Soil NPK Sensor (Nitrogen-Phosphorus-Potassium) Fertility & Nutrient Measurements Flux Solder Paste Wide Input Voltage Compatibility: OperatesIntroduction: The soil nutrient content can be easily measured using NPK Soil Sensor. Measurement of soil content N (nitrogen), P (phosphorus), and K (potassium) is necessary to determine how much additional nutrient content is to be added to soil to increase crop fertility. The soil fertility is detected using NPK sensors. A major component of soil fertilizer is nitrogen, phosphorus, and potassium. The knowledge of the soil nutrient concentration can
