Abstract: The goal of accurately mapping of soil properties is to analyze various primary nutrients (NPK) in the soil. In this paper we discussed spectroscopy and conductivity measurement technique for primary nutrients determination. In the conductivity measurement, we observed that conductivity of the soil depends on the concentration of primary nutrients. The results are verified for Potassium nutrient by conductivity setup. In spectroscopy method, results are tested for potassium nutrient. Experimentally it has been found that maximum absorbance is at 260 nm and as concentration of the Potassium increases the absolute value of absorbance also increases. The results are helpful in analyzing primary nutrients in the soil.
