ABSTRACT
This paper reports the experimental results of the dielectric behaviour of mixture of different types of fertilizers and soil at L, S and C frequency bands. A simple and rapid measurement method using microwave free-space transmission technique is used for measuring the dielectric constant. The variations in dielectric constant of soil with different concentration of various fertilizers like Boric Acid, NPK, Potash and Urea are studied extensively. Measurement has been performed using Vector Network Analyzer (VNA) and antenna/soil sample holder. The sample-mixtures are prepared by mixing different fertilizers in soil according to the statistics provided by the Department of Agriculture.
