Long-term Tillage and Crop Rotation Effects on Soil Carbon and Soil Productivity

Authors: Mahdi Al-Kaisi (Iowa State University) , David Kwaw-Mensah (Iowa State University)

Abstract

Tillage systems and crop rotation significantly affect soil productivity and quality in the longterm by affecting soil carbon and the soil physical, biological, and chemical properties. Additionally, tillage systems and crop rotations control weed and soil-borne diseases. There is a need for a well-defined, long-term tillage and crop rotation study across the different soil types and climate conditions in the state. The objective of this study was to evaluate the long-term effects of different tillage systems and crop rotations on soil quality and productivity.
