What is a pivot irrigation system?
Pivot irrigators, also known as center-pivot or circle irrigators, are rotating machines that water crops using sprinklers. The irrigation method is highly efficient and irrigates crops in a circular area around the system’s pivot point.
How many acres does a pivot irrigate?
How many acres can you cover with a pivot? 400m long pivots are the most common length. With an end gun operating a 400m pivot could effectively irrigate up to 140 acres under good wind conditions. A 500m pivot can cover up to 220 acres in low wind conditions.

How much land can a center pivot spray irrigation system irrigate?
Center pivots are available to irrigate from 5 to 500 ac (2 to 200 ha) although a typical machine will generally irrigate about 125 to 130 acres (50-52 ha) . Economic considerations usually limits their application to irrigated areas larger than 50 ac (20 ha).
Why is center-pivot irrigation used?
They allow farmers to irrigate crops with a fraction of the labor required by traditional methods and do it with closer control of when and how much water they applied. As a result, center pivots can efficiently water an entire field and meet the crop’s irrigation needs while using less water.
How much water do you need to run a pivot?
Most center pivots are designed to be capable of applying 0.3 inches over 24 hours at 6 gpm/ac, meaning you could potentially apply just over 2 inches in a week. Two inches per week or 9 inches in a month is more than enough water to meet a crop’s water use requirements in the humid East.
Is center pivot irrigation expensive?
Center pivot irrigation is a common technique in farming, yet it has the highest costs. Diesel alone can cost up to $25,000 yearly for 15 acre-inches per center pivot system. Farmers have enormous pressure to reduce costs and save water, but it’s not easy without jeopardizing crop quality and yield.
How many gallons per minute does a center pivot use?
What is the size of a pivot irrigation system?
Center Pivot Irrigation (Draft July 2001) Page 17. 24 to 38 inches (610 to 965 mm) in height and 11 to 17 inches (280 to 430 mm) in width . Generally, narrow larger diameter tires are used on heavy clay or loamy soils while wider tires are used on lighter sandy soils for greater flotation.
How centre pivot irrigation system improves crop yield?
The results show that by using high efficiency irrigation system like centre pivot way of irrigation for seed multiplication activities is much improved as compared to other irrigation ways. Improved crop yield with high-quality water use effectiveness under centre pivot irrigation scheme due to its features of high efficiency has been discovered.
What are the different types of centre-pivot irrigation systems?
Centre-pivot irrigation systems can be equipped with different types of emitters. These include mid-elevation spray application (MESA), low-elevation spray application (LESA) and low-energy precision application (LEPA) systems (New and Fipps, 2000).
