Case Studies and Data
HILLCREST COUNTRY CLUB
Hillcrest is 29-time host to the Korn Ferry/Web.com tour, the Boise Open. Before beginning a PRM program, Hillcrest had moderate thatch layering, low infiltration rates, with prevalent dry and wet spots in different areas on the course.
YEAR 1 PRM RESULTS:
- Thatch reduction — 61% decrease
- Drainage improvement — 77% increase
- Root zone expansion — 70% increase
Over the course of the year, Hillcrest experienced a reduction in localized dry and wet spots, and reduced hand watering by over 90% in June. Assistant Superintendents also noticed the irrigation system ran more efficiently as they rarely had to service filters on sprinkler heads. Thatch reduction, drainage improvement, root zone expansion, and reduced compaction were observed year after year.
Eagle Hills ran a scaled trial of PRM during the 2019 season, running an isolated program on the front 9 in order to keep the back 9 as a control.
- Thatch — 36% decrease
- Root zone — 81% increase
- Compaction — 41% decrease
- Drainage — 15% increase
- Thatch — 7% increase
- Root zone reduction — no change / slight decrease
- Compaction — 20% increase
- Drainage — 55% decrease
5 tee before, with inconsistent turf density, color and signs of heat stress.
5 tee after, visibly more dense, consistent, and no signs of heat stress.
7 apprach before, with similar issues to 5 tee displaying heat stress, poor density and dry spots.
7 approach after, showing an improvements in color, density and no heat stress.
Before PRM Riverbirch suffered from severe latch layering (1-2″) that created an entirely perched water table, with little to no roots reaching into the compacted, dry soil (VWC 4-6%).
- Reduced thatch and compaction
- Root zone expansion
- Increased turf density
See photos below for visuals of Before / After comparison of the PRM trial at Riverbirch.
Dry brown patches cover both the Test and Control areas.
Test area has improved in color and turf density.
Root Zone Before
Shallow root zone before, which stayed consistent in Control.
Root Zone After
Root depth increased by several inches in Test area.
Pinecrest ran a PRM trial on their greens during the 2019 season. Before beginning a PRM program, Pinecrest experienced moderate thatch layering, compaction and infiltration rates on their greens. We demonstrated a significant improvement in turf quality and playing conditions with PRM.
- Thatch — 60% decrease
- Root zone — 148% increase
- Compaction — 90% decrease
- Drainage — 17% increase
See photos below to see the overall difference in turf quality. We saw improvements in denser, greener and more consistent turf.
7 green before, with inconsistent density and color.
7 green after, looking denser and more consistent.

Before beginning a PRM program, Arizona National faced issues with compaction, high runoff, bare spots throughout fairways, and thin roughs with low turf density. Their location in the Sonoran Desert also meant extremely high expense for water and fertility.
2016-2017 PRM TRIAL RESULTS:
- Turf filled in and density increased
- Improved water infiltration and decreased runoff
- Saved $130,000 in water
- Saved $80,000 in fertility
- Set record for number of rounds played — over 4,000 in March 2017
Turf conditions before PRM treatment began: bare spots and poor playing conditions.
Improved playing conditions and consistent turf after treatment.
Before beginning a PRM program, Quail Hollow experienced inconsistent turf density, moderate-severe thatch layering, and very poor infiltration rates.
- Reduced compaction — 44% decrease
- Root zone expansion — 65% increase
- Drainage improvement — 170% increase
See photos below to see the overall difference in turf quality. We saw improvements in greener, more consistent turf across the course.
