Crops & Soils
The Rock County Crops and Soils program provides educational programming, which promotes agricultural productivity and profitability while protecting the environment. Producers and Ag-professionals benefit from access to the latest, unbiased research based information while the general public enjoys an environment protected by efficient nutrient and pesticide use. We emphasize local research, both in farmer fields and at the Rock County Farm to address emerging issues. Major programs include:
the Rock County Farm located on US Highway 14 just west of Janesville, WI.
Giant Ragweed Research Summary: What we have learned from 6 years of chemical giant ragweed control in corn and soybean.
The Wisconsin Herbicide Evaluation Program has conducted several chemical manufacturers and commodity board sponsored corn and soybean trials assessing giant ragweed control every year since 2018. The results of this work have been summarized and presented in the Wisconsin Weed Science Research Report.
