On how many paddocks does PA deliver a return?

摘要

Variable rate technologies and precision agriculture can boost cropping returns. However, not all paddocks generate worthwhile returns. CSIRO, Curtin University and DAFWA have jointly developed an economic calculator to help consultants and farmers decide which paddocks may warrant investment in VRT or PA. In 2008 Michael Robertson found VRT could return around $15 per hectare on a wheat field. However, these returns varied markedly from paddock to paddock and in general, Robertson found that VRT generated high returns when crop yields within the field varied by one tonne per hectare or more.
