We’ve Done Our Research
University research shows, and turfgrass managers confirm, DryJect is a proven industry standard method of turfgrass management and a beneficial part of any agronomic program. For over 25 years, DryJect’s test results have demonstrated the impact and efficacy of the DryJect system on soil health and turf resiliency.
Key Research Results
DryJect® Recovers Up to 3X Faster Than Hollow Tine Aerification
Agronomic and Economic Impact of DryJect vs. Other Aerification Methods: Novel Organic Matter Management Strategies, Mississippi State University
Research from
Ohio State University
Shows DryJect to be more efficient in cost and time lost than core aeration
Organic Matter Content in
Push-Up Green
Research shows no significant difference in organic matter control between DryJect and core aeration; therefore, therefore no justification for core aerification disruption to play and operations versus DryJect’s minimal downtime.
Infiltration at 3” Depth – Higher Infiltration with DryJect
The highest infiltration was obtained with DryJect aeration, and with DryJect in combination with core aeration. The effect lasted over 80 days. For the first 15 days, the infiltration rate was approximately double the control.
Compaction Push Up Green – Softer with DryJect
Below 2” in the soil profile, standalone DryJect treatment, and DryJect with core aeration, showed a softer, less compacted soil with the effect exceeding 60 days while maintaining a firm surface.
Organic Matter Content in
Sand Green
Efficacy of standalone DryJect treatment confirmed. There was no significant difference in organic matter control between DryJect and core aeration.
Infiltration at 3” Depth – DryJect Treatment Doubles Infiltration Rates!
The highest infiltration was obtained with DryJect aeration, and with DryJect in combination with core aeration. The effect lasted over 80 days. For the first 15 days, the infiltration rate was approximately double the control.
Root Zone Compaction Below 2” Reduced with DryJect
DryJect aeration, and DryJect with core aeration, showed a softer, less compacted soil with the effect exceeding 60 days while maintaining a firm surface.
Club Recovers 42% of Lost Revenue with DryJect®
It pays to DryJect! Golf club general manager does the math and shares the report with his peers. Results indicate that clubs that substitute just one in-house aerification with a DryJect service can save 42% in related revenue due to course closures and other factors. Report by Justin M. Smith, general manager at Olde Homestead Golf Club in New Tripoli, PA.
