The Dual Placement System from Precision Fabrication LLC places the liquid nutrients 3 inches from the seed trench, on both sides, and the same depth as the seed. Placing nutrients in the root zone has proven to give the best crop yields for the fertilizer dollar. It is designed as a low pressure system to avoid getting splatter on the machine. Ten-inch openers run slightly “toed in,” thus creating 2 narrow trenches into which the fertilizer is streamed at very low pressure. Eleven models cover many popular planter row units.
