Colloidal Content And Related Soil Factors As Indicators Of Site Quality, Irvine T. Haig

Yale School of the Environment Bulletin Series

This paper presents a study of the correlation between soil colloidal content and soil productiveness and hence a measure of the value of colloidal content in determining site quality. The character of this investigation also permitted incidental observation and comment on the relative value of organic matter, soil acidity, and soil type and class as similar measures. The findings are directly applicable to the forest soils of southern Connecticut and, more particularly, to such of these soils as occur commonly in the vicinity of New Haven. Since these soils are typical of the brown, weakly podsolized forest soils of southern …
