Determination of water content
WebThe Karl Fischer titration is a moisture determination method specific for water and is suitable for samples with a high water content (titrimetry) and also for those with water content in the ppm range (coulometry). WebSoil water content can be measured on a mass or volume basis. Gravimetric soil water content is the mass of water in the soil, measured as the difference between the moist soil and the soil dried at 105°C, known as the oven-dry weight. Note that gravimetric soil water content is expressed per unit mass of oven-dried soil.
