Brochure, flyer, fact-sheetStandard operating procedure for soil moisture content by gravimetric method 2023
Also available in:
No results found.Soil moisture content is one of the fundamental properties used in making decisions related to soil management, such as land preparation, design of irrigation and drainage systems, construction, and risk management. Analytically, determination of air-dry moisture content (i.e. remaining moisture in soil, dried for laboratory analysis) is important, since it is used to express the results of other tests (e.g. carbon, nitrogen, phosphorus, etc.) on an oven-dry basis. Soil moisture content analyzed by the gravimetric method has low operational difficulty and can be used for multiple purposes. -
