Long Term Effects of Effluent Water Irrigation on Soil Nitrate and Phosphorus Profiles under Turfgrass

S.F. Alshammary and Y.L. Qian

Abstract:
This study seeks to determine whether the use of effluent water over time has an effect on the nitrate and phosphorus content of the soil. We took soil samples from six golf courses that have been irrigating with effluent water for various periods of time. On each golf course soil cores were sampled from three different fairways to a depth of one meter and then subdivided into 20 cm increments. Regression analysis was conducted on the averaged values from each golf course to evaluate the relationship between the length of time of effluent usage and soil nitrate or phosphorus content. Results indicate that though there is no significant correlation between the number of years of irrigating with effluent water and the amount of nitrate in the soil, there is a strong correlation between the number of years of effluent irrigation and the amount of phosphorus at the surface 0-20 cm of the soil. The study strongly advocated that proper management of wastewater irrigation and periodic monitoring of soil and groundwater parameters are required to ensure successful, safe, long term wastewater irrigation.
