Bismarck Tribune 36

A.D. McKinnon, state coordinator for the federal Soil Conservation Service, encourages farmers in North Dakota to “inspect…fields and plan corrective measures where valuable water is going to waste”. McKinnon suggested that farmers “plow and crop on the contour…to hold water evenly on the field where it will stay in the soil for crop production and soil protection”.
