TRAFIC - COMPACTION - WEAR

Criteria for maximizing surface stability and traction on Seaisle 1 sports fields

Carefully select sand particle size, uniformity, gradation, and shape

Incorporate 1-3% (by weight) organic matter prior to grass establishment to enhance stability

Use a rootzone mix with rapid drainage characteristics

Install good surface and subsurface drainage

Maximize root growth of the grass through good management   - Proper fertilisation (spoon-feeding, particularly N-P-K )   - Proper mowing height to maximize carbohydrate production   - Proper irrigation scheduling (infrequent, but deep percolation)   - Timely applications of plant growth regulators   - Maintain high shoot density and turf shoot/root biomass to resist     wear injury

Provide a protective cushion against compactive forces   - Regularly scheduled aeration   - Light sand topdressing   - Use of crumb rubber   - Avoid extremes in dryness or wetness by carefully scheduling     irrigation - generally 1 inch (25 mm) per week depending on     climate   - Develop a topdressing program that controls thatch, creates a     mat-thatch layer intermingled with sand or soil, maintains a level     playing surface, and amends the surface soil texture when needed   - Limit thatch to <13 mm (<0.50 - inch)   - Use soil stabilisation materials when needed   - Avoid excess N fertilisation (which increases leaf growth and     enhances color at the expense of root/stolon/rhizome development   - Aerate, aerate, aerate on a regular schedule
