This document specifies laboratory methods for determination of the soil water-retention characteristic.

This document specifies laboratory methods for determination of the soil water-retention characteristic.This document applies only to measurements of the drying or desorption curve.Four methods are described to cover the complete range of soil water pressures as follows: method using sand, kaolin or ceramic suction tables for determination of matric pressures from 0ÂkPa to â??50ÂkPa; method using a porous plate and burette apparatus for determination of matric pressures from 0ÂkPa to â??20ÂkPa; method using a pressurized gas and a pressure plate extractor for determination of matric pressures from â??5ÂkPa to â??1Â500ÂkPa; method using a pressurized gas and pressure membrane cells for determination of matric pressures from â??33ÂkPa to â??1Â500ÂkPa. Guidelines are given to select the most suitable method in a particular case.
