Abstract
The soil is saturated with LiCl solution buffered at pH 8.2 with LiOAc, followed immediately by leaching with Ca(OAc)2 at pH 8.2. Na, K, Ca, Mg and Li are determined in the extracts by direct flame photometry and complexometry. The need for washing the soil is eliminated by assaying the remaining excess salts as C1. Soluble ions are determined on a separate sample. The method can be used on non-saline or CO3-free soils by adjusting the saturating and extracting solutions to pH 7.
