Compost application to turf grass may influence soil sodicity and salinity and eventually the establishment and growth of turf grass. The objectives of this study were to determine effects of compost source and application rate on soil sodicity and salinity during 29 months after a one-time application to Saint Augustine grass and Bermuda grass turf grown on a sandy loam soil. Extractable soil Na, electrical conductivity (EC), and pH did not differ among compost sources having variable Na and nutrient levels. However, compost application decreased soil Na, EC, and pH compared to unamended ...
