Simulating the impact of fertiliser strategies and prices on the economics of developing and managing the Cicerone Project farmlets under climatic uncertainty

摘要: The application of fertilisers to pastures in the high rainfall regions southern Australia has contributed large increases carrying capacity following widespread adoption practice since late 1940s. Recently, shifts worldwide demand for fertiliser inputs have lead rises cost inputs. These increasing costs significant potential ramifications on future management soil fertility and its interaction with persistence profitability sown pastures, especially during periods climatic uncertainty. A dynamic pasture resource development simulation model was used investigate implications rates efficient under framework also allowed investigation how interacts utilisation resources through different stocking rates. In this method Cicerone Project farmlets case study, input were found influence optimal combination rate. Analyses between cost, rate desirable species enabled identification most risk-efficient strategies. grazing industries are discussed.
