Case Studies and Data
HILLCREST COUNTRY CLUB
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.
- 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.
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.
Quail Hollow’s hole 13 before, with inconsistent turf density and color.
Quail Hollow’s hole 13 after, looking denser and much more consistent.
Quail Hollow hole 3 before, with similar issues to 13 displaying thin/dry spots.
Quail Hollow hole 3 after, showing an improvements in color and density.
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.
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.
Performance Resource Management is a premium agronomic service designed to deliver superior results. By taking a holistic approach to resource management and improving the biological health of soil, we improve playing conditions, all while conserving water and reducing other operational costs.
