Application of Soil Testing Sensors in Agriculture: A Review

The soil whose main role is to provide nutrients in the process of plant growth is the foundation and an important part of agriculture. Soil testing is an important step for increasing agricultural production and raising farm income. Traditional soil testing methods rely on chemical processes carried out in a laboratory. Sensors play a significant role in agriculture by direct measurement of soil chemistry through tests such as pH, moisture, nutrient content, humidity and temperature. The results of soil tests are important to get high yield with good quality produce. ISE (Ion Selective Electrode) and ISEFT (ion-sensitive field effect transistor) sensors have also been used to detect the uptake of ions by plants.
