Effects of Combined Conservation Practices on Soil and Water Quality in the Central Mississippi River Basin

The Central Claypan Area is dominated by high runoff potential claypan soils, and soil and water quality degradation within the northeastern Missouri portion of the region has been well documented over the last 20 years. Conventional cultivation of claypan soils leads to soil and water quality degradation because of high runoff and associated soil erosion. The objective of this study was to compare runoff water quality from the two management systems, based on flow and load duration curves, cumulative distribution functions, and conclusions from replicated plot studies.
