Benefits
Center pivot irrigation typically uses less water compared to many surface irrigation and furrow irrigation techniques, which reduces the expenditure of and conserves water. It also helps to reduce labor costs compared to some ground irrigation techniques, which are often more labor intensive. Some ground irrigation techniques involve the digging of channels on the land for the water to flow, whereas the use of center-pivot irrigation can reduce the amount of soil tillage that occurs and helps to reduce water runoff and soil erosion that can occur with ground irrigation. Less tillage encourages more organic materials and crop residue to decompose back into the soil, and reduces soil compaction.

Famous quotes containing the word benefits:
“Through all opposition the personal benefits of the reform [dress] [bracketed word in original] have compensated; but had it been mainly sacrifice, the thought of working for the amelioration of women and the elevation of humanity would still have been the beacon-star guiding me on amid all discouragements.”
—Susan Pecker Fowler (1823–1911)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“One of the benefits of a college education is, to show the boy its little avail.”
—Ralph Waldo Emerson (1803–1882)
