Low available phosphorus composts are typically created from feedstocks including yard, leaf, and wood waste, and excluding manures, biosolids, and food scraps.<ref>Hurley S, Shrestha P, Cording A.

===Organic component alternatives===
Even low-phosphorus composts are known to export phosphorus over many years. The use of compost is not recommended in nutrient-sensitive watersheds where phosphorus pollution is a concern, or an [[Additives| additive]] to enhance nutrient retention of the media should also be included. There are a number of alternative sources of soil organic matter which have undergone field studies which have benefits and potential concerns:
