Instant Detection of Macronutrients Nitrogen, Phosphorous and Potassium using Analog pH Sensor
Nishad Kumbhare,  S. R. Kumbhar
The customised sensor-based analysis may provide the precise data quickly rather than mundane and traditional methods, which are generalized and not to the targeted are or specific area. Quickly and accurately soil data can be analysed by the precise agriculture practice through electronic systems rather than traditional geochemical analysis. Also, unsystematic use of fertilizers may lead to ground water pollution, hence nutrients management, balanced plant nutrition, which are ecological alternatives for fertilizers. This research work facilitates the exploration of major macronutrients – Nitrogen (N), Phosphorous (P) and Potassium (K) by the measured value of pH from pH sensor with suitable conversion, signal conditioning and embedded programming. The macronutrients present in soil are displayed on LCD module interfaced with Microchip PIC16F877A microcontroller. Hence, by this method it is possible measure the concentration of NPK and also this method prevents the overfeeding of nutrients through fertilizers.
