No-till research involving row space and subsurface fertilizer placement variables requires a planter that allows quick adjustment to provide a wide range of row space and fertilizer placement positions. A no-till planter with adjustable row spacing was constructed to allow fertilizer placement below seed, with seed, and any distance between seed rows. Row space was quickly changed to any width, including paired-row configurations, from 0.15 to 1.27 m. With two people it required 10 min to change row space, fertilizer placement, and rate. The planter was used to establish small grains, large- and small-seeded legumes, and wheatgrass. Planting was successful through 2200 and 3018 kg ha−1 of prostrate and standing small-grain residue, respectively. Higher residue levels were not tested. The planter was mounted on a 50-hp tractor with a three-point hitch.
