Fertilizers is the food of crops and the material basis for increasing production. There is a saying in our country that “no dung on the land is tantamount to foolishness”. The fertilizers commonly used in agriculture are nitrogen, phosphorus, and potassium. Nitrogen fertilizer is a chemical fertilizer with nitrogen nutrient elements as the main component. Including ammonium bicarbonate, urea, nitramine, ammonia, ammonium chloride, ammonium sulfate, etc. Phosphate fertilizer is a chemical fertilizer whose main component is phosphorus nutrient elements. Including ordinary calcium phosphate, calcium magnesium phosphate, etc. Potash fertilizer is a chemical fertilizer with potassium nutrients as the main ingredient. At present, there are not many applications, and the main varieties are potassium chloride, potassium sulfate, potassium nitrate and so on.
The soil nitrogen, phosphorus and potassium rapid tester adopts highly sensitive probes to measure various types of soil. It can be plugged and measured without waiting. It is convenient to carry and shortens the time and cost. The soil nitrogen, phosphorus and potassium tester can provide important help for crop fertilization. , To help farmers detect the basic content of nitrogen, phosphorus and potassium in cultivated land, and formulate a reasonable and complete fertilization program on this basis. In order to solve the difficulties in the detection of soil nitrogen, phosphorus and potassium, Jingxunchangtong has specially developed soil nitrogen, phosphorus and potassium sensors.
Characteristics of soil nitrogen, phosphorus and potassium sensors:
(1) The sensor has a compact design, easy to carry, simple installation, operation and maintenance.
(2) The structure design is reasonable, and the stainless steel probe ensures the service life.
(3) The soil quality is less affected and the application area is wide.
(4) The measurement accuracy is high, the performance is reliable, and the normal operation is ensured.
(5) Fast response speed and high data transmission efficiency.
To plant a good land, it is inseparable from the monitoring and analysis of soil properties, especially soil organic matter and fertility. If we can monitor the nitrogen, phosphorus and potassium content of the soil in real time online, we can indeed better understand the relationship between soil fertility and crop growth. It can also be more convenient to fertilize and improve agricultural production efficiency. Therefore, the bidding documents of many smart agriculture projects frequently appear in the procurement requirements of “sensors capable of measuring soil nitrogen, phosphorus and potassium online”.
