Introduction

This publication provides information that can help farmers in the Lower Mississippi River Basin of southeastern Minnesota optimize performance of their tillage system for both erosion control and profitable crop production. It identifies key farm management practices needed to manage production risks associated with reduced tillage and no-till systems. It also draws on more than 18 years of University of Minnesota field trials to help evaluate how particular types of reduced tillage systems perform in different crop rotations in the two sub-regions of the basin: 1) the eastern "Karst" area where wind-deposited (loess) soil overlies fractured bedrock, and where internal soil drainage is generally excellent; and 2) the western "loess-cap" area where loess soil overlies glacial till deposits that often provide poor internal soil drainage.
