Part I. Creating a Basic Simulation Model In the discussion about soil organic matter dynamics, Young (1997) mentioned that the loss of organic matter through oxidation follows an exponential decay pattern and that, under constant organic matter inputs, the soil organic matter would reach an equilibrium state. Using a Vensim simulation model, demonstrate that this equilibrium assertion appears to hold true regardless of the oxidation speed or magnitude of inputs as long as inputs are constant. Expected outputs: 1. Stock and Flow Diagram 2. Model Equations 3. Simulation results on the effect of different oxidation speed 4. Simulation results on the effect of different organic matter input values
