Conserving moisture during summer locations
Aims

To quantify how paddock stubble load and weed burden during summer can affect available soil water, nutrients and subsequent crop yield.

Key messages
  • Weeds have the biggest impact on summer water storage.
  • Over the last two summers, the method of weed control had little effect on moisture storage
  • Even under adequate growing season rainfall, weed control is necessary because weeds tie up and/or prevent significant amounts of nitrogen mineralizing, which cost 0.5t/ha of the canola yield.
