Catalogue: GRDC 2014 Research Summaries
In 2011, Australian agriculture used a combined 1632 kt of N, P and K to manage soil nutritional constraints to production... Dr Mark Conyers is a Principal Research Scientist of NSW DPI (Wagga Wagga) and has over 30 years experience in soil nutritional chemistry in southern grains farming systems... Dr Conyers is one of several senior nutritional soil scientists around Australia in a similar situation, the retirement of which will substantially reduce the pool of expertise in this field for the entire Australian grains industry. This proposed investment will result in the appointment of a post-doctoral fellow that is jointly funded by GRDC and NSW DPI for the next 3 years (2013-2016) as an understudy to Dr Conyers and will result in a maintained capacity in the field of soil chemistry in relation to crop nutrition...

DAFWA researcher Derk Bakker after digging in a ‘flume’ to measure water run-off and making channels across the trial plot to trap the water... "Non-wetting soils - caused by the presence of waxy surfaces on the sand particles - can be a major impediment to crop germination and productivity in many WA soils, including forest gravels," Dr Bakker said... "While the plough did not greatly improve the wettability of the soil, the cultivation facilitated root growth and improved water penetration, which would have enhanced the accessibility of phosphorus to crops," Dr Bakker said...

Central Queensland grain growers are targeting more precise management of soil nutrition to bolster farm productivity, following workshops in Capella and Biloela last week... The producers in attendance are participants in the Grains Best Management Practices (BMP) program, an initiative of the Queensland Department of Agriculture Fisheries and Forestry (DAFF), the Fitzroy Basin Association and AgForce Qld, which help producers identify pathways to improving on-farm practices to meet industry standards and improve profitability... The workshops were delivered by Chris Dowling from Back Paddock Company as part of the northern region, Nutrition - Training and Extension project, for the More Profit from Crop Nutrition II (MPCN II) Initiative, supported by the Grains Research and Development Corporation (GRDC) and DAFF...

" Date: 13.12.2013 'Lime bank' deposits a good investment.. The Department of Agriculture and Food (DAFWA) now estimates that soil acidity costs up to $500 million annually in lost production across WA's grainbelt... Researchers including DAFWA's Chris Gazey estimate that 2.5 million tonnes per year of lime is needed for the next decade to recover soil pH to the targets of 5.5 in the surface and 4.8 in the subsurface layers and address ongoing soil acidification...

The workshop, supported by the Grains Research and Development Corporation (GRDC), will enable local grain growers to receive expert commentary on the quality of their soils... To be held on August 28 at the Ramblers Football Club, Cummins, the workshop will introduce growers and consultants to the National Soil Quality Monitoring Program, which is funded by the GRDC through its Soil Biology Initiative II (SBI II)... The SBI II program has been able to link with sites being assessed for soil carbon as part of the Soil Carbon Research Program (SCaRP) which is managed by CSIRO and funded by GRDC and the Department of Agriculture, Fisheries and Forestry (DAFF)...

Lake Bolac workshop to explore summer crop options.. The "Making Money From Summer Rainfall" technical workshop at the Lake Bolac Bush Nursing Centre will explore summer forage and summer grain cropping options for the HRZ... The workshop will feature a line-up of expert speakers who will also discuss spring-sown winter canola, utilising summer fallow soil moisture, crop nutrition for forage crops, agronomic management and how to successfully incorporate fodder and grain crops into a farming system," said Mr Midwood, who is also chief executive of Southern Farming Systems (SFS)...

Single tillage events can reduce moisture but may boost yields and profitability in the presence of a high weed burden... Dr Yash Dang, Queensland Department of Science, Information Technology, Innovation and the Arts (DSITIA) senior scientist (soil and nutrient management) says balancing soil moisture and weed control has been a dilemma for growers choosing to use strategic tillage to manage difficult-control-weeds within an established no-till farming system... Dr Dang said grain yields showed little response to tillage and one-time tillage using either chisel or offset disc tended to increase grain yields at all the sites but only significantly at the Condamine site...

Call for croppers to protect organic carbon.. Along with nutrient supply, healthy soils rely on the physical and biological benefits of OC for crops and pastures, such as water holding capacity on lighter soils and disease suppression, he says... Dr Lawrence says in higher rainfall areas (more than 700 millimetres per annum) there is potential to maintain OC at higher levels using an intensive no till opportunity cropping system which relies on converting a high percentage of rainfall into plant growth...
