SOIL MOISTURE DETERMINATION USING MICROWAVE RADIATION

A simplified method for soil moisture determination using ordinary filter paper folded into cups for holding the sample is described. The microwave source was a General Electric Model Jet 90 microwave oven rated to deliver 625 W (high power at a wave length of 2450 MHz. Details of the Materials and methods are given and the results are discussed. This method was compared with a 1974 method (by Miller, Smith and Biggar) using a microwave oven, special beakers, and in some cases, long times for heating. Both methods gave essentially similar results with heavy-textured and light-textured soils. However, the Miller, Smith and Biggar method could not be used for montmorillonite and kaolinite clays. The use of the microwave treatment to determine soil moisture offers the advantage of speed.
