Western Producer: When topsoil moves uphill

Schoenau and his fellow scientists conducted the experiments near Central Butte, Sask. The topsoil replacement produced the “highest spring wheat yield … (due) to better soil fertility and water-holding capacity associated with thicker topsoil,” says a poster summarizing the research.

The findings have been around for a few years and match the results of similar experiments by University of Manitoba researchers.

David Lobb, a U of M soil scientist, has conducted field trials on moving topsoil to the tops of knolls at multiple sites in the northern Plains. The results were dramatic.
