TURF TOPDRESSING · ENGINEERED FOR SOIL HEALTH
THE SCIENCE
OF RESTORING
STRESSED TURF.
A 1/2-inch layer of Class 1 compost with injected turf seed — placed pneumatically — rebuilds organic matter, feeds the soil biology, and increases organic content of soil by 3 to 4 times.

WHAT MAKES IT
CLASS 1 COMPOST.
Mature, stable, screened, and lab-verified. The same grade specified by CDOT, USCC STA, and most municipal park standards — not bagged topsoil and not raw manure.

SOIL ORGANIC CONTENT
A single pass can triple to quadruple the organic content of typical Front Range turf soil.
// MICROBIOME
10⁹
CFU PER GRAM
Mature Class 1 compost delivers ~10⁹ microbes/gram — restarting the soil food web at the root.
// GERMINATION
2×
SEED-TO-SOIL CONTACT
Injecting seed into compost yields roughly 2× the establishment of broadcast-only overseeding.

ONE PASS. REAL RESULTS.
COLUMBINE ELEMENTARY · 3-WEEK PROGRESS
HOW A JOB RUNS
Stage — truck parks up to 300 ft from the work area.
Inject — seed metered into the compost at the nozzle.
Apply — 1/2" even layer placed pneumatically.
Walk — final coverage check + photos for sign-off.
