Soil moisture monitoring directly affects the growth quality and speed of crops. The quantity of soil moisture suitable for plant growth and development. Moisture content refers to the moisture content of soil. Soil moisture is the dry and wet degree of soil, that is, the actual water content of soil.

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 crop growth.

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 crop growth.

Soil moisture sensor

Soil moisture sensor is a high precision and high sensitivity sensor for measuring soil moisture. By measuring the dielectric constant of soil, the volume percentage of soil moisture can be measured, which conforms to the current international standard of soil moisture measurement method, and can directly and stably reflect the real moisture content of various soils.

Soil three-in-one sensor

Soil three-in-one sensor is an important tool to observe and study the occurrence, evolution, improvement and water and salt dynamics of saline soil. By measuring the dielectric constant of soil, the true moisture content of soil can be directly and stably reflected. The volume percentage of soil moisture that can be measured is the soil moisture measurement method that conforms to the current international standard.

Soil PH sensor

Soil PH sensor, for measuring soil PH value The transmitter has high accuracy, fast response, stable output, suitable for all kinds of soil. It can be buried in soil for a long time, resistant to long-term electrolysis, corrosion resistance, vacuum sealing, completely waterproof. It can be widely used in soil PH detection, fine agriculture, forestry, geological exploration, plant cultivation, water conservancy, environmental protection and other fields of pH measurement.

Soil parameter speedometer

The soil parameter speedometer can accurately detect and display a variety of components in the soil in real time, such as soil temperature and humidity, soil conductivity, soil nitrogen, phosphorus and potassium, etc., through the detection data to improve the soil, achieve the purpose of monitoring the supply of plant nutrients, so that crops in the best living environment, so as to improve the yield.

Tube type soil moisture monitor

Tubular soil moisture monitor is a kind of sensor based on dielectric constant principle. It can dynamically observe the soil moisture content and temperature at different levels. This detector can detect the soil temperature and humidity at the lowest level of 3, and the highest level of 5, which can quickly and comprehensively understand the soil moisture information.

Methods of measurement

Soil moisture sensor, soil three-in-one sensor, soil PH sensor measurement method

(1) Quick test method

Select the appropriate measuring site, avoid stones, ensure that the needle will not encounter hard objects, according to the required depth of measurement to put aside the surface soil, maintain the original tightness of the soil below, hold the sensor vertically inserted into the soil, do not shake around when inserted, a small range of measurement point is recommended to measure the average number of times.

(2) Buried ground survey method

Dig a pit with a diameter of more than 20cm vertically, insert the sensor steel needle horizontally into the wall of the pit at the given depth according to the measurement needs, fill the pit firmly, and stabilize it for a period of time, then the continuous measurement and recording can be carried out for several days, months or even longer.

Soil parameter tachometer

Long press the open key, vertically insert the sensor alloy probe into the soil at the place where measurement is required, and then press the open key to start measurement.

 

Tubular soil moisture monitor

The tubular soil moisture monitor adopts a layered observation structure, with a temperature observation point on the ground and a soil temperature and humidity measurement point every 10cm in the underground soil to observe the soil temperature and humidity within the corresponding range.

 

 

Multi-layer soil parameter monitor

Dig a pit with a diameter of more than 20cm vertically, insert the sensor steel needle horizontally into the wall of the pit at a given depth, fill the pit tightly, and stabilize it for a period of time, so that continuous measurement and recording can be carried out for several days, months or even longer
