Such media contains phosphorus to support plant growth; however, the amount of phosphorus should remain low to avoid substantial leaching and nutrient contribution to nearby receiving waters. The organic matter in the media, as well as deceased plants can decompose and release both organic and inorganic phosphorus. This can increase concentrations in outflow, rendering LID facilities an exporter of nutrients instead of a treatment feature (Bratieres et al. 2008<ref>Bratieres, K., Fletcher, T. D., Deletic, A., & Zinger, Y. A. R. O. N. (2008). Nutrient and sediment removal by stormwater biofilters: A large-scale design optimization study. Water research, 42(14), 3930-3940</ref>). Therefore, it is important to measure the phosphorus content of LID media and/or bulk materials such as [[compost]], and [[topsoil]] and ensure that it is within appropriate design specification range. '''Extractable phosphorus''' is the portion of soil phosphorus that is easily available to organisms like plant and algae and is of immediate concern to water quality in large amounts, so should be included in the parameters tested. '''Extractable phosphorus''' testing is commercially available from soil testing laboratories servicing agricultural and horticultural industries.
