Sunflower growers can use aeration drying and cooling to successfully manage a range of seed moisture contents (MC) and temperatures during harvest and storage... Cost of drying during the trial, the first small load of harvested sunflower seed delivered into the Kotzur silo was measured at 13.7 per cent MC... Samples were submitted for analysis and the results demonstrated no increase of ffA levels as a result of aeration drying or cooling (see Table 2.) during the aeration drying and cooling trials outlined sunflower seed was sampled before and after storage from all silos...

Ravensthorpe grower Bevan Tuckett with an instruments station being used to map different soil types for their responsiveness to nitrogen treatments and their water-holding capacity... A SMP is permanently installed and works by sensing moisture in close proximity (about a 10cm radius) to the probe, recording this information and sending it via a cable to a telemetry unit and data logger... More than 50 SMPs have been installed in recent years across WA's broadacre cropping areas in a range of trials supported by GRDC, CSIRO, the Department of Agriculture and Food WA (DAFWA), advisers, grower groups and other industry stakeholders...

" GCTV Stored Grain: Sunflower Cooling 11 March 2014 Specialist Grain Storage agronomist Philip Burrill commenting on aeration cooling of sunflower seed in on-farm storage... Many cases we end up with no storage pests 33.64: by reducing that grain temperature... 92.899: And lastly the venting on top of the silo, we are looking to prevent obviously rain or 98.229: storms from bringing moisture into the storage and at the same time not restrict that airflow 104.2: coming out through that aeration cooling...

Drought years improve growers' use of soil moisture.. From his experience, Peter says the key to moisture conservation, is keeping stubble free of any weeds so as to retain all summer rainfall... For instance, Peter was checking on the likelihood of getting 500mm of rain between January and May for sowing using the CliMate app...

You typically find that the depth to the salt bulge decreases to the west... We have concluded that chickpeas were not as effective as wheat in adjusting yield components under prolonged water stress... The grain yield in the SF early burn and cultivated treatment (2.5 t/ha) was comparable to the other SF treatments in the dry 2002 season despite having the lowest incidence of crown rot infection...

Grain drying and aeration to manage wet grain... Glyphosate is widely used for fallow weed control, particularly on farms using reduced tillage practices... Computer simulations, using a glyphosate resistance model developed by the WAHRI group at UWA, predicted that the probability for ryegrass to develop resistance increased from 0% for conventional wheat system using glyphosate once in fallow to 82% for zero tillage systems with RR crops and greater use of glyphosate...
