This paper discusses the recent increases in the returns to crop production as well as trends in land rental rates and the types of rental agreements used in the Midwest. The concept of a flex cash lease and an approach to defining the terms of such a lease, relative to the current fixed cash or share arrangement, are outlined within the context of an example Midwestern corn farm. The resulting flex lease results in returns to the tenant and landowner which are a hybrid of those realized under the more traditional fixed cash and share rent agreements. Using these alternatives as benchmarks, the approach to defining a flex lease could be applied to other specific farm scenarios.
