<strong>Compost</strong>
 
<p>Compost is the most widely used organic component. It's use in bioretention facilities is well established and documented.  Low-phosphorus composts should always be sought for use in low impact development facilities including bioretention. These are typically created from feedstocks including yard, leaf, and wood waste, and must exclude manures, biosolids, and food scraps.<ref> Hurley S, Shrestha P, Cording A.

<p>Even low-phosphorous composts are known to export phosphorous over many years. The use of compost is not recommended in watersheds for which phosphorous pollution is a concern. There are three alternatives which have undergone field study, each of which has a number of benefits and potential concerns:
