There is a need for education on soil conversation and conservation tillage in northwest Iowa. Additional corn on corn acres has increased tillage in northwest Iowa. However, fuel costs and the need for crop residue on highly erodible acres have created a demand for information on growing corn on corn with a no-till system.
The Iowa Learning Farm (ILF) staff and I set up two field days in my area for 2007. No-till corn on corn production was emphasized at both field days. The field days were June 29 at Fenton and August 27 at Webb (attendance 35, 60 respectively). The ILF rainfall simulator was demonstrated at both locations. No-till corn on corn production was discussed at each location by the ILF cooperator.
Survey information from the ILF survey (11, 17 surveys returned, respectively) of field day participants showed that 59% would consider the use of high surface residue management (no-till/strip till), and 48% would network their conservation ideas with their neighbors. Thirteen percent were already doing no-till and 10% would further discuss using no-till/strip till with landowners. One attendee commented that, there are more people interested in this than I thought kind of a positive reinforcement for our (no-till corn) operation.
