| Irrigation |
The application of controlled amounts of water to plants at needed intervals, especially for the purposes of growing agricultural crops, maintaining landscapes, or revegetating disturbed or drought-affected soils. Irrigation systems may also be used as a means of protecting crops from frost, suppressing the growth of weeds, preventing soil consolidation, cooling livestock, and controlling airborne dust. |
