Abstract

A novel method is described for growing tall fescue sods on a solid base in large rolls. Whole culm straw is placed 1-2 inches deep over the solid base, typically plastic sheeting. Thirty to forty cubic yards of composted sewage sludge are then applied to the straw, filling the voids and interstices to produce a coherent matrix. This is seeded with tall fescue, then irrigated, fertilized, and mowed in a conventional manner. Unharvested wheat seed left in the straw germinates along with the tall fescue and forms a vigorous primary rooting system which rapidly effects a bona fide sod about one-half inch thick and aproximately one-half the weight of a conventional mineral sod. The synthetic sod is harvested in large rolls typically as much as five feet wide and comprising 20-50 square yards. These big rolls are laid at the installation site by the grading tractor, obviating the need for a fork lift, pallets, and laying crew as used in conventional sodding.
