New Data from PCM with Focus on Cover Crops and Tillage. Precision Conservation Management (PCM) works directly with farmers and uses data analysis to determine how farmers can implement conservation practices without sacrificing profits. This webinar from Greg Goodwin (IL Corn Growers Association) and Gary Schnitkey (University of Illinois farmdoc team) covers 9 years of data-driven insights. We will emphasize profitable practices using cover crops. Profitability and tillage practices will be examined.
