Simulated stocks of K in the soil, litter, fertiliser, and canopy compartments in a non-K-limited (+K) stand (a) and in the same K-limited (oK) stand (b). Note differences of the y axis scales for better visualisation.

The extent of the potassium (K) limitation of forest productivity is probably more widespread than previously thought, and K limitation could influence the response of forests to future global changes. To understand the effects of K limitation on forest primary production, we have developed the first ecophysiological model simulating the K cycle an...

... This was necessary since CASTANEA was not originately simulating the hydraulic continuum, and the assumption of a fixed root depth made by CASTANEA was not valid in the studied system. Details on the development of the CASTANEA-MAESPA coupled model can be found in (Cornut et al., 2022a;Cornut et al., 2022b). A schematic overview of the model is given in Figure 1. ...
... Simulations were compared with measured biomasses for a five-year rotation. Notably, the CASTANEA-MAESPA model also simulates the K cycle, as described in (Cornut et al., 2022a) which also allowed to test the impact of rainfall reduction on biomass production under K omission. ...
