The N14CP model integrates C, N and P cycling in semi-natural and agricultural environments. The model tracks C, N and P pools in total vegetation biomass, topsoil (upper 15 cm of soil) and subsoil layers on a quarterly (3 monthly) time-step. It has been applied at site scale across Europe (temperate climates), and within the UK at regional and national scale. The model is implemented within Matlab.
