Biomass holds key for stock grazing timing.. Biomass assessments should be used with phenology rules of thumb in deciding when to remove stock from crops... "In most of south-eastern Australia, where wheat yield averages are around 3 to 4t/ha, there is often excess biomass, so by locking up the crop at an appropriate stage, growers can get the benefit of grazing without a yield penalty," he says...

Producers can increase net returns in dual-purpose crops by up to $500 a hectare and achieve other benefits including weed control through careful grazing management... While producers must obviously weigh up the economics of using dual-purpose crops for their forage or grain value, trial work funded by the Grains Research and Development Corporation (GRDC) and undertaken by CSIRO Agriculture has identified ways of optimising grain yield and grazing potential... "If producers are grazing beyond stem elongation, they should manage stock to protect developing reproductive structures and leave more residual biomass to avoid a yield penalty," Dr Sprague said...

Declining soil organic matter is resulting in declining organic reserves of nitrogen (N) and sulfur (S), while nutrient removal has also depleted the soil minerals providing slow release reserves of phosphorus (P) as well as K. In most situations we have a reasonable ability to assess and meet N demand, but P inputs continue to be at rates << the rate of removal in grain while K and S inputs are non-existent... At both sites, yields were ~800kg/ha higher when K (Warra) or S (Brookstead) was added in addition to extra P. These responses were quite substantial (16% - 26% increases over adding P alone), and compared to the commercial practice at Brookstead, addressing the combined P and K limitations raised yield potentials by ~50%... The sites will be monitored over coming seasons, and are part of a network of trials across northern NSW and southern and central Qld assessing the responses to addressing multiple nutrient limitations, in addition to examining the most appropriate application strategies for the different nutrients...
