| Soil acidification is one of the major forms of soil degradation in higher rainfall areas of the tablelands of NSW. A grazing experiment was conducted near Sutton, NSW, to assess the effect of various rates of superphosphate, lime, sewage ash and stocking rates on wool production and sustainability between 1999 and 2008. The results from the discounted cash flow analysis show that the net present value of the treatment without lime, the lower rate of superphosphate and the lowest stocking rate returned the highest net present value of $266.30/ha. Raising the application of superphosphate from 125kg/ha every two to three years to 250kg/ha every year on un-limed and limed soil reduced the net present value by $278.70/ha and $249.30/ha, respectively.

| The western NSW rangeland is the pastoral zone of NSW, with increasing abundance and distribution of feral goats (Capra hircus). Feral goats are generally viewed as agricultural pests impacting on agricultural production and natural resources but they are also valuable economic resources that generate income for many pastoralists. This paper presents an economic analysis of alternative feral goat management strategies in the western NSW rangelands. We used benefit‐cost analysis to evaluate the Net Present Value (NPV) and Benefit Cost Ratio (BCR) of feral goat management strategies including do‐nothing, opportunistic harvesting, ‘value added goats’ and establishment of goat‐proof fencing on representative properties in the Bourke, Cobar and Broken Hill... |

| Soil acidity is one of the major farm management problems on the Southern Tablelands of NSW. Soil acidity occurs naturally and yet some agricultural practices exacerbate the process through nitrification, leaching, removal of produce and accumulation of organic matter in the soil. A grazing experiment was conducted between 1999 and 2008 near Sutton, NSW, to assess the impact of various combinations of lime and superphosphate application, and stocking rates, on the profitability and sustainability of wool production on the Southern Tablelands. The profitability of 15 alternative experimental treatments was assessed using the discounted cash flow analysis method for a Merino wether enterprise. The results revealed that the highest net present value was... |
