It seems like this rather indicates that the USDA erosion tolerance is too high to meaningfully slow the rate of erosion. 1mm is not a useful target given that the average pre-agricultural rate of erosion is 0.04mm--this paper says that the pre-agricultural erosion rate was much lower than expected and this means modern practices are still causing more damage than previously understood and tolerance should be lowered by an order of magnitude. |
