Hans Kandel

Agriculture is a major component of North Dakota's economy and my work at NDSU focuses on management practices for the production of broadleaf crops including soybean, sunflower, canola, dry bean, field pea, flax and other broadleaf crops except potatoes or sugarbeet. Soybean is the most important broadleaf crop produced in ND in terms of area cropped and value. In my position in the department of Plant Sciences, I take data, from agricultural research conducted at NDSU and similar regional universities, and use the information to present findings to agricultural producers in North Dakota (ND), Minnesota (MN), South Dakota (SD), and Canada, and to others in the agricultural industry. I have conducted production research on the various broadleaf crops and I have a major water management (tile) drainage research program.
