Learn how pivot irrigation can be a smarter and more cost-effective way to irrigate a variety of key crops around the world, including corn, soybeans, potatoes, biofuels and more. We are only considering the effect of the size of the pivot span pipes in these examples. Goal: To maximize the benefit of a constrained water supply, and to help center pivot irrigators apply water more efficiently. Irrigation decision-making tools such as irrigation scheduling programs and soil moisture sensors are available to improve the irrigation water use efficiency. It is also sometimes called central pivot or circle irrigation. Sprinklers use anywhere from 0.27 to 30 gallons of water per minute and they only need 6 to 20 psi to operate, depending on the model selected. Energy use can also be reduced by lowering the operating pressur irrigation system. 1" Application Time: Calculate the irrigation time to apply one inch of water with a center pivot. With this method, a circle-shaped area around the pivot is watered, and this is often the cause of circular patterns seen in aerial photos of cropland. Percent Timer Setting: Use this calculator to calculate an approximate timer setting to apply a particular depth. The machine moves in a circular pattern and is fed with water from the pivot point at the center of the circle. The amount of water applied can be adjusted by changing the speed of the system and pivot center systems can also be used to apply types of fertilizers and pesticides.
