To quantify how paddock stubble load and weed burden during summer can affect soil water, nutrients and subsequent crop yield.
Key messages
Conserving summer rain is one of the most effective ways of improving crop yield.
Summer weeds have the biggest impact on how much summer rain is stored and made available to crops.
The presence of stubble has never been shown to have a large positive effect on the storage of summer rain in southern Australia, but it might lengthen the sowing window after the break and improve establishment.
