What Turf Professionals Are Saying
Increased thatch breakdown and soil profiles led to much healthier turf, which required less water, fertilizer, and chemical inputs!
Our greens are noticeably healthier, firmer, and more resilient to disease, drought, and stress.
DPH program gives the Turf Manager a great non-invasive tool to reduce compaction.
