Determination of the Moisture Content of Forage by Microwave Attenuation

Abstract

The moisture content of forage is an important factor for determining its quality. However, an accurate real-time measurement has been difficult.
In this paper, a new method for determining moisture content of forage is proposed using attenuation of a transmitted microwave.
This method was used to investigate the accuracy of stationary measurements in verifying the moisture content of forage.
Microwave attenuation corresponds to the moisture content and physical properties of materials.
Result showed that using this method for the moisture measurement of forage is effective.
