A disease control model for crown rot in Victoria and South Australia (SA) which provides crop management recommendations to reduce the build-up of Fusarium inoculum and avoid sowing into high disease risk situations... Crown rot is highly spatially variable, so intensive and extensive sampling programs were undertaken to assess the the reliability of results produced using current sampling protocols... Intensive stubble and soil sampling was used to assess the scale of spatial variability of crown rot and whether taking soil cores in a row crop was causing "spikes" in results...

Best Practice Guidelines Cotton Farming Systems.. Growers may achieve maximum profitability by applying additional spring-irrigations... The nitrogen requirement of an 8 t/ha wheat crop is approximately 275 kg N/ha studies in 2008 showed that many long-fallow paddocks that lodged had well in excess of this amount of nitrogen available (see Figure 9 (a))...

For grain growers who thought they were already shovelling out the nitrogen every year, 's a sobering thought... Dr Angus says the rate of decrease appears to be linear over 10 to 30 years but after about 50 years, turns out to be curved and soil N eventually flat-lines... Dr Angus says it is likely that gross margins underestimate the profitability of the mixed pasture-crop system by not accounting for other synergies between pastures and crops...

Losses from leaf rust can be reduced by grazing or cutting rusted crops before the disease becomes severe... Adjust the intensity of grazing to avoid the extremes where the crop is either eaten into the ground, or becomes rank and prematurely runs to head... Avoid grazing the crop when the soil is very wet as the crown and root will be damaged and regrowth will be slow and reduced...
