A novel method for growing tall fescue sods on a solid base and harvestable 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 materials 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 approximately 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. |
