SPACSYS: Integration of a 3D root architecture component to carbon, nitrogen and water cycling—Model descriptionL.Wu,M.B.McGechan,N.McRoberts,J.A.Baddeley and C.A.WatsonEcological Modelling, 2007-24-01 View paper
The model is a mixed dimensional, multi-layer, field scale, weather-driven and daily time-step dynamic simulation model. It includes a plant growth and development component, a nitrogen cycling component, a carbon cycling component, a phosphorus cycling component, plus a soil water component that includes representation of water flow to field drains as well as downwards through the soil layers, together with a heat transfer component.
