Abstract:
1. A method of injecting viscous fertilizer below the surface of the soil, comprising: creating a pressurized stream of viscous fertilizer; and injecting at least some of the pressurized stream under the surface of the soil along a path, wherein the pressurized stream of viscous fertilizer is created using an apparatus comprising: (a) an upwardly open container box with at least a first, second, and third side wall, said third side wall having an outlet hole through which said viscous fertilizer may pass outside said container box wherein said third side wall additionally comprises one or more surfaces obliquely facing said push blade so as in operation to direct said viscous fertilizer toward said outlet hole; (b) a push blade disposed so as to prevent said viscous fertilizer from escaping said apparatus from the side of said container box opposite said third side wall; (c) a means for moving said push blade at least partially within said container box toward said third side wall to effect exit of contained viscous fertilizer through said outlet hole; and (d) a pump whose inlet is in communication with said outlet hole.
