Fig. 1. Fall residual soil nitrate in a 1.2-m soil profile for medium (565 kg N ha^-1) and high (848 kg N ha^-1) rates of dewatered biosolids, compared with inorganic N (34–0–0) and zero-N treatments. Inorganic N treatment was 202 kg ha^-1 in 1993, 336 kg ha^-1 in 1994–1996, and 403 kg ha^-1 in 1997–1999. Means within a year followed by a different letter are significantly different at P < 0.05 by protected LSD.
