How much water does a pivot irrigation system use?
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.
What is the advantage of pivot irrigation?
Benefits. Center-pivot irrigation uses less labor than many other surface irrigation methods, such as furrow irrigation. It also has lower labor costs than ground-irrigation techniques that require digging of channels. Also, center-pivot irrigation can reduce the amount of soil tillage.
Does center pivot irrigation save water?
Only about 50% of water is absorbed using flood irrigation; the other half is lost to evaporation, runoff, infiltration of uncultivated areas and transpiration through the leaves of weeds. With center pivot irrigation, water absorption rates improve to 85-90%.
How many acres are in a pivot circle?
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 far apart are pivot towers?
The distance between towers is called a span. The length of the span can vary between 130 and 200 feet. The typical pipe on the pivot has an outside diameter of 65/8 inches with a wall thickness of 0.109 inches. The pipe and the towers are typically galvanized to prevent corrosion.
How long can a pivot be?

How cold can you run a center pivot?
The usual recommendation is not to run a pivot when temperatures are below 40 degrees. This year, several pivots have been operated below 40 degrees without problem, but keep in mind with low dew points the pivot can ice up when the actual air temperature is well above 32.
How long is a 6 Tower pivot?
The length of the span can vary between 130 and 200 feet. The typical pipe on the pivot has an outside diameter of 65/8 inches with a wall thickness of 0.109 inches. The pipe and the towers are typically galvanized to prevent corrosion.
How do you winterize a pivot?
To winterize your center pivot, drain your pipelines, and make sure you also drain any condensed water from wheel gearboxes and gear motors. In addition, perform normal greasing of parts at least yearly. Steel moving on steel without proper lubrication can lead to unnecessary wear and tear on irrigation equipment.
