PHOSPHORUS IN THE ENVIRONMENT: Natural Flows and Human ...

Abstract Phosphorus has a number of indispensable biochemical roles but it does not have a rapid global cycle akin to the circulations of C or N. Natural mobilization of the element a part of the grand geotectonic denudation-uplift cycle is slow and low solubility of phosphates and their rapid transformation to insoluble forms make the element commonly the growth-limiting nutrient ...
