Trial location(s) Loxton, SA
Weed control using narrow windrows vs EMAR chaff deck locations
Aims

To investigate the impact that two different harvest weed seed control (HWSC) methods – narrow windrowing of header trash and the Esperance Mobile Ag Repairs (EMAR) chaff deck – have on reducing the weed burden in the following crop.

Key messages
  • Concentrating the header trash into rows prevents spreading of weed seeds across the paddock. Additionally, it allows for site specific weed management and weed seed destruction through strategic burning.
  • A low cutting height (10cm) can allow greater than 95% weed seed capture and placement
    into rows. However this harvest height can impact harvest cost, speed and efficiency.
