Abstract
Under what conditions can plants be used to remove phosphorus from common Florida soils? This 5-page fact sheet shows how calculations for the phosphorus saturation ratio and soil phosphorus storage capacity at various soil depths can be used to determine whether to use phytoremediation as a strategy to remove phosphorus from the soil.
