To help growers, consultants, and pivot industry personnel manage and get the most from their system, Nebraska Extension has published the Center Pivot Irrigation Handbook, a 134-page comprehensive guide. Center pivot irrigation systems are the most popular sprinkler irrigation systems in the world because of their high efficiency, high uniformity, ability to irrigate uneven terrain, and low capital, maintenance, and management costs. Center pivot irrigation introduces efficiency along with water management all while having a strong economic value. Both upfront capital investment and ongoing operating costs have to be considered when taking the decision to install a centre pivot. The machine moves in a circular pattern and is fed with water from the pivot point at the center of the circle. Centre pivot performance check When you order a centre pivot, you specify (and will pay for) a particular system capacity, drive train, sprinkler pack and all the various components. Percent Timer Setting: Use this calculator to calculate an approximate timer setting to apply a particular depth. Find high-quality stock photos that you won't find anywhere else. PIVOT IRRIGATION. Center pivot – standard 75-85 Linear (lateral) move 80-87 LEPA – center pivot and linear move 90-95 On sloping sites where soils have a low to medium intake rate, runoff often occurs under center pivot systems, especially at the outer end of the sprinkler lateral. A Visual Basic 6.0 program was utilized in the model application windows. The program was interactive to design a new system and/or evaluate an already designed system. For those who prefer to avoid the use of the computer, the full procedure is detailed in these notes. Pipe Weight Calculator Spreadsheet updated 020411 (XLS; 108 KB). Center pivot irrigation now accounts for approximately 85% of the irrigated land in Nebraska and is the most rapidly expanding form of irrigation in the US. Center pivot irrigation is a form of overhead sprinkler irrigation consisting of several segments of pipe (usually galvanized steel or aluminum) with sprinklers positioned along their length, joined together and supported by trusses, and mounted on wheeled towers.
