A Chance to Remediate Tillage Erosion

David Lobb, professor in the department of soil science at the University of Manitoba, and senior research chair for the Watershed Systems Research Program, has been studying the effects of tillage erosion for over twenty years.

Tillage erosion is the process whereby soil is moved down slope, to convergent areas of a field. It causes severe losses of valuable organic matter to hilltops and hillsides. According to Peter Johnson, RealAgriculture’s resident agronomist and host of Wheat Pete’s Word, tillage erosion can be up to ten times worse than wind and water erosion — combined.

In this podcast, recorded at the Canadian Forage and Grassland Conference in Saskatoon, SK, RealAgriculture’s Debra Murphy talks to Lobb about agriculture’s role in water erosion, the differences in eutrophication and sedimentation, and how tillage erosion is putting some areas on the map (and not in a good way). Lobb also explains how farmers can reverse the impact of tillage erosion, and how studies have shown moving soil back up slopes is environmentally and economically feasible.

David Lobb talks to Debra Murphy at the Canadian Forage and Grasslands Association Conference in Saskatoon. The duo discuss erosion, focusing the latter part of the discussion to tillage erosion, and how it can be reversed. C
