Irrigation Pumping Plant Efficiency
Rising energy costs have increased the cost of pumping to the point that many farmers are finding irrigation to be unprofitable or only marginally profitable. Fortunately, however, pumping costs are an item that farmers have some degree of control. Pumping costs often are higher than they need be for two reasons: 1.) more water is pumped than is necessary, and/or, 2.) the pumping plant operates...
متن کاملPhosphorus losses in furrow irrigation runoff.
Phosphorus (P) often limits the eutrophication of streams, rivers, and lakes receiving surface runoff. We evaluated the relationships among selected soil P availability indices and runoff P fractions where manure, whey, or commercial fertilizer applications had previously established a range of soil P availabilities on a Portneuf silt loam (coarse-silty, mixed, superactive, mesic Durinodic Xeri...
متن کاملAccuracy of Irrigation Efficiency Estimates
Evaluation of actual irrigation system perfonnance should rely on an accurate hydrologic water balance over the area considered. In a companion paper, water uses are categorized as consumptive or noncon sumptive, and beneficial or nonbeneficial. Real perfonnance is based on water uses over a specified period of time, rather than observation of a single irrigation event (with associate potentia...

متن کاملIrrigation Increases Inorganic Carbon in Agricultural Soils
Inorganic C reactions are among the most important chemical reactions that occur in irrigated soils and may contribute to the total amount of C sequestered in those soils. Because CO2 can escape from soils to the atmosphere or return to precipitate carbonate minerals, soils are open systems with regard to inorganic C. We measured inorganic and organic C stored in southern Idaho soils having lon...
