Tri-State Ag Day highlights residue effects on corn yields
University researchers at Lancaster discuss how corn row residue lowers emergence and yields in cold years, favoring trash whip use with minimum tillage. Surface residue helps water storage but slows nitrogen release. soil tests and pH, phosphorus, and potassium corrections are advised before adopting conservation tillage.

Subsurface compaction reduces corn yield and tips on nitrogen use
A UW Madison study led by Bill Lowery shows high axle load compaction from tractors and combines lowers corn yields and slows emergence, with reductions most evident in 1983 and diminishing in 1984. Recommendations include higher flotation tires, fixed tire tracks to reduce traffic, and tailoring nitrogen fertilizer based on soil residual nitrate to improve carryover and future soil recommendations.

Alfalfa Proves Key To Profitable Rotation In Wisconsin
An eight year study at Lancaster Experiment Station shows alfalfa as a high profit cash crop for southern Wisconsin farms. UW agronomist Roger Higgs notes continuous alfalfa hay can yield the most dollars, with $125 per ton hay and low input costs. Researchers compared rotations from continuous corn to corn with hay and soybeans, finding continuous hay most profitable, aided by alfalfa’s nitrogen contribution and soil benefits.
