Sea Isle 1
This new fine-bladed seashore paspalum cultivar, developed by Dr. R.R. Duncan at the University of Georgia's Griffin Experiment Station, is ideal for golf course fairways, tees, and roughs. It makes a fine choice for sports turf, home lawns and commercial landscaping, too. It's a grass that thrives on salt water. You can irrigate Sea Isle 1 using a seawater blend, or even straight ocean water with the right management practices. It also grows quite well when watered from recycled or effluent sources.
Can be used on fairways and tees. Sea Isle 1 adapts well to most all soils and does exceptionally well in areas where it is difficult to grow bermudagrass.
Sea Isle 1 has a very fine leaf blade with excellent green color that can be closely mowed to heights of 1/4 inch.
Water Quality Tolerance
The most outstanding feature of Sea Isle 1 is its exceptional salt tolerance. It will proliferate in soils irrigated with water containing 2,500 ppm dissolved salts, and will show only a 50% reduction in growth at 5,000 ppm. It is considerably more salt tolerant than bermudagrasses and zoysiagrass.
Sea Isle 1 spreads quickly during establishment and forms a dense turf which will compete with the presence of weeds when properly maintained. However, all paspalum selections are sensitive to many pre- and post-emergent selective herbicides. Use only pesticides labeled for paspalum.
Soil Fertility Range
Sea Isle 1 grows best in soils with a pH above 6.0. It performs best on a low level of applied Nitrogen, approximately 3 pounds N/1000 square feet per year. Given a balanced N:P:K program according to soil tests, Sea Isle 1 performs well in a fertility program of about 50 to 70% of the amount required for Hybrid Bermudagrasses.
All paspalum selections are sterile, and must be propagated by sod or sprigs.
Sea Isle 1 Research and Evaluation
Sea Isle 1 can only be sold as certified sod or sprigs, and only by licensed members of the SeaIsle Growers Association. This group of quality-conscious sod producers has agreed to the stringent production practices set up by the Georgia Seed Development Commission. You can be assured of Sea Isle 1's genetic purity. As a certified turfgrass, it's grown, inspected and sold under a rigourous set of guidelines designed to ensure ongoing purity and uniformity.
