1. Basic Considerations of Soil Compaction, Tillage, and Crop Problems Soil compaction is one of the mosc challenging variables in crop production in the Midwest. It affects early crop growth and can lead to yield reductions. The most unusual aspect of soil compaction is the variety of crop symptoms that can develop. Few absolute answers are available on the topic of soil coapac- tion. Our research is lixited to the effects of different soil conditions on yields and some early synptoms that can be caused by soil compact ion. We have developed three principles that... G.C.

2. The New Wisconsin Soil Test Recommendation Program The modern Wisconsin soil testing program was originally developed in the early 1960's. It was revised rather thoroughly in 1970 and again in 1981. New research advances, additional correla- tion and calibration data, changes in user needs, and shifts in philosophical viewpoint make it necessary to periodically review the soil testing program and the recommendations that emanate from that program. The current revision is an attempt to incorporate additional research, eliminate certain inconsistencies... Download paper
3. Tillage and Nitrogen Application Methodology Affects Corn Grain Yield More efficient use of fertilizer nitrogen (N) is essential for improved yields and environmental stewardship. While university N recommendations for corn are based on observations typically made in conventional tillage systems, few universities have established research to evaluate if N recommendations should be different for alternative tillage systems. Generally spealung, no-till or minimum tillage systems have been identified as needing additional N to compensate for microbial immobilization of... Download paper
4. A Combination of Soil Incubation and Chemical Extraction Tests Best Predicts Corn Yield Response to Fertilizer Nitrogen Soil tests in general have served a critical role in the field of soil fertility for over half a century, and have helped to increase crop productivity and promote more efficient use of fertilizers on farms. However, N soil tests have limitations and chemical extraction tests have not predicted well the potentially mineralizable N supplied to corn over a growing season. Thus, these tests often do not accurately predict a corn’s yield response to fertilizer N. We explored 30 soil tests for... M. Mcdaniel, D. Walters, L. Bundy, C. Laboski, P. Scharf, R. Drijber, W.
