Soil nutrient sensor plays an important role in agriculture. Now agriculture is developing in the direction of science and refinement, and the requirements for crop planting are becoming more and more strict.Using advanced sensing instruments to measure and obtain reliable soil nutrient information. Managers can carry out reasonable soil testing formula fertilization according to these information. More in line with the law of plant growth and the development goal of smart agriculture.
The application of soil sensors in vegetable planting allows producers to discover what elements are lacking in vegetable growth and adapt them to local conditions. This is an important strategy of scientific fertilization in vegetable production. The application of soil sensor can effectively reduce the waste of chemical fertilizer and soil pollution caused by chemical fertilizer. Both economic and environmental protection, for the healthy development of China’s agriculture has made a great contribution.
Soil is also important for plants. The quality of soil is a direct reflection of the quality of plants. Take soil pH, for example. If the soil is acidic or alkaline, the availability of soil nutrients will be reduced to varying degrees.
It is difficult to form a good soil structure and seriously inhibit the activity of soil microorganisms, thus affecting the growth and development of various crops. Therefore, soil pH plays a key role in planting. Here is the knowledge of soil sensor products.
01, soil pH sensor
The new Pratt & Whitney pH soil sensor is used to determine the content of pH in the soil. It consists of a numerically indicated ammeter, a metal sensor and a function value switching device. Metal sensor as the core of the hardware system. The metal sensor is in contact with the soil. And the current generated by the REDOX reaction in the chemical reaction corresponds to different PH values.
02, soil nitrogen, phosphorus and potassium sensor
Nitrogen, phosphorus and potassium sensors mainly analyze the chemical substances in soil and fertilizer. And can quickly measure the contents of phosphorus, potassium, organic matter, calcium and magnesium and other trace elements in soil. Through the sensor and the corresponding soil nutrient index.We can judge the nutrient content of the land, so as to make better use of the nutrients contained in the soil itself and timely supplement the insufficient elements.
03, soil temperature and humidity sensor
Soil nutrient sensor plays an important role in agriculture.The new Puhui soil temperature and humidity sensor is composed of soil temperature sensor and soil humidity sensor. To measure the soil temperature sensor, simply insert the probe into the soil and the display will show the current soil moisture.
In addition, the use of soil temperature and humidity monitoring system. When the soil temperature and humidity is high, can start the exhaust fan or window, reduce the soil temperature and humidity. When the normal value, the fan or window can be closed; Reduce soil temperature and humidity to normal state.
Soil temperature and humidity sensors have been widely used in water-saving agricultural irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil rapid measurement and other fields. Soil temperature and humidity sensor can easily grasp the change of soil temperature and humidity, so as to better complete the help to crop growth.
