Abstract/Contents: | "Increasing demand on fresh water supplies in the arid and semi-arid western US and more stringent wastewater discharge standards have made recycled water a common water source for irrigating golf courses and urban landscapes. This has created the need to study the effects of recycled water irrigation on soil chemical properties. We collected and analyzed soil samples at the commencement (in 2004) and 5 and 11 years after recycled water irrigation on three golf courses, 5 metropolitan parks, 1 school ground, and 1 zoo. Samples were taken at 0-20, 20-40, 40-60, 60-80, and 80-100 cm depths on golf courses and at 0-20 and 20-40 cm depths at other locations. Soil samples were tested for soil texture, soil pH, soil organic matter, soil salinity [soil electrical conductivity (EC)], exchangeable sodium percentage (ESP), Cl and B concentration, and AB-DTPA extracted P, K, Zn, Fe, Mn, and Cu levels. Nitrate-N was determined using flow-injection Cd reduction analysis. Average soil EC was 0.84, 0.88, and 0.98 dS m-1 in 2004, 2009, and 2015, respectively. On average, soil pH was 0.25-0.3 units higher in 2009 and 2015 when compared to 2004. The degree of soil pH increase was greater at deeper than at shallower soil depths. Samples collected in 2004, 2009, and 2015 had an average ESP of 2.65%, 5.35%, and 4.43%, respectively. The increase in ESP suggested that sodicity was of greater concern than salinity when recycled water is used for irrigation. Gypsum application after aerification displaced sodium and reduced ESP at the surface depth (0-20 cm). However, soil ESP increased significantly at deeper soil depths. No increase in soil nitrate-N was observed over 5 and 11 years with recycled water irrigation. Therefore, leaching of nitrogen to the groundwater was not a great concern." |
