WebSep 19, 2024 · The full method description and data used for crop and forest and grassland is in S1 File. The method used for croplands determines C residues for an entire year. We then distributed the residues monthly. This distribution depends on the distribution of net primary production per month and the life stages of plants. WebThe Hurley Pasture Model is a dynamic, process-based model of carbon and nitrogen inputs, cycling and fate in cool temperate grassland. It covers plants, animals, and soils and their interaction. It simulates the responses of temperate grasslands to the environment (eg light, temperature, daylength, rainfall, CO 2) and to management (eg ...
