Techniques for Rapid Sod Production1
- R. E. Burns
The approximate time when sod is to be used is known several months in advance. Therefore, sod can be preordered and then produced for the specific need. Methods of producing sod in a relatively short time were studied near Atlanta, Ga., USA. ‘Tifway’ bermudagrass (Cynodon sp.) was sprigged in early summer in an 80-mm layer of solid sewage sludge from a secondary treatment plant. Tall fescue (Festuca arundinacea Schreb.) was seeded in the fall and winter in a Cecil sandy clay loam, in which 5-mm plastic mesh had been placed approximately 5 mm below the soil surface. Sod strength was measured by applying a slowly increasing force to a 0.3-m wide strip of sod.
The bermudagrass sod had a strength of 12 kg 2 months after sprigging which increased to 17 kg after 5 months. Sod grown on sludge obtained from an industrial area exhibited more environmental stress when transplanted than sod grown on sludge originating from a residential area. After 7 weeks the fall fescue with a single layer of net broke at 45 kg force, a double layer of net required 75 kg, and netting without sod broke at 34 kg. Sod with no net was too weak to remove from the ground. Three-month-old tall fescue sod produced twice as many roots with double the length of those produced on 7-month-old sod. The tall fescue showed no signs of environmental stress when transplanted during winter or early spring months.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
