The overall goal of this research project is to develop management recommendations when producing soybean under no-tillage conditions under various soil types in Iowa.

There is evidence from previous research to suggest that soybean yield is influenced very little by tillage. In Iowa, a majority of acres are tilled and farmers in some parts of the state have avoided no-tillage soybean production because of the difficulty in maintaining competitive yields to tillage systems. A limitation that exists for farmers wishing to adopt no-tillage systems is the lack of recommendations specific to no-tillage systems.
