Fig. 1.

Electrical conductivity (EC, dS m−1) of soil irrigated from a subsurface drip or sprinkler system with saline, moderately saline, or potable water. Data are pooled over soil depths from 0- to 10- and 10- to 20-cm depths. Letters denote the differences (P < 0.05) in EC between the two irrigation systems separately for each sampling date.

 


Fig. 2.

Sodium content (mg L−1) of soil irrigated from a subsurface drip or sprinkler system with saline, moderately saline, and potable water. Data are pooled over soil depths from 0- to 10- and 10- to 20-cm depths.

 


Fig. 3.

Electrical conductivity (EC, dS m−1) in soil at 0- to 10- and 10- to 20-cm depths irrigated from a subsurface drip or sprinkler system. Data are pooled over three water qualities (potable, moderately saline, and saline). Letters denote the differences (P < 0.05) in EC between the two irrigation systems and two depths separately for each sampling date.

 


Fig. 4.

Sodium content (mg L−1) in soil at 0- to 10- and 10- to 20-cm depths irrigated from a subsurface drip or sprinkler system. Data are pooled over three water qualities (potable, moderately saline, and saline). Letters denote the differences (P < 0.05) in Na content between the two irrigation systems and two depths separately for each sampling date.

 


Fig. 5.

Sodium adsorption ratio (SAR) in soil at 0- to 20-cm depths irrigated with saline, moderately saline, or potable water. Data are pooled over two irrigation systems (subsurface drip and sprinkler) and two sampling depths (0–10 and 10–20 cm). Letters denote the differences (P < 0.05) in SAR between the three water qualities separately for each sampling date.

 


Fig. 6.

Sodium adsorption ratio (SAR) in soil at 0- to 10- and 10- to 20-cm depth. Data are pooled over two irrigation systems (subsurface drip and sprinkler) and three water qualities (potable, moderately saline, and saline). Letters denote the differences (P < 0.05) in SAR between the two depths separately for each sampling date.

 


Fig. 7.

Electrical conductivity (EC, dS m−1), Na content (mg L−1), and sodium adsorption ratio (SAR) in soil at 50- to 60-cm depths irrigated with saline, moderately saline, or potable water. Data are pooled over two irrigation systems (subsurface drip and sprinkler). Letters denote the differences (P < 0.05) in EC, Na, and SAR between the three water qualities separately for each sampling date.

 


Fig. 8.

Visual quality of warm-season turfgrasses during spring, summer, and fall in 2005, 2006, and 2007. Data are pooled over nine cultivars, three water qualities, and two irrigation systems. Error bars indicate the standard error of the mean.
