Nick Moon, PhD chemist with Milliken discusses the benefits of utilizing the patented, regenerational, multi-branch hydrating surfactant technology.
Moisture Management Solution
Soil Hydrating Surfactant with Organic Acid Redistribution System
OARS HS, Soil Hydrating Surfactant, is a combination of the university researched, field proven, and patented organic acid redistribution system (OARS) with a multi-branched hydrating chemistry. OARS HS controls soil water repellency while providing uniform soil moisture and increased soil moisture retention.
• Removes humic coatings from hydrophobic soil particles
• Controls water repellency
• Increases number of hydrating sites to improve moisture retention
• Provides superior soil moisture uniformity
• Increased length of activity in soil
• Reduces drought stress
• Consistent performance between applications to maintain adequate moisture in hard to wet soils
• Money back guarantee
Golf, Lawns, and Sports Turf
Apply 4 to 5 ounces per 1,000 ft² in 2 gallons of water (13 to 16 L/ha in 800 L) at 30 day intervals or as needed. After an initial 5 ounce (16 L) application, drought conditions can be best managed by applying 2 to 2.5 ounces per 1,000 ft² in 2 gallons of water (6 to 8 L/ha in 800 L) at 15 day intervals or as needed..
For extreme drought conditions with high temperatures and/or increased soil water repellency, apply 6 to 8 ounces per 1,000 ft² in 2 gallons of water (20 to 25 L/ha in 800 L) at 30 day intervals or as needed.
Irrigate with sufficient water to deliver OARS HS to the soil profile – 1/8 inch (3 mm) or more recommended.
OARS HS Research
Evaluation of two commercially available wetting agents on soil moisture management
Evaluation Time Frame: March 18, 2017 to July 14, 2017, 119 Days
Location: Penn State University, Joseph E. Valentine Turfgrass Research Center
Trials were conducted on pots containing a fairway material consisting of 70% sand and 30% soil. Two applications were made at label recommendations. Two applications of OARS HS – Regenerating Multi-Branch Surfactant were made at 5 oz per 1000 square feet. Two applications of an industry leading modified/methyl – caped block copolymer surfactant were made to the same fairway material at 6 oz per 1000 square feet.
Evaluation of OARS HS regenerating branched surfactant and industry leading modified/ methyl-caped block copolymer turf surfactant on soil moisture management of an L-93 creeping bentgrass fairway grown on a 70/30 construction mix. 22% volumetric water content (VWC) was the target moisture rate. Rewetting of the matrix occurred once 15% VWC was measured. Both measurements were completed using a Spectrum TDR 300 moisture meter. The dry down was initiated on May 19, 2017.
OARS HS pots required 48% less water than the control pots maintained at 22% VWC. 48% less water is equivalent to 1,925,000 gallons of savings for 25 acres of fairways in an 8 week period. OARS HS outperformed the industry leading surfactant for saving water by 23.4% and required less watering cycles than the control.
