Title:	LANDUSE AND SOIL ORGANIC CARBON VARIABILITY IN THE OLD WOMAN CREEK WATERSHED OF NORTH CENTRAL OHIO
Author:	Kroll, Jeffrey T.
Description:	This study investigated the variability of soil organic carbon within the Old Woman Creek watershed and the influence of landuse, soil texture, geomorphic surface and depth on SOC variability. Soil samples were collected at 0-30cm and 30-60cm depths in forest, pasture, conservation tillage and conventional tillage sites in both the Lake Plain and Till Plain. The Lake Plain had higher SOC than the Till Plain, and geomorphic surface had a greater affect at the 30-60cm depth than the 0-30cm depth. SOC was higher at the 0-30cm depth than the 30-60cm depth. Forest and pasture landuses had higher SOC than conservation and conventional tillage landuses. Conventional tillage had higher SOC than conservation tillage. Linear regression models and soil survey data were used to extrapolate SOC data to the watershed. Linear regression models could be useful estimators of SOC when used with site-specific data.
