The authors of this paper note in the conclusion: “While the farm labour resource is complex, awareness of issues that influence the need for labour at different times of the year, such as  the diversity and intensity of cropping systems can directly assist farm resource planning.  Efficient use of available labour can also have bearing on the selection of appropriate crop sequences and cropping intensities."

  • Cropping intensity had a significant effect on labour requirements
  • Diverse rotations may create higher labour demand and peak demands that may limit the adoption of diversified crop rotations in some farm businesses
  • In moderate and lower rainfall environments, crop sequences with higher intensity may yield lower returns per unit of labour (i.e., more than 38% less) than those with lower crop intensities
  • Cropping intensity is a critical determinant of labour organisation in the northern grain growing zone, more so than cropping diversity.

Letters on top of the bars represent High intensity (HI), Moderate Intensity (MI), Low Intensity (LI), High diversity (HD), and Low Diversity (LD).
