A large number of natural and anthropogenic processes in our environment are dominated by chemical reactions at the interface between solid and aqueous phases. These reactions include the adsorption…

Soil organic phosphorus: speciation, abundance, and ecosystem implications in a changing climate

Lead Institution

University of California, Merced

Principal Investigator

Asmeret Berhe

Project type

Exploratory Research

Soil organic phosphorus (P) has been identified as a pivotal component of bioavailable P, especially in late stages of ecosystem development. Organic P turnover rate is affected by the stabilization…
