Pasture Production
Data source: Dave Barker AgResearch Grasslands Palmerston North New Zealand
The objective was to predict pasture production from a variety of biophysical factors. Vegetation and soil variables from areas of grazed North Island hill country with different management (fertilizer application/stocking rate) histories (1973-1994) were measured and subdivided into 36 paddocks. Ninteen vegetation (including herbage producution); soil chemical, physical and biological; and soil water variables were selected as potentially useful biophysical indicators.
Number of Instances: 36
