northwest Indiana | I made the same switch. I have found that I am using a little less seed in most cases because I optimize the top rate for the best ground and scale it down over the various soil types instead of planting for the good ground and over planting the poor soils. I save around 1500 seeds per acre in most cases. I also don't have the overpopulation problems on the poor soils. The part of the switch that make it pay is the row clutches. That is a no-brainer to me. I save about 12 bags of seed on 700 acres of corn. That pays back pretty quickly. I determined the saving when I didn't use variable rate the first year and set the planter exactly at the ground drive rate from the prior year and used 12 less bags of corn. | |
