Abstract: This project is aimed at determining the fertility of soil in terms of three prominent factors (nitrogen, phosphorous, potassium) present in soil. Accordingly readings are obtained and calibrated to obtain deficiency of these minerals in the sample soil. These results will be useful in improvement in quality of soil.
