dc.description.abstract An experiment was started in 1990 to study the effects of reducing input of major nutrients on the long-term sustainability of production from permanent pasture. Four treatments were imposed on a 25-year old pasture dominated by Lolium perenne and Agrostis capillaris namely: CaPKN, CaPK, Ca and no nutrients (Nil). Elimination of nutrients resulted in a rapid change in the balance between grass species in the sward. Tiller density of Lolium perenne declined dramatically after cessation of nutrient inputs whilst that of Agrostis capillaris and other unsown species increased. By 1995 Lolium accounted for only 24 percent of herbage DM production on the Nil treatment compared to 72 percent on the CaPKN treatment. In the same year, the contribution of Agrostis was 41 and 5 percent on the Nil and CaPKN treatments, respectively. Sheep carrying capacity over six years (1991-96) ranked CaPKN>CaPK>Ca>Nil. Ewe stocking rate from May to October 1996 was only 9.3 ewes ha-1 on the Nil sward compared to 25.5 ewes ha-1 on the pasture which received all four nutrients. The results show that maintenance application of major nutrients is essential for sustaining the productivity of improved permanent grassland. en
