‘How much do I put where?’ Especially for seed and N rates. this is the question precision ag has been pondering for over two decades. Veris began answering the ‘where’ part in 1996 and continues to develop even more precise soil sensing solutions. The ‘how much N’ question is beginning to be addressed—see the FieldView article in this issue.
Now an exciting multi-state project is tackling the ‘what population and what N rate are optimal’ for local and regional soils across the corn belt and beyond. Researchers and farmers are collaborating on the Data Intensive Farm Management (DIFM) project and conducting large scale, on‐farm “checkerboard” field trials. Led by David Bullock, Professor of Ag Economics at the University of Illinois, the goal of DIFM is to revolutionize farm management by working with farmers to implement scientific experiments on their own farms.
What makes this unique are two important aspects: One, it’s very simple for the grower to execute. The prescription rates are delivered with standard variable rate drives, and harvested with a normal combine with yield monitor. Two, the fields will have Veris EC-OM-pH data collected, so the results will be analyzed by the research team focusing on responses by soil properties. It’s likely that soils with higher water-holding capacity should have populations bumped up—but how much? That’s the kind of question this project will answer—locally and regionally.

Then and now: Soil characterization on the Morrow plots at the U. of IL—the oldest continuous research plots in the United States. The university will be mapping DIFM project fields with their new Veris U3.
