In many forms of LID practice, the dominant mechanism reducing the loading of phosphorus, is the significant volume reduction achieved.

===Chemical control===

For infiltration practices an 'amendment' or chemically reactive 'additive' can help to retain even more phosphorus.

For infiltration practices an 'amendment' or chemically reactive 'additive' can help to retain even more phosphorus.  Typically these components would make up 5 to 10% by volume of the filter media mixture.

To help ensure LID BMPs sustain healthy vegetation cover while not contributing substantially to nutrient loading of receiving waters, the quantity of extractable (i.e., available) P in the soil component needs to be measured and compared to design specifications or acceptance criteria.
