Hoover Ag’s manure dragline injectors place liquid manure directly below the soil surface instead of leaving it exposed on top. That single difference cuts nitrogen loss, reduces odor, and improves nutrient uptake compared to surface application methods like broadcast spreading or dribble bars.
Our injectors are built for dragline systems and available as row-unit configurations with 15, 24, or 30-inch spacing, so you can match the setup to your crop and soil conditions. A patented adjustable opener angle lets the same machine handle everything from grassland to medium-disturbance injection, and folding row units keep transport width manageable between fields.
These are engineered from real farm experience — Eric Hoover built his family farm’s first dragline injection system before developing the adjustable-angle design now used across the line. The result is equipment that reduces field passes, minimizes compaction, and gets nutrients where they actually do the most good: in the root zone, not sitting on the surface.
