Two short courses have been planned in Nebraska to help irrigators better manage their center pivot systems.
The sessions, which are free, will be held Feb. 6 in Gothenburg at the Monsanto Water Utilization Learning Center and Feb. 8 at the Cornerstone Ag & Event Center on the York County Fairgrounds in York.
Topics scheduled for the day-long sessions are:
Performance of center pivots--describing basic center pivot characteristics, efficiency and uniformity and system capacity
Soil water management--understanding soil characteristics and managing soil moisture through tillage and residue practices and using soil moisture monitoring equipment
Matching sprinklers to soil types--using web soil survey and Natural Resources Conservation Service information to select sprinkler packages that minimize runoff
Selecting a sprinkler package for a pivot--evaluating various sprinkler designs for wetted diameter, operating pressure and flow rate
Minimizing pumping costs--evaluating pumping plant performance and determining if repairs are feasible
Crop water use--estimating evapotranspiration, factors affecting ET and relationship between ET and yield.
Water balance, consumptive use and limited irrigation--reducing irrigation water use, deficit irrigation and other limited irrigation strategies
Center pivot technology and variable rate irrigation—new technology to maximize efficiency
Center pivot management—checking for runoff, correct operating pressure and worn sprinkler nozzles
The keynote address in Gothenburg will be given by Chandler Mazour, manager of the Monsanto Learning Center and in York by Ronnie Green, Institute of Agriculture and Natural Resources Harlan vice chancellor.
Those attending can also view irrigation-related displays and get access to web-based soil surveys.
While the event is free, participants are asked to register so that adequate materials and meals will be available.
