Introduction

Phosphorus (P) is an essential element for both plant and animal life. It provides energy to cells in the form of adenosine triphosphate (ATP), and is a structural component of cell walls (phospholipids) and of nucleic acids (phosphate backbone of DNA and RNA). Biological productivity is heavily reliant on P availability to photosynthetic organisms, which constitute the base of the food chain in both terrestrial and aquatic ecosystems and hence used as a fertilizer to increase crop yield. The biogeochemical processes governing P availability and dynamics in the environment are complex, and vary widely from one ecosystem to another, thus requiring a highly interdisciplinary approach to research.

General Overviews and Textbooks

Unlike other major biogeochemical elements, the global P cycle is unique in that it does not have a significant gaseous component, as phosphine requires a highly reduced environment to be stable. The majority of terrestrial reactive P is originally derived from the weathering of calcium phosphate (e.g., apatite) and other minerals and the conversion of mineral P to dissolved forms. Since P content in rocks is generally low, microbial recycling of organic P forms plays an important role in supporting primary production and controlling ecosystem structure. Overall, the global P cycle has five main components: (1) tectonic uplift of P-bearing rocks (e.g., phosphorite); (2) physical and chemical weathering of rocks and minerals, generating soils as well as particulate and dissolved P forms; (3) P transport to water bodies via rivers, streams, groundwater, and aerosols; (4) P transport to the deep ocean via sedimentation of mineral P and particulate organic matter (marine snow); and (5) P burial in marine sediments and transformations and lithification after burial. The textbooks included below provide overviews of specific components of the P cycle. Schlesinger and Bernhardt 2013 is a comprehensive textbook dedicated to biogeochemistry, with insights into global biogeochemical cycles, including that of P cycle. Libes 1992 and Hansell and Carlson 2002 focus on marine biogeochemistry, with the former including an overview of the marine P cycle and the latter focusing on dissolved organic matter and the dynamics of dissolved organic P. Turner, et al. 2005 focuses on organic P in the environment, from its characterization to the biotic and abiotic processes controlling its reactivity in the environment. Selim 2015 is a compilation of studies examining the role P plays in enhancing or reducing the mobility of heavy metals in soil and the soil-water-plant environment. Nriagu and Moore 1984 is dedicated to P mineralogy, while Shergold and Cook 2005; Notholt, et al. 2005; and Burnett and Riggs 2006 focus on phosphorite deposits across geologic time. Lastly, Zapata and Roy 2004 combines research on the application of phosphate rocks in agriculture.
