Bulletin No. 170 - A Study Of Methods Of Determining Soil Alkali, D. W. Pittman

UAES Bulletins

There is a great lack of uniformity in the methods of testing soils for alkali salts and in the forms of expressing the results in a way that will show the relative toxicity of the salts. This has been pointed out by numerous investigators and has been shown to complicate the determinations so much that the results of different investigators are hardly comparable. It is of further disadvantage in that the toxic limits of an alkali as worked out by one system of analysis are often difficultly applicable to a soil that has been tested by another system. However, it …
