Determining the ash content is part of the proximate analysis for nutritional evaluation. The water content is the ratio, expressed as a percentage, of the mass of "pore" or "free" water in a given mass of soil to the mass of the dry soil solids. This method is sometimes used to evaluate the weathering characteristics of clay-shale materials. The water content is also used in expressing the phase relationships of air, water, and. The percent of moisture content at which the transition from solid to semi-solid state takes place is defined as the shrinkage limit (SL).
