Design of Soil Nutrient System for Indian Crops

Abstract

To increase the fertility of crop it is important to determine what is requiring for crop. For any crop 12 nutrients are required. We have developed NPK and PH sensor for soil testing. This will determine the PH and NPK value of the soil .In this paper color sensor with fiber optic is developed for determining the NPK components of soil. To know the soil pH we used a pH sensor.
