The objective was to compare the impact of RM and SD on water quality information [Total suspended solids (TSS), nitrates and nitrites (NO3  <!-->NO2), orthophosphates (ortho-PO4) , total phosphorus (P), and total Kjeldahl nitrogen (TKN)] of irrigation runoff in six agricultural fields for two irrigation events each year during the 2009 and 2010 growing seasons. The sites that were selected for this study used best management practices (BMPs) such as conservation crop rotation, irrigation land leveling, poly-pipe use, irrigation water management, pest and nutrient management. Results illustrate that furrow irrigated fields using poly-pipe and employing RM as a BMP can lead to decreased TSS and ortho-PO4 constituents in surface water runoff, thus, lowering the potential for contamination in the AC watershed. There is still more opportunity to conserve water and reduce nutrient loadings considering that approximately 30% of the applied water was lost to runoff in some farms. Finally, results demonstrate that irrigators can play a significant role in the prevention of soluble N compounds from running off-site and into the AC watershed by monitoring irrigation application, as total runoff amounts from fields decreased in 2010 after the field managers were educated about the amount of water applied and running off the field during 2009.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"3 ","pages":"Pages 25-32"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2014.11.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90169439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using five core metrics – two watershed metrics (percent land use in agriculture and distance to the nearest road from the survey site) and three in-stream metrics (riffle/run quality, dissolved oxygen content and water temperature), a classification model has been developed, useful as preliminary indication as to a stream’s suitability to sustain brook trout populations. Developed via discriminant analysis using Maryland Department of Natural Resources’ historical stream data, two classification equations (Smith–Sklarew equations) can be simplified into one equation, which produces a sustainability statistic (S). Should the five field measurements from the metrics produce a positive “S” value at a given site, then the stream reach most likely favors conditions suitable for sustainable brook trout populations.
