Geoffrey N. Delin J.A. Lamb Lei Guo Matthew K. Landon 1993 <p>The northern cornbelt sand-plains Management Systems Evaluation Area (MSEA) program is a multiagency, multistate initiative to evaluate the effects of modified and prevailing farming systems on water quality in a sand-plain area in Minnesota and at satellite areas in North and South Dakota, and Wisconsin. The primary objective of Minnesota MSEA is to evaluate the effects of ridge-tillage practices in a corn and soybean farming system on ground-water quality. The Minnesota MSEA program is a cooperative study primarily between the U.S. Department of Agriculture Agricultural Research Service, the University of Minnesota Soil Science Department, and the U.S. Geological Survey. The Minnesota Pollution Control Agency and the Department of Geology and Geophysics at the University of Minnesota are also cooperating in the evaluation of groundwater quality at the MSEA.</p> application/pdf 10.3133/ofr9380 en U.S. Geological Survey Ground-water quality at the Management Systems Evaluation Area near Princeton, Minnesota, 1991-92 reports
