Ive farmed here in NE Okla for 25 yrs nearly, Never been satisfied with the yeilds herer, Ive farmed in NE Kans, and NW Mo. and here is the worst. Ive used granular fertilizer in my corn and milo, put on during planting, in the row, to varied resultrs across the field. I use Hybred corn, and Ivew used open pollinaterd, no difference, spotty yield regardfless. Next year, im going to have C S spread on the ground and see what it does. At the very least itall saver mt tons of time not having to stop and refill the fert pots. I was just wondering if anybody else had used it, and how they felt aboout it if they had. The diff in yielde, and price.
