TL;DR: Yu et al. as discussed by the authors proposed a double-surface Langmuir isotherm to better capture the non-linear relationships between solution P and labile P pools in the soil.

Abstract: This paper by Yu et al. describes a new algorithm to better represent soil phosphorus sorption dynamics in a terrestrial biosphere model – QUINCY. The authors proposed the use of a double-surface Langmuir isotherm to better capture the non-linear relationships between solution P and labile P pools in the soil. They performed a review on both published data and model assumptions on P sorption. They then compared their simulation against data at a range of P availability sites, performed sensitivity on
