We purchased a new to us FC 5000 TBH 3450 with NH3 tank behind. Our canola emergence in the tire tracks is not great. I have a few neighbours with the same setup but they don't seem to have any issues with emergence that I can see from the road. I'm assuming its a compaction issue. Has anyone else had to address this and what was the solution? The NH3 tank is a 2000 gal single tank with spaced floatation tires. Only one set of tires overlaps the air cart tires. Or could it be nothing to do with compaction but a problem with seed placement and packing?
