Weeds researcher Peter Newman is encouraging growers with autosteer on their headers who burn harvest windrows for weed seed control to move their windrows by one metre each year to minimise the amount of nutrients lost from windrowed stubble... If the header follows a different path each year, the potassium is eventually redistributed across the paddock and only nitrogen is lost, Mr Newman says... With higher fertiliser prices and most headers fitted with autosteer, he says "the game has changed and we need to react "...

Controlling weed seed at harvest may be growers' best line of defence in combatting the on-going battle against herbicide resistance... With headers now dotted across winter crop paddocks in New South Wales and Queensland, the Grains Research and Development Corporation (GRDC) is reminding growers that driving down the weed seed bank is critical to managing herbicide resistance... "Driving down the weed seed bank is growers' best defence against herbicide resistance and that centres on two key considerations - dealing with the weed seeds already existing in the soil and stopping additional weed seeds from entering the soil...

Mr Street runs the Grains Research and Development Corporation (GRDC)- funded GOA and is well aware of the difficult issue of herbicide resistance... "I'm a zero-till cropper; I've got no livestock in the system and it's all winter crop at the moment," Mr Street said... "I took the straw spreaders and the spinners off and made up a cheap chute for the back, which probably cost me $100 in steel and a couple of hours in the workshop and it worked fine," Mr Street said...

Narrow windrow burn offers window to kill weed seed.. "Narrow windrows are ideal as they burn hotter for longer, killing the weed seeds, and they also minimise the area of the paddock that is burnt, leaving enough residue to reduce the risk of erosion," said Dr Walsh, whose work is supported by the Grains Research and Development Corporation (GRDC)... "Narrow windrow burning is ideally suited to the lower rainfall areas in Australia where crop yields are lower it has a role to play for growers in higher rainfall areas, particularly for canola and pulse crops where the risk of fire escapes is not as high," Dr Walsh said...
