ResumoPhosphorus (P) reaches soils through both pedogenic and anthropogenic sources. This chapter provides a brief overview of the major sources and the dynamics of common P compounds and trace elements in soils and describes processes by which these P compounds act as a source for the mobilization and as a sink for the immobilization of trace elements. As land treatment becomes an important waste management practice, soil is increasingly being seen as a major source of trace elements reaching the food chain, mainly through plant uptake and animal transfer. The chapter discusses the practical implications of P-trace element interactions in relation to the potential value of P compounds in the natural remediation of trace element-contaminated soils. P-induced zinc deficiency is probably the most widely examined P-trace element interaction in the soil-plant system.
