Conservation practice effectiveness in the irrigated Upper Snake/Rock Creek watershed
Provedor de dados: 18
Autores: Bjorneberg, D.L.; Westermann, D.T.; Nelson, N.O.; Kendrick, J.H.
The Upper Snake River/Rock Creek Conservation Effects Assessment Project was initiated in 2005 to determine the effectiveness of conservation practices in an irrigated watershed. Our objectives were to determine water and salt balances and water quality effects of using sprinkler rather than furrow irrigation in the Twin Falls irrigation tract in southern Idaho. Data from the current study were compared with earlier studies conducted from 1968 to 1971. Irrigation water diverted from the Snake River supplied 73% and 83% of the hydrologic input to this 82,000 ha (202,000 ac) watershed in 2005 and 2006, respectively, with approximately 40% flowing back to the Snake River through furrow irrigation runoff, unused irrigation water, and subsurface drainage.

Assessment of Phosphorus Retention in   Irrigation Laterals
Provedor de dados: 18
Autores: Ippolito, J.A.; Nelson, N.O.
Irrigation  laterals  transport  irrigation  return  flow,  including  water,  sediment, and dissolved nutrients, such as phosphorus (P), back to surface water bodies. Phosphorus transformations during transport can affect both P bioavailability and the best management practices selected to minimize P inputs to waters of the United States. The objective of this study  was  to  determine  P  retention  in  three  irrigation  laterals.  Soluble  reactive  P  (SRP) concentrations in lateral waters were increased from 0.08 to 0.25 mg L -1  (0.08 to 0.25 ppm) by constantly injecting a phosphate (PO4) solution for 2.5 hours. Bromide (Br) was used as a conservative tracer to determine dilution effects. Water was sampled at 10-minute intervals, beginning 30...
