Adapting rusle2 for Ontario

Authors: Mckague, K
Description: In the late 1970’s and early 1980’s, Ontario adapted the United States Department of Agriculture’s Universal Soil Loss Equation (USLE) as the tool for estimating rates of soil loss by water erosion from cropland and identifying management practices that could reduce these loss rates to tolerable levels. Since then, the USDA has significantly revised the original USLE, to the point where most conservation planning in the USA is performed using the Revised Universal Soil Loss Equation 2 (RUSLE2) model. Significant effort is needed to build the databases necessary to adapt RUSLE2 for use in southern Ontario. This paper/poster describes the process and work to-date on this effort. The end product is anticipated to be applied both as a stand-alone tool as well as incorporated into Ontario’s NMAN software. It is expected to be used to assist in identifying suitable erosion control practices for today as well as under climate change conditions predicted for Ontario.
