Subsoilers from Kellough's

Soils can become deeply compacted for a number of reasons. Layers of compacted soil restrict the movement of water, air, and roots, reducing the survival and growth of plants and trees. These compacted layers typically develop 12 to 22 inches below the surface where conventional cultivators can’t reach.


These layers require special equipment known as  Subsoilers or Rippers, to fracture them, break up compacted layers and return the soil’s structure to a more natural state.


Subsoiling fractures compacted soil without adversely disturbing plant life, topsoil, and surface residue. Fracturing compacted soil promotes root penetration by reducing soil density and strength, improving moisture

infiltration and retention, and increasing air spaces in the soil. How effectively compacted layers are fractured depends on the soil’s moisture, structure, texture, type, composition,

porosity, density, and, clay.
