Figure 2: Leachate soluble reactive P (SRP) concentrations. Leaching events 1, 2, 3, and 4 correspond to 15, 30, 60, and 90 d of incubation. P rate 112 mg P kg−1 (224 kg P ha−1). Error bars represent one standard error. Data represent the average of three replicates. Open symbols represent biological nutrient removal biosolids.
