Aims
  • To compare the various tools for determining paddock zones.
  • To determine whether thse zones neededt o be managed differently.
Key messages

This demonstration has shown that there are many tools available to help farmers identify paddock zones. In this case, the farmer was easily able to identify roughly each zone, however from the yield map it is apparent that using the yield maps, to get those zones 100%, slight changes were required. There was little advantage in applying fertiliser in any of the zones, however, emergence issues may have confounded some of these responses. Both P tests (Colwell and DGT) indicated that Zone 2 was responsive to P. There appeared to be a slight increase in yield to P. This was indicated visually during the season, though the difference was thought to be greater and unlikely to be significant. Most importantly, this demonstration has highlighted that you don’t need to invest heavily to practice PA and VR. The farmer identified 80-90% of the variation with the help of other tools. Those tools will prove very important when the zones as less pronounced or in paddocks that have been recently acquired.
