Organic farmers are in a tough spot when it comes to controlling weeds. Since conventional herbicides aren’t an option, many choose to use tillage — mechanically turning over the soil to upend weeds. However, tillage can take a toll on soil health and cause run-off. Increasingly, organic farmers are seeking better ways to control weeds while preserving soil health.
Our incoming freshman spent the weekend before classes start on a tour of agriculture industry and farms in northeast Iowa. They toured Beck's Hybrids in Marshalltown, Pioneer Hi-Bred in Reinbeck and Landus Co-op in Dike. A stop at UNI allowed them to cool down (the air conditioning broke on the bus) and learn about urban soil conservation on the UNI campus. Near Nashua they learned about soil health from the Iowa Natural Resources Conservation Service.
