{"access":"PROSUM is open access: available to use at no cost by request to the model owner.","capabilities":"PROSUM is a dynamic process model that predicts nutrient uptake, net primary productivity and litterfall at monthly timesteps for a range of European natural and semi-natural ecosystems (including woodland, arable, heathland etc).  It is based on law-of-the-minimum except that: (a) plants can store excess nutrients up to a stoichiometric limit (luxury uptake); and (b) rather than only modelling nutrient availability, nutrient acquisition is specifically modelled on the basis of soil exploration by roots and mycorrhizae.  PROSUM uses the CSMP design pattern to allow easy integration with other dynamic models, and it uses modern Fortran's matrix-algebra capabilities to streamline the code and speed up execution.","description":"PROSUM predicts the effects of water and nutrient (nitrogen, phosphorus, potassium) availabilities, and of land management, on vegetation growth, biomass and litter production.  It is used by researchers to explore effects of environmental change on plant growth, crop yield, plant biomass and litter production (including how below-ground litter and exudates control soil carbon stocks).
