Claim:
A procedure for planting seeds in the ground, comprising: creating a slit-opening in the ground, by drawing an angled knife blade having a knife-edge through the ground; simultaneously depositing the seed in the slit opening, right behind the angled knife blade; maintaining the angled knife blade at a depth of no more than about 15 cm vertically down into the ground; while the knife blade is being drawn through the ground, maintaining the knife-edge at an angle relative to the ground; wherein: in front view relative to the direction in which the knife blade is drawn, the knife-edge makes an angle relative to the ground, termed the side-slope-angle, of between 30 and 60 deg to the horizontal, and in lateral elevation, the knife-edge makes an angle to the horizontal, termed the forward-pitch-angle, of between 30 and 60 degrees, and the knife-edge slopes forwards in that view, in that deeper portions of the knife-edge in the ground lie ahead of more shallow portions of the knife-edge.
