Why are nitrogen, phosphorus and potassium important to the soil?

The effect of nitrogen, phosphorus and potassium in soil on crops:

A correct understanding of how vegetables and crops use nitrogen, phosphorus, and potassium is essential to increase crop yields. In its natural form, most soils in the world are equipped with enough elements necessary for plant growth. However, in the world of agricultural production, the soil is depleted of these basic ingredients. Biological soil amendments are needed so that crops can maintain yields. So what is the effect of N, P, and K? Plants will end their lives if they leave them, and how do soil sensors for agriculture monitor them?

Nitrogen is an integral part of all proteins and one of the main chemical elements required for plant growth and photosynthesis. Crops absorb nitrogen through roots that absorb ammonium or nitrate. Then use nitrogen as a building block to produce protein in the form of an enzyme.


Phosphorus is essential for strong growth. Sufficient phosphorus in the soil can lead to slow-growing rotating crops. After phosphorus is combined with water, it is decomposed into ions that can be absorbed by plant roots, and it is used for photosynthesis and energy/nutrient transportation.


Potassium is the third of the three elements of healthy soil nutrition. Can greatly increase crop yields. It helps the absorption and retention of water and also encourages strong roots. Many crops depend on abundant potassium supplies. Therefore, it is necessary to rely on fertilizers and soil improvement to supplement the potassium in the soil. Agricultural products containing potassium are water soluble, allowing crops to absorb it through nutrient-rich soil.

Monitoring of soil nitrogen, phosphorus and potassium:

Nitrogen, phosphorus and potassium are vital to soil fertility. Crops cannot leave nutrients such as nitrogen, phosphorus and potassium, so how do we monitor the content of nitrogen, phosphorus and potassium in the soil? We can use the soil nitrogen, phosphorus and potassium detector in soil sensors for agriculture. The soil nutrient detector is used to monitor the content of nitrogen, phosphorus and potassium in the soil, and it can also be tested with three-in-one elements. The soil nutrient detector can not only detect the content of nitrogen, phosphorus and potassium. It can also monitor other trace elements to ensure the supply of the elements needed for the normal growth of plants.
