From this the nutrient application level needed to maintain a given stocking rate can be determined, along with its profitability. Feasible stocking levels and fertiliser application rates are investigated and the optimal combination found, along with the sensitivity of this combination. It is shown that profitability is relatively insensitive to fertiliser level compared with stocking rate.<\/jats:p>","DOI":"10.1155\/s1173912697000035","type":"journal-article","created":{"date-parts":[[2007,3,8]],"date-time":"2007-03-08T07:44:28Z","timestamp":1173339868000},"page":"27-43","source":"Crossref","is-referenced-by-count":1,"title":["Dynamical systems modelling of the interactions of animal stocking\ndensity and soil fertility in grazed pasture"],"prefix":"10.1080","volume":"1","author":[{"given":"I.
