Abstract

This paper reports experimental results which have been carried out for understanding the behavior of dielectrics in the form of mixer of fertilizers and water content at wide frequency range in different temperatures. A simple and rapid measurement (reflection method) was used in determining the dielectric response at microwave frequency. The dielectric constant and loss have been measured in frequency range from 1 to 40 GHz with different temperature according to environment. The measurement procedure has been performed by dielectric probe kit using 50 GHz Performance Network Analyzer (PNA). The samples were prepared by mixing different fertilizers in water according to the Department of Agriculture. The different fertilizers (urea and diammonium phosphate) were taken from the market. The experimental work shows the dielectric behavior of solution of fertilizers and water in temperatures. The amount of water and fertilizers content were taken according to the Department of Agriculture.

Keywords: Dielectric constant, dielectric loss, reflection, dielectric probe kit.
