Appropriate Depths of Application for Scheduling Center Pivot Irrigations
Transactions of the ASAE, 1992The center pivot irrigator is faced with a problem of determining the appropriate depth of water application to use for management purposes to minimize both yield loss and water quality degradation. The current study builds on the work of Peri, Hart, and Norum (1979), using the normal distribution of application depth and linear yield and economic ...

Application Rates from Center Pivot Irrigation with Current Sprinkler Types.
2003, 2004, 2005 Pacific Northwest Region Papers, 2005Center pivot sprinkler irrigation is increasing in popularity in the United States due to the low labor requirement and ability to irrigate large fields. The main problem associated with pivots continues to be the inherently high application rates and tendency for runoff and erosion on medium- and fine-textured soils and rolling topography.

Abstract Determining the amount and timing of irrigation events using scientific irrigation scheduling (SIS) may help optimize water use. Soil moisture sensors, commercial irrigation schedulers, and water balance programs are common SIS tools. These three methods were evaluated to test their impact on alfalfa (
