Two events provide the catalyst for this column. First, was the passing of a dear friend Elmer Stobbe, a soil scientist whose career at the University of Manitoba extended after retirement to consultation in Abbotsford BC. The second was my annual interview with a radio station in Yorkton, Saskatchewan, to discuss current weather patterns and expectations for the 2019 growing season. Elmer specialized in soil erosion and especially preventative measures including zero-till and minimum till. In Canada, this work was triggered by the work of Canadian Senator Herbert Sparrow. A farmer from Indian Head, Saskatchewan, also the site of a major agriculture research centre in western Canada. He lived through the dust storms of the late 1930s and witnessed first-hand images similar to a 1933 dust storm in Regina (Figure 1).
