( Fry and Huang, 2004 ). Leaf firing provides a good assessment of overall turfgrass drought resistance under field conditions when the drought stress treatment begins with the soil at field capacity throughout the root zone ( Beard and Sifers, 1997

improved soil physical properties ( Klock-Moore, 2000 ). Recent evidence indicates that biosolids may contain BAS that enable crops to withstand environmental stresses (e.g., drought, salinity, pathogens) and/or positively affect crop growth and quality
