Several industries produce by-products capable of sorbing phosphorus (P) that are typically placed in a landfill. These P sorbing materials (PSMs) can reduce soluble P concentrations when added to animal manure, thereby reducing the potential for non-point P transport to surface waters after land application of the manure. Addition of PSMs to manure also provides a beneficial re-use for the by-product material. This chapter reviews and discusses the use of PSMs as manure amendments to reduce soluble P concentrations. The by-product PSMs can generally be separated chemically into two groups: iron/aluminum and calcium/magnesium. However, the ability of a PSM to reduce manure soluble P concentrations is a function of the chemistry of both the PSM and the receiving manure.
