Abstract: Liquid nutrients are applied to a first group of rows of standing crops by pulling a drag hose from a reel located at one end of a field and between two crop rows with the drag hose connected to an applicator pulled by a tractor or track units. The hose provides a liquid supply to the applicator. At the opposite end of the field, the applicator is turned 180°, and in one embodiment, a boom pivots to project from one end of the applicator to the drag hose. The applicator returns down adjacent crop rows back to the first end of the field with the applicator connected to the drag hose while the reel simultaneously retracts the drag hose between the two crop rows. The reel is moved axially to a third group of crop rows along with the applicator, and the steps are repeated.

Abstract: Liquid nutrients are continuously applied to a first group of rows of standing crops by pulling a drag hose from a reel located at one end of a field and between two crop rows with a boom having one end pivotally connected to an applicator and a tractor. The boom provides a liquid supply line from the drag hose to the center or one end of the applicator. At the opposite end of the field, the tractor and applicator turn 180° while the boom pivots to project from one end of the applicator to the drag hose. The tractor returns down adjacent rows back to the first end of the field with the boom projecting to the drag hose while the reel simultaneously retracts the hose between the two crop rows. The reel is moved axially to a third group of rows, and the steps are repeated.
