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 (NH. sub. 4 +) 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.
