the soil has mild moisture deficiency. At this time, crops may experience slight insufficient water supply, and the impact on growth is relatively small. When the value is in the middle range, it is moderate moisture deficiency, and crop growth will be significantly inhibited, with leaves possibly showing wilting and other phenomena. When the value is in a lower range, it is severe moisture deficiency. In this case, soil moisture is severely lacking, which will greatly hinder the normal physiological activities of crops and may even lead to reduced yield or total crop failure.
As the core tool for implementing monitoring work, the Automatic Soil Monitoring System is equipped with a series of professional equipment and advanced technical means. These devices can penetrate different depths of the soil, collect soil moisture-related data in real-time, and through specific technical processing, convert them into soil relative humidity information that can be directly used for analysis. The monitoring station does not conduct one-time monitoring but carries out continuous observation and recording work. This makes it possible to fully grasp the dynamic changes in soil moisture status, including changes in different periods of the day and long-term trends.
Using these continuous and accurate monitoring data, the monitoring station can timely and accurately determine the current degree of soil moisture deficiency. These data are of great significance to all aspects of agricultural production. For farmers, based on these data, they can scientifically arrange the irrigation time and amount, avoid water waste caused by blind irrigation, and ensure that crops receive appropriate water supply. For agricultural management departments, these data are important references for formulating regional agricultural drought resistance strategies and guiding the layout of agricultural production, which helps to improve the risk resistance of agricultural production, ensure the stable development of agricultural production, and ultimately achieve high-quality and high-yield crops.
