Abstract/Contents:Presents a study conducted during 2008 by Colorado State University to "(1) determine spatial and temporal salinity accumulation patterns in soil profiles on golf course fairways with effluent water irrigation" and "(2) evaluate different management practices for reducing sodium and salt accumulation in the soil." Details materials and methods used during the study, noting that the researchers studied "salinity accumulation patterns on four fairways for two effluent water irrigated golf courses using two different types of sensors: 5TE sensor (manufactured by Decagon Devices) and Toro Turf Guard Dual Level (TG2) sensor." Notes that "temporal and spatial accumulation patterns were measured using a network of in situ soil sensors located at two depths." Reports that "results from this study suggest that soil salinity and soil organic matter content did not increase at most of the sample sites over the 5-year period. The average soil exchangeable sodium percentage (ESP) increased from 2.65% [percent] in 2004 to 5.35% in 2009." Concludes that "at the experiment conditions, sodicity is the primary concern when effluent water is used for irrigation. The average soil ESP and SAR [sodium absorption ratio] values approximately doubled over the 5-year period."

USGA Summary Points:At the experiment conditions, sodicity is the primary concern when effluent water is used for irrigation. The average soil ESP and SAR values approximately doubled over the 5-year period Fairways irrigated with effluent water exhibited an increased soil pH Significant linear correlation was observed between 5TE salinity sensormeasured soil salinity and Turf Guard measured soil salinity vs. saturated paste extracted soil salinity Accumulation of salts appears to relate to soil water content (drainage effectiveness), soil texture, and soil compaction level Soil aerification and gypsum addition effectively prevented a significant increase in soil ESP at the hallow soil depths (0-40 cm)
