Harrison History

The Harrison County landscape includes both hills and valleys. Farming techniques differ depending on the topography of the farm because what works in the valleys does not work in the hills and vice versa. Tillage is not used in the Loess Hills but it is in the bottoms.As seen in 2019, flooding on the Missouri River bottoms is a significant challenge that affects management. Deposition of sand affects how locals farm, and weed seeds are spread during flooding as well. The high water table affects other aspects of management.

Harrison Pests

The Harrison County Pest Resistance Project initially began in 2017 as a result of the introduction of Palmer amaranth in the county four years prior. As most farmers in the area are grappling with herbicide resistant weeds but do not have Palmer in their fields yet, the project was expanded to include waterhemp, marestail, giant ragweed and disease trials as well. Read below to learn more about local disease and weeds and why they were included in this project.
