Fig. 2. Short-term (24 h), stirred-flow phosphorus release from poultry litter (PL)–treated and untreated Coastal Plain soils (pH 6) after 1 wk of incubation and 24 h of hydration in 2 mM 2-(4-morpholino)-ethane sulfonic acid (MES) buffer and 0.098 M NaCl (pH 6) desorptive solution with a 0.4:7.6 solid to solution ratio. Soil + lit, soil incubated with control litter; soil + al-lit, soil incubated with alum-amended litter. Experiments were not replicated for the short-term study. (A) Evesboro loamy sand, (B) Rumford loamy sand, and (C) Pocomoke sandy loam.
