Background:
Soil moisture refers to soil moisture suitable for plant growth and development. Moisture is the condition of soil moisture. Soil moisture is the degree of soil dryness, that is, the actual water content of soil. Soil moisture affects the growth quality and speed of crops directly. In addition to soil moisture, soil temperature, soil conductivity, soil nitrogen, phosphorus and potassium, soil PH value and other parameters also play a very important role in the growth of crops. We can use soil sensors for online monitoring.
The relationship between soil elements and plants：
Soil temperature has great influence on crop growth, microbial activity, transformation of various nutrients, evaporation and movement of soil water. Within a certain temperature range, the higher the soil temperature, the faster the growth and development of crops. The soil temperature is too low, the microorganism activity is weak, the organic matter is difficult to decompose. Crop root respiration is reduced, resulting in crop nutrient deficiency and slow growth.
Soil conductivity is used to describe soil salinity status. It contains rich information reflecting soil quality and physical properties. For example, soil salinity, moisture, temperature, organic matter content and texture all affect soil conductivity to varying degrees. It is of great significance to obtain soil conductivity values effectively for determining the spatial and temporal distribution differences of various field parameters.
Low or high content of trace elements in soil is not conducive to plant growth. For example, when excessive phosphate fertilizer is applied to the soil, phosphate ions in phosphate fertilizer combine with cations such as calcium and magnesium in the soil to form insoluble phosphate. Not only waste phosphorus fertilizer, but also destroy soil aggregate structure. Cause the soil to harden.Soil ph is one of the important basic properties of soil. It is an index of the process of soil formation and maturation and fertilization. Plants can grow normally over a wide range, but different plants have different pH values for growth.
Soil moisture sensor：
Soil moisture sensor is a high precision, high sensitivity sensor to measure soil moisture. By measuring the dielectric constant of soil, the volume percentage of soil water can be measured. The soil moisture measurement method in line with the current international standard can directly and stably reflect the real moisture content of various soils.
The soil moisture sensor adopts the international new generation FDR measurement method. The accuracy is less than 3%; Electromagnetic non-contact measurement method is adopted. Soil moisture sensor will not drift with time, greatly enhance the stability of the product, prolong the service life.
Soil all in one transmitter：
Jingxun Unsmooth soil integrated sensor (5 in 1 soil sensor) is a soil integrated sensor independently developed by the company. Soil temperature, soil moisture, soil pH value, soil conductivity (EC), soil nitrogen (N), soil phosphorus (P), soil potassium (K) can be monitored simultaneously. The equipment uses the international new generation TDR measurement method, detection accuracy can be up to 3%; The special metal probe greatly prolongs the service life of the product. IP68 protection, can be very good waterproof, dustproof. Metal probe sensitive chip: probe corrosion resistance, electrolytic resistance, salt-alkali corrosion. To ensure that the probe part of the long-term work. Suitable for all kinds of soil, low power consumption, high sensitivity, stable signal.
Soil EC sensor:
Soil EC Sensor adopts the international new generation OF FDR measurement method, the accuracy can be less than 3%; Electromagnetic non-contact measurement method is adopted. The soil conductivity sensor does not drift with time, which greatly improves the stability of the product and prolongs the service life. Epoxy resin vacuum filling, high density epoxy resin between the probe and the main body for high temperature vacuum filling. Can prevent water from entering the main body, sealing performance is better. In addition to the assembly part, we also carry out waterproof and dustproof treatment for the whole body to ensure the long-term operation of components.
