" 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 Attribute Information: 1. fertiliser - fertiliser used - enumerated 2. slope - slope of the paddock - integer 3. aspect-dev-NW - the deviation from the north-west - integer 4. OlsenP - integer 5. MinN - integer 6. TS - integer 7. Ca-Mg - calcium magnesium ration - real 8. LOM - soil lom (g/100g) - real 9. NFIX-mean - a mean calculation - real 10. Eworms-main-3 - main 3 spp earth worms per g/m2 - real 11. Eworms-No-species - number of spp - integer 12. KUnSat - mm/hr - real 13. OM - real 14. Air-Perm - real 15. Porosity - real 16. HFRG-pct-mean - mean percent - real 17. legume-yield - kgDM/ha - real 18. OSPP-pct-mean - mean percent - real 19. Jan-Mar-mean-TDR - real 20. Annual-Mean-Runoff - in mm - real 21. root-surface-area - m2/m3 - real 22.
