Abstract: Changes in saturation extract composition caused by microbial production of carbon dioxide were followed by collecting and analyzing fractions of the saturation extracts from Yolo fine sandy loam and eight salt-affected soils. Bicarbonate and cation concentrations increased in the extracts of all but one soil during the course of extraction. Addition of thymol to the soil paste at the time of preparation is recommended to reduce the effects of microbial activity on composition of the saturation extract.
