초록 ▼

This invention relates to an improved apparatus for applying a combination of liquid and gaseous fertilizers while at the same time tilling the ground which comprises providing the trailing edge of a conventional V-blade plow with an orificed pipe through which liquid anhydrous ammonia is pumped under pressure and a plurality of open-ended drop feeder pipes having their open ends terminating alongside one of the ammonia outlets through which the liquid phosphate issues in close proximity, say three inches or closer, to where the ammonia is dispensed. The invention also encompasses the unique method of introducing nitrogen and phosphorous into the soil so as to take advantage of the known phenomenon wherein the ammonium ion (NH4+) stimulates the utilization of the phosphorous which includes the steps of tilling the ground to a shallow depth using a V-blade plow, injecting anhydrous ammonia under pressure into the freshly tilled ground immediately after the plow has passed therethrough and freely dropping liquid fertilizer containing soluble phosphates no farther than approximately three inches from where the anhydrous ammonia has been deposited.

대표청구항 ▼

For use in combination with a V-blade plow having downwardly and forwardly-inclined angularly-disposed blades with leading edges for plowing and trailing edges elevated therebehind, the improved distribution system for placing two different types of liquid fertilizer into the freshly plowed ground and mixing same “in situ”which comprises: a first tubular member having an inlet connectable to a pressurized source of nitrogen-bearing fertilizer in liquid form, a horizontally-disposed portion fastened to the trailing edge of each plow blade in shielded relation therebehind, means defining a closure for the end of said horizontal portion remote from the inlet, and at least two downwardly-directed discharge orifices for dispensing said nitrogen-bearing liquid fertilizer received from the pressurized source thereof directly into the plowed ground in transversely-spaced rows; and, other tubular members corresponding to each of the discharge orifices in the first pipes connected alongside thereof in trailing relation thereto, said other tubular members each having an inlet connectable to an unpressurized source of phosphorous-bearing fertilizer in liquid form and a single outlet for dropping same onto the ground immediately behind and to the nitrogen-bearing fertilizer issuing from one of the orifices in the first tubular member.
