Improving crop water use and yields in the southern Mallee locations
Aims
  • To determine the spatial variability of crop production within paddocks.
  • To estimate the amount of water which is not being used by the crop.
  • To develop agronomic solutions to increase water use and reduce the amount of water bypassing the root system of a crop.
Key messages

Yield variability across the 22 focus paddocks in the project was moderate to very high. Yield variation needs to be managed to minimise the significant economic losses experienced in low performing parts of a paddock. We found very good correlations between soil EM38 maps, satellite imagery of crop vigour and crop yield at harvest. Utilising our knowledge of how the crops grew this season together with the precision farming tools available we will develop management plans in each of the focus paddocks to improve water use, yield and economic return.
