Relative concentration (

z
(cm) within a soil at various times for
P
= 10,
20, and 60 (
v
= 0.5, 1.5, and 3.0 cm, respectively). Solid curves were obtained using the Brenner
solution, open circles using the Clearly and Adrian solution, and closed circles the Lindstrom
et al. solution. (From Selim and Amacher, 1997. With permission.)
