Subsurface placement of fertilizer under no‐till, small‐grain soil fertility research presents unique problems to researchers if minimum soil disturbance and minimum residue incorporation is desired. A fertilizer applicator/planter was built from commercially available parts and designed to allow evaluation of fertilizer rates, sources, and placements under no‐till, small‐grain production. It has been demonstrated to successfully plant through at least 3000 kg/ha of year‐old prostrate residue and through 4000 kg/ha of fresh, standing small‐grain residue. Residue levels higher than this have not been tested. Three people can fertilize/plant 50 plots/h, changing rates, placements, and sources.
