Technical Note: A generic law-of-the-minimum flux limiter for simulating substrate limitation in biogeochemical models
We present a generic flux limiter to account for mass limitations from an arbitrary number of substrates in a biogeochemical reaction network. The flux limiter is based on the observation that substrate (e.g., nitrogen, phosphorus) limitation in biogeochemical models can be represented as to ensure mass conservative and non-negative numerical solutions to the governing ordinary differential equ...

The goal of the note is to document a method of solving nutrient dynamics in biogeochemical models. Specially it focuses on improving numerical solutions of biogeochemical models (specifically soil model) so that 1) negative nutrient concentrations are not simulated and 2) serial access (i.e. microbes have first access, then plants) to nutrients is not required by the different nutrient consume...

General comments The authors describe a new, explicit, first-order accurate numerical integration scheme that is designed to ensure that (elemental) masses are conserved and remain non-negative regardless of the magnitude of the projection timestep. They present a brief summary of prior schemes that have aimed to achieve nonnegativity (but, in some cases, sacrificed conservation). They highligh...
