Irrigation is the process of applying controlled amounts of water to plants at needed intervals. Irrigation helps grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas. It also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil consolidation.
Sod is grass and the part of the soil beneath it held together by its roots or another piece of thin material. When properly installed and cared for, sod provides a lawn you can enjoy immediately.
