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: Silencing and separation in a cold-air, essential-oil, diffuser apparatus and method pass flow through a channel having comparatively high aspect ratios of length to thickness and width to thickness. Curved, tapered, non-parallel, and quasi random surfaces reduce probability and power of resonant frequencies. Offsetting flow through a channel is followed by impingement against an obstructing surface, redirection elsewhere within a drift (separation) chamber, and exiting through a smaller, and differently oriented exit port. Silencing is improved by changes of cross-sectional area creating high-pass and low pass acoustic filters, changes of direction, and absorption of acoustic energy in fluid-droplet-laden air.
