Abstract
A laboratory study was conducted on samples of Bt horizons of three Hapludults to determine the effects of time of extraction and reextraction freezing and thawing, or drying, rewetting, and incubating. The relationship between electrical conductivity (EC) and ionic strength (I) also was studied. Significant changes in soil solution composition were found as centrifugation solution extractions. Also EC can provide a good estimate of I of soil solutions. Soil solution composition was substantially altered by preextraction drying-rewetting or freezing-thawing. Neither of the methods studied here provide a good means of storing soil samples prior to soil solution extraction. -from Author
