12mm/d pivot completing its circle in 24 hours applies 12mm if it completes the circle in 48 hours it applies 24mm. ABN: 33 650 994 522. Growing maize in Kyabram will have three-day average ET0 of 9mm per day with crop coefficient (Kc) of 1.2 when in full canopy. With rising fuel prices it is increasingly important that irrigation systems apply water uniformly in order to achieve maximum benefit from the water applied. 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.

Generally, radius equals machine length plus endgun throw (if present). Reference: Washington State University. However, the appropriate Kc for mature actively growing lucerne, maize or sorghum is likely to approximate 1.2. 0000005205 00000 n
Center Pivot Irrigation. In addition, if the CPLM then breaks down, it can be very difficult to replenish soil moisture levels to maintain optimal production. So the acreage of a circular area is: Acres = * radius_in_feet / 43560 . Per field nutrient loading, based on process wash water nutrient concentration and volume of water applied Pivot name is optional, but included for your ID purposes if links are emailed. Uniformity of application: An even distribution of material can be achieved easily and automatically. $32.79. If the center pivot isn't a full circle, estimate or measure the actual length of the end tower wheel path. The BaseStation3 collects application and flow meter data that can be integrated into the CES Water Sentinel, a standalone, Internet-accessible data management service designed by water management experts to simplify data management at all land application sites. A treatment without irrigation was applied as a control.
While the system capacity is critical to supply the peak crop water requirement, it also determines the operating hours necessary in normal conditions. Posted by .
