Soil Drying by Microwave Oven Semantic Scholar

An investigation of the usefulness of the microwave oven for water content determination and for drying of soil before testing was performed. Soils ranging from highly plastic clays to clean sand were used. The influencesof initial water content, amount of soil, and soil type on the drying time were investigated. Differences between water content determined using a microwave oven …

Water is the first component of the soil to heat and evaporate. If the sample is dry and microwave drying continues, the soil temperature will increase and oxidize organic matter. This will bias your results. If you are using a conventional drying oven, place samples in the oven at 105 degree centigrade (220 F) for 24 hours.
