Soil Water Content by Microwave Drying: A Routing Procedure
1981
Gee, G. W. | Dodson, M. E.
A routine procedure was established for determining soil water content by microwave drying. The procedure requires small, 20-gram soil samples heated for a 20-min period at full power (600 to 650 W) in a household-type microwave oven. Using this procedure, consistent agreement (within 0.5 wt%) was obtained between microwave and electric oven drying for soil materials ranging from quartz sands to fine silts and clays, with water contents ranging from air-dry to saturation and with organic matter ranging from 0 to > 20 wt%.
