System capacity is the main criterion the pump, pipes and sprinkler design are based on, and for a given CPLM can be calculated as follows: pump flowrate (ML/d) 100 area irrigated (ha). Annual report table generation to document successful nutrient management. (optional), Schedule Interval:
A CPLM with a marginal system capacity requires a high level of management to avoid productivity loss, and major crop losses could occur with a breakdown or power outage. The System Capacity should be sufficient to meet the crop water requirements for extreme ET0 events. <
8. System capacity is the maximum depth of water that can be applied to the entire irrigated area in one day, (a system capacity of 12mm per day day means the machine cannot apply more than 12mm in one day over the entire irrigable area. No land leveling needed: When using center pivot and linear irrigation, there is no need to level cropland, as is required when using flood irrigation, which means that precious, nutritious topsoil is not lost. Download and fill in the data sheet below so we can perform calculations helped by the latest software. Three days is generally considered to be an appropriate interval (Foley, 2008). The accuracy of the calculator is not guaranteed. You can effectively operate center pivot irrigation sprinklers at 10-20 PSI, which is significantly lower and more efficient than previous generations of sprinklers. End of Pivot.

The peak pasture water requirement used in calculating system capacity is not the highest daily ET0 but the highest average daily ET0 likely to occur over several days. Speed setting is included for your reference purposes if outputs are emailed. D 9
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 (Fig. The center pivot irrigation systems INTRODUCTION The center pivot system consists of one single sprayer or sprinkler pipeline of relatively large diameter, composed of high tensile galvanized light steel or aluminum pipes supported above ground by towers move on wheels, long spans, steel trusses and/or cables (Figure 10.1). That means a system able to apply 8mm/day is not able to keep up with crop water demand on three occasions in a typical season, where 9mm/day is rarely exceeded. 1" Application Time: Calculate the irrigation time to apply one inch of water with a center pivot. 8463 18
