Microscale Heterogeneity Explains Experimental Variability and Non-Linearity in Soil Organic Matter Mineralisation
a) The components of the physiological based fungal model describing mineralisation of organic matter in soil. State variables are circles and arrows indicate transformations. Dotted lines represent processes driven by Michaelis Menten (MM) kinetics. b) A snap shot of fungal biomass (blue) initiated from the right hand plane and distributed through the pore volume (transparent gray pixels) in relation to POM (brown pixels) at t = 150hrs; the fungal biomass shown is the sum of the three types (NIB, IB, IR) as in 1a.
