Revisions to the universal soil loss equation implemented in the mid 1990s to more accurately predict soil erosion caused by water. It includes the same factors as the earlier formula; climate, soils, topographic conditions, and the degree to which the use and management of the soil reduces erosion. But it takes advantage of new knowledge about these relationships and the capabilities of computer technology. The comparison between predicted erosion and T-value is important in making and carrying out conservation plans and achieving conservation compliance.
