Having established the correspondence with experiment, the widely varying water content from simulation can be used to establish trends over a wide range of conditions, including those that may be inaccessible experimentally. We observe that the diffusion coefficient of inorganic ions increases with the water weight in the cell wall of woody plants. At low water weight, akin to low moisture content, the diffusion is slow (~ 10 -9 cm 2 /s) but grows by almost three orders of magnitude (10 -6 cm 2 /s) for wood with 30 wt.% water. The wide range observed in the diffusion of ions can be attributed to the interactions between inorganic ions and the local secondary cell wall environment with different water weights. As the water weights increase, the ions appear in a more hydrated environment, and diffusion approaches values observed for bulk diffusion in solution.
