Grazing stubble benefits sheep and next season crops.. Stubble has always played a part in the Sinclairs' livestock enterprise, but the family began to have concerns about the impact sheep were having on soil structure during the Millennium Drought... During the past six years their country in southern NSW has experienced productive seasons creating a greater stubble biomass...

Residue management has less impact on stored subsoil water availability than summer weed control... Moisture from rainfall events of 25-30mm between November and April is often still available in the soil at seeding... Modelling of sandy soils, where there is good weed control, shows that most of the moisture received in rain falls of 50mm and 100mm from November to April is stored in the soil, with only 20-30mm lost to evaporation...

If stored water is moderate it may pay to wait and store additional water or, alternatively, consider planting a shorter season crop with lower water requirements... Well managed weed control also plays a vital role in the production of profitable crops as weeds can have a significant impact on yield by competing for moisture, nutrients, space and light as well as harbouring diseases... Crop sequences affect the incidence and severity of major diseases of summer crops, especially those diseases which have several summer, and in some instances winter crop hosts such as RLN, Fusarium graminearum, Macrophomina phaseolina and the Sclerotinia species...

A timely approach to spraying summer weeds is an important practice used to conserve moisture for winter cereal crops and is validated by higher yield potential.. For Mick and Kate Caughey at Merredin in Western Australia's eastern wheatbelt, this means a determined deployment of on-farm practices that conserve stored soil moisture... The trial validated the costs incurred by summer spraying (about $15/ha), Mick says, but also importantly demonstrated what the yield penalty is from not spraying...

" Over the Fence: Soil health key to capturing moisture for profit at Moonie 02 September 2014 Operating a dryland cropping operation in a variable rainfall pattern has put the focus of Moonie farmer Neville Boland squarely on soil health in order to convert every available drop of moisture into crop yield... Mr Boland says the key to success in his climate is fallow efficiency of moisture infiltration and ensuring crops then have the ability to draw that moisture back out...

Recent rains across south-east Australia will provide valuable soil moisture for the 2015 season, but only if summer weeds are kept in check... Where summer weeds were well controlled, we saw a double in yield potential, from two to four tonnes per hectare, which was caused by the additional nitrogen that was available to the crop," he said... Controlling summer weeds has a high probability of improving yields regardless of what type of season 2015 turns out to be," Mr McMaster said...

Time to tackle moisture robbing summer weeds.. Grain growers are encouraged to control weeds as soon as possible, before they become a larger problem... Controlling summer weeds can also minimise disease and insect issues that can occur when a "green bridge" of weeds and volunteer cereals is allowed to survive over summer...
