The economics of summer weed spraying and effects on soil water and soil nitrogen for the Kwinana East RCSN Zone locations
Aims

To demonstrate differences between sprayed and unsprayed plots from December 2012 to February 2013 for RCSN Kwinana East Port Zone trial locations.

Key messages

A harvest-time knockdown to kill summer weeds has been shown to conserve significant soil moisture prior to seeding in a series of trials across the eastern wheatbelt this year.
