dc.description.abstract	The paper presents a novel approach for determining soil nutrient content using Radio Frequency signals. The study is conducted to obtain the frequency response of urea. A shielded cell is designed for obtaining the frequency response of urea solution. A signal generator and a spectrum analyzer are used to obtain the RF responses of urea with different concentrations in the range of 10MHz - 4.4GHz. It is observed that at certain frequencies, the response of urea to RF changes in accordance with the changes in the concentration of urea and at other frequencies, it has a flat response. These results can be used for the prediction of unknown concentration of urea based on a multivariate system. The variation in the RF response can be fed to a multivariate system analyzer to estimate the concentration of urea in an unknown sample.	en_US
