More than 4.5 million acres in the Pacific Northwest are irrigated with electric-powered sprinkler systems. Center pivots are used on about 1.25 million acres. Irrigation runoff can be a problem on many of these sprinkler-irrigated fields.
The main purpose for irrigating is to supply needed water for crops. Plant growth is dependent on photosynthesis. While the plant exchanges gases with the air for photosynthesis, some water evaporates. Water is taken up from the soil by plant roots to replace
this water. The water leaving the plant...
This “walk-through” worksheet provides a method for making an organized inspection of an entire irrigation system, both hydraulics and hardware. This inspection will help identify components that need maintenance, repair, replacement, or other attention—so that the system will provide the most satisfactory, safe, and efficient performance.
Groundwater is an important resource in
Oregon. As more people depend on groundwater,
some water tables around the State are dropping,
threatening their water supplies. State law
requires that groundwater be managed as a
renewable resource, and that water tables do not
