Seed pods of a winter canola plant are silhouetted against the setting sun in Bob Schrock’s field near Kiowa, Kan., on June 6, 2006. The canola industry wants to expand its winter crop to meet a strong demand and make better use of land that often sits dormant during the winter. They say there is demand for additional production and that planting canola can help improve nutrient levels in soil, reduce weeds and pests and help reduce erosion.
