Soil moisture content and soil nutrient content are two basic parameters of soil properties. The timely mastering and understanding of these two soil parameters is conducive to water-saving irrigation of soil and guidance of fertilization schemes in soil. Because from the country's investigation and research, without knowing the local nutrient content of the soil, long-term blind fertilization, the soil nutrients lose their balance, which wastes the input of fertilizer, reduces the utilization of crop-degree fertilizer, and hinders the high yield of fertilizers on crops. The role that quality should play. Due to the reduction of organic matter content, it also caused a misalignment of soil micro-organisms, which is an increase in the incidence of crop pests and diseases. Therefore, the timely and effective measurement of soil nutrients and soil moisture has far-reaching effects on agricultural operations.
The soil nutrient tester can detect available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, soil pH, and soil salinity in soil, plants, chemical fertilizers, and biological fertilizers. Therefore, many nutrient contents equivalent to soil can be measured by a soil nutrient tester. In addition, the TPY-6PC soil nutrient tester is also equipped with an intelligent formula fertilization software system, which stores the nutrients required for the growth and development of 70 kinds of crops. Moreover, the soil nutrient tester is based on China's national conditions and some fertilization standards, and then according to some local conditions, combined with the instrument test results, to guide the fertilization of crops. The soil nutrient tester can store up to 1,000 sets of data, record the time, location and all kinds of nutrient results of the test samples. The data can be read out at any time for easy comparison.
Soil fertility is on the one hand, and soil moisture content is also very important. The amount of soil moisture may even affect the crop's absorption of nutrients. Soil moisture can be measured by a soil moisture detector. Of course, in some areas due to severe drought conditions, such as China's northwest region, a large area of ​​farmland operations in the southwest, often equipped with soil moisture and drought monitoring system, the biggest difference between this system and the soil moisture detector is that it can track records Measure the annual moisture content and record it on the inside of the instrument for convenient viewing. The soil moisture detector produced by Top in Zhejiang adds GPS positioning function. While measuring the soil moisture content, it can also measure the exact information of the measured point, and then store the position information, soil moisture, number of groups and other information, so it can reflect Spatial differences in soil moisture. The soil moisture detector is not only conducive to the implementation of water-saving irrigation, but also can provide accurate water supply guidance. In addition, suitable soil moisture is more conducive to the maintenance of soil nutrients, and the absorption of nutrients by crops.
