| Zusammenfassung |
| Site-specific information on land management practices are often desired to
make better assessments of their environmental impacts. A study was
conducted in Lubbock, Texas, in the Southern High Plains of the United
States, an area characterized by semi-arid climatic conditions, to (1) examine
the potential management-induced alterations in soil salinity
indicators in golf course facilities and (2) develop predictive
relationships for a more rapid soil salinity examination within these urban
landscape soils using findings from a portable X-ray fluorescence (PXRF)
spectrometer. Soil samples were collected from managed (well irrigated) and
non-managed (non-irrigated) areas of seven golf course facilities at 0–10,
10–20, and 20–30 cm depths and analyzed for a suite of chemical
properties. Among the extractable cations, sodium (Na) was significantly (p < 0.05)
higher in the managed zones of all the golf facilities. Soil
electrical conductivity (EC), exchangeable sodium percentage (ESP), and
sodium adsorption ratio (SAR), parameters often used in characterizing soil
salinity and sodicity, were for the most part significantly (p < 0.05) higher in
the managed areas. Water quality reports collected over a 22-year period
(1991–2013, all years not available) indicated a gradual increase in pH,
EC, SAR, total alkalinity, and extractable ions, thus supporting the former
findings. Findings from the PXRF suggested possible differences in chemical
species and sources that contribute to salinity between the managed and
non-managed zones. PXRF-quantified Cl and S, and to a lesser extent Ca,
individually and collectively explained 23–85% of the variability
associated with soil salinity at these facilities. |
