A sub-surface seeding, fertilizing and watering device includes an opening blade (14). The opening blade (14) has first and second sides extending between a leading edge (68) and an aft edge (16) on the blade (14). The first and second sides are generally symmetrical to each other. The opening blade (14) is mountable to a material feeder so as to be generally vertically disposed when mounted thereon for partial submerging into soil to a first submerged depth during forward translation advancing the leading edge (68) through the soil. First (20) and second (22) wings are mounted to the first (26) and second (28) sides respectively in generally oppositely disposed relation so as to be cantilevered outwardly therefrom. The first (20) and second (22) wings extend between first and second forward wing edges and first (62) and second (64) aft-opening wing apertures in the first (20) and second (22) wings resepctively. The opening blade (14) has first (36) and second (38) conduits therethrough, extending from, and cooperating with, at uppermost ends thereof, first (30) and second (32) infeed ports in the upper surface. The first (36) and second (38) conduits cooperate with, at lowermost ends thereof, first (58) and second (60) wing ducts extending aft through the first (20) and second (22) wings respectively between the lowermost ends of the first (36) and second (38) conduits and the first (62) and second (64) aft-opening wing apertures. The first (36) and second (38) conduits and the corresponding first (58) and second (60) wing ducts are thereby in material flow communication between the first (30) and second (32) infeed ports and the corresponding first (62) and second (64) aft-opening wing apertures for seed, fertilizer or fluid flow, as fed from the material feeder, therethrough during the forward translation. |
