Phosphorus leached (percent of total applied) from Immokalee soil (P rate = 224 kg P ha^-1) as a function of the biosolids phosphorus saturation index (PSI) (trendline and square data points). No P source exhibited significant leaching for the Candler soil, and only Largo materials are shown ("x" data points). The Myakka soil data is from a previous study.
