| Abstract/Contents: | "Many municipal water supplies in southeast Texas have a relatively high level of Na+ and a low total of dissolved solids. Most soils of this area are dominated by smectitic clays that respond to wetting by swelling, especially when wetted with high Na+ waters of low salinity. This study assessed the degree of Na+ accumulation in southeast Texas soils under irrigated turfgrass and tested models predicting Na accumulation. The Ap, E, and Bt horizons of 18 turf soils in 10 municipal water districts were studied. Irrigation water sodicity (SARiw) and salinity (ECiw) were strongly correlated with soil sodicity (SARe) and salinity (ECe). The SARiw was found to be the best single variable to model soil Na accumulation, but exchangeable Na also increased as a function of years of irrigation. The multiple-regression equation: SARe =-5.16 + 0.53 SARiw + 4.04ln(yr) (R2 = 0.86) best predicted SARe to a depth of 30cm. In the first 10 years, the rate of increase of SARe would increase rapidly, then it would gradually increase after about 10 years and would probably reach equilibrium after 15-year irrigation." |
