From Golf Industria.es, written by Zachary LaPorte (originally in Spanish).
After actually seeing the process and what was happening I began to understand why this machine was gaining popularity in the golf business. The air injected into the soil and into the root zone was not the only benefit this machine brought. He could imagine what was happening beneath the surface, the high pressure air injected breaking and loosening the soil, eliminating compaction to allow the roots to have more freedom and move through the ground. For me this was the most important detail and the benefit of air to the plant was a secondary advantage.
