6. LABORATORY METHODS FOR ANALYSING GYPSIFEROUS SOILS

The presence of gypsum limits dispersion of soil colloids. In the traditional procedures for particle-size analysis of gypsiferous soils, gypsum present in small amounts is leached by using distilled water (Baldwin et al. 1938, Barzanji 1973). Solutions of strong electrolytes can be used to increase the solubility of gypsum and shorten the leaching time (Abrukova and Isayev 1983, Agboola and ...
