Abstract

Everyone agrees that soil erosion is detrimental to Iowa agriculture. This study attempts to quantify the effects of erosion on contemporary crop yields and gauge the longer term impact on the agricultural economy in the state.

Key Question

What is the impact of existing soil erosion rates on crop yield and subsequent income alterations?

Findings

Field measurements of topsoil depth coupled with crop yield monitor data were combined to identify the relationship between topsoil depth and corn yield. From this data, and other research complementing this study, short- and long-term economic impacts were estimated.
