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

Authors: Mahdi Al-Kaisi (Iowa State University) , Alex Cleveringa (Iowa State University)

Abstract

Tillage systems and crop rotation significantly affect soil carbon and soil productivity in the long-term, including the physical, biological, and chemical soil quality indicators. Additionally, tillage systems and crop rotations control weed and soilborne 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.
