Irrigation Management - A Mechanism for Saving Energy and Water

摘要

Research was conducted to determine irrigation management practices on the various soil textures in Nebraska. The basic objective was to design and select irrigation systems to minimize water and energy requirements. To meet this objective, improved irrigation practices were investigated for more efficient use of water and energy resources. Research has indicated that irrigating at maximum non-erosive stream size and automating the furrow irrigation system, one can reduce the irrigation set time and amount of water applied to acceptable levels. This design criteria substantially increases the efficiency of water and energy used. Research has also shown that the selection of various furrow opening and furrow smoothing practices influences the amount of water applied and should be selected according to the soils infiltration characteristics.
