摘要

Herbicide-resistant mares-tail and waterhemp have caused Illinois grower Trent Funk to work the ground during his three-year rotation of soybeans, corn and wheat. Historically, weed control was a key reason for tillage, but that justification hasn't existed for quite a while due to herbicide effectiveness, says University of Illinois professor of crop sciences Emerson Nafziger. However, it's coming back, at least in some areas. Funk explains his tillage rationale: "Soil conservation is definitely a good practice, and we no-till most of our soybeans, but you have to play the hand you're dealt. And right now the best option for weed control and improved yields on our land is tillage," he says. "I believe I'm giving up yield potential if I no-till corn, but I haven't seen yield drag on our no-till beans."
