Abstract
Abstract A combined liquid fertilizer dispensing and soil compacting device for cultivators as for example, chisel plows, shovel plows, etc., wherein liquid nitrogenous fertilizer, i.e., anhydrous ammonia is supplied from a suitable source to and flowed through tubing secured and extending longitudinally of and along the trailing side of an earth-working chisel or shovel plow carrying shank to a depth below that of the soil surface level being cultivated where it is anchored thereto and discharged thereinto and diffused therethrough thus fertilizing the tilled soil which is thereupon firmly compacted and sealed by means of a shank pivotally connected and drawn member, thus preventing the loss of its efficacy by osmosis and evaporation.
