LiquiJect’s SpikeWheel technology provides subsurface injection of liquid fertilizers, soil surfactants, insecticides, fungicides, herbicides and other liquid solutions 2 ins. below surface of greens, fairways and athletic fields while it simultaneously aerates turf. Usable on slopes up to 25%. Delivers liquids directly to turf roots, eliminating evaporation or runoff and decreasing human and animal exposure. Areas are usable immediately after treatment because no soil cores are extracted. Models offer tank sizes from 30 to 150 gals. LiquiJect LLC, Helix, Ore.
