Microwave Dielectric Study of Chemical Fertilizers in Sand Dunes Soil at X-Band

Investigating the Effect of Chemical Fertilizers on Coarse Soils from Sand Dunes Using Microwave Dielectric Study

Abstract

The study of dielectric properties of soil is very important to understand its various aspects including porosity, water holding capacity, quantum of minerals and fertility etc. The coarse dune soil is generally deficient in various minerals and other nutrients. We have studied the effect of chemical fertilizers on coarse soils from sand dunes. Variation in various dielectric parameters like dielectric constant (ε’), dielectric loss (ε’’), Relaxation Time (τ), loss tangent (tanδ) and AC conductivity (σ) with frequency (ν), moisture contents and contents fertilizer are recorded. The experiments are conducted in laboratory using two point method with waveguide techniques at X-band microwave frequency. The results obtained discussed to draw a useful inference.
