Application of Liquid Animal Manures Using Center Pivot Irrigation Systems, EC778 (PDF - 1.60 MB; 13 pages)
Animal manure management practices are being scrutinized to ensure that the potential for environmental pollution is minimized. Manure from large and small production facilities must be distributed in a manner that limits the potential for surface runoff, deep percolation and drift to off-target areas.
The Center Pivot Water Conservation Project is a partnership to help train pivot irrigators to become more efficient in their water application.
Irrigation System Checkup
Performing regular maintenance of your irrigation equipment should include a pre-season checkup. The expectation should be that component wear happens and it sometimes results in less uniform water application, and increased energy use.
In addition, to reduce the risk that wear and tear will result in untimely breakdowns, worn components should be identified and replaced now so that the systems are ready for use during the growing season. See our checklist.
