Corn Row syndrome like that evident in the photo to the left ( taken June 15 ) is likely caused by more phosphorus being available to the wheat crop in the early spring green-up period.The tillage action of the fertilizer - double disk openers may be creating a conduit for moisture migration down through the soil profile after snowmelt thereby causing this area to warm up faster and allow more soil microbial activity to release phosphorus to the new growing wheat shoots.The photo above was taken of the same

section of field on June 21.You'll note how the crop has surprisingly evened out.Will there be a yield difference? Likely, but probably not near as much as you would have first thought.
