Covered up: A look at no-till options
The front unit of the Sub-Surface Tiller-Transplanter, developed by Dr. Ron Morse for planting vegetable starts and potato seed through mechanically-killed or winter-killed cover crop mulches. The front disk slices the residue, the shank (whose depth is adjustable) loosens the soil without inverting or incorporating the residues, the tube delivers organic fertilizer, and the fluted coulter mixes it into the planting slot. A no-till transplanter with specially-designed press wheels then places seedlings or seed potatoes into the slot.
