The depth of soil freezing is related to local climatic conditions, winter weather conditions, snow depth, topography, soil structure, soil moisture, and plant cover. A multi-point soil temperature and humidity recorder was found in cold places. The soil was frozen deep in winter; in warmer places, it was frozen lighter and did not even freeze. In snowy winters, the soil freezes deeper than in snowy winters; in Zedi, the soil is frozen more shallowly; the ploughed fields freeze earlier and deeper than uncultivated soils; moist soils freeze more slowly than dry soils; Soil usually freezes deeper than clay.
Soil freezing has a great influence on the physical properties of the soil. Freezing of the soil can break up the soil particles and increase the voids in the soil. As a result, the soil becomes loose and the soil is easily dispersed into individual particles during cultivation. The freezing of soil has a great influence on plants. As the moisture in the soil voids increases in size when the water is frozen, plant seedlings are often raised upwards and ejected from the soil, thus causing the plants to die. This phenomenon is called freezing or freezing, and most of them are found in heavy, heavy clays. If measures such as soil drainage and straw cover are used to keep the soil warm, real-time monitoring with multi-point soil temperature and humidity recorders using modern instruments can prevent the plants from being damaged.
Multi-point Soil Temperature and Humidity Recorder to Analyze Soil Temperature and Humidity in Soil Freezing
In the cold season, the soil becomes hard because the temperature reaches the freezing point. This phenomenon is called soil freezing. Because the water in the soil is a variety of salt solutions of different concentrations, the soil freezes only when the temperature is below zero degrees Celsius. Therefore, we cannot judge the depth of soil freezing with soil depth at a temperature of zero degrees Celsius. The temperature and humidity of the soil can generally be measured using a multi-point soil temperature and humidity recorder.
