Soil Moisture Tester For the determination of soil moisture in two different indicators, the relationship between soil moisture content and soil water suction is very close. Sites need to be set up, including specific site information, site additions, deletions, and movements. After the system completes these settings, it is possible to perform the functions of the system. In irrigation production, soil water content is generally used to indicate soil moisture content. Soil water suction is affected by temperature, so it should be kept on a certain date and time at the time of measurement. This will reduce the influence of temperature fluctuation factors. Soil moisture tester was used to measure the soil at 0:20cm and 20-40cm below the drip irrigation, under the membrane and between the membranes at 10:00 on the first, third, fifth and seventh days after the first irrigation in the cotton seedling stage. Water potential, soil sampling with earth-drill, collected in aluminum box, dried by soil moisture content determination, the results show that the relative soil moisture content and soil water suction is inversely proportional to the soil relative water content is greater, the soil water suction is smaller; The greater the relative soil moisture content, the lower the soil water suction.
Soil Moisture Tester For different types of soil, the same soil moisture content is not the same for the plant's water absorption capacity. Therefore, simply judging whether or not to use irrigation based on changes in soil moisture content is not reasonable. It can collect soil moisture information in real time to realize the positioning, timing, and appropriate water supply for farmland irrigation. The instrument is a high-precision, high-efficiency and reliable soil moisture information acquisition instrument.
