Cultivation to incorporate lime can be more economic than topdressing where: Ca in the 0-10cm layer is well below the recommended 5.5 Ca in the 10-20cm layer is well below the recommended 4.8.. Researchers are starting to devise economic and productivity parameters around cultivating to incorporate lime on acidic soils, rather than topdressing lime... Craig says it is most likely that incorporating lime with cultivation did not lift yields above those achieved with cultivation alone in this first year of the trial because only a small proportion of soil was ameliorated by the one-way plough...

Get lime in your firing line this summer.. Higher quantities of agricultural lime are needed to achieve these results and Mr Gazey said the best product was the cheapest per unit of neutralising value delivered and spread on farm... Long term WA trial data shows top-dressed lime can take five or more years to significantly increase subsurface pH below 10cm...

The grower group 'technical audit' of 61 farmers in Western Australia's northern grainbelt was funded by the Grains Research and Development Corporation (GRDC) and tracks the adoption of practices relating to management of variation in soil types and yield potential, soil health and innovative enterprise... "In the case of auto-steer - used by 92 per cent of growers - this adoption has been rapid; on average the farmers had only just used this technology for the first time in 2006," she said... "Some growers adopted these practices in the past but are now scaling down or no longer using them due to issues such as reduced crop yields and poorer crop establishment in the case of zero-till," Ms Hollamby said...

Some of the researchers from the More Profit from Crop Nutrition phase II project who recently met in Perth: (from left) Margaret Roper from CSIRO, Liam Ryan and Ross Brennan from DAFWA, Professor Zed Rengel from UWA, Roger Lawes and Elliot Duncan from CSIRO, Kelly Ryan and Craig Scanlan from DAFWA, and Louise Barton from UWA... The GRDC's More Profit from Crop Nutrition phase II program (MPCN II) aims to help growers optimise returns from fertiliser and nutrition investments by improving: the nutrient-use efficiency of crops through plant breeding; the capacity of soils to free-up and supply nutrients; the match between N, P, K, S and micronutrient applications and crop needs; and fertiliser and adjuvant product formulation and design... Researchers from the Department of Agriculture and Food, Western Australia (DAFWA), the University of Western Australia (UWA), Murdoch University and CSIRO are collaborating on 26 key national projects through MPCN II...

Trials by the Northern Grower Alliance and funded by the Grains Research and Development Corporation found that adding nitrogen to crops did not have any impact on yield, making the additional cost and potential loss in nitrogen (N) fixing ability a double hit... Northern Grower Alliance Research Manager Lawrie Price said the results were fairly conclusive, with none of the research sites showing any significant increase in yield to N application rate... "It is possible that during a wet season it might be of benefit so research would need to be conducted during a wet year to draw any conclusions about those conditions," Mr Price said...

Regional cropping issues reinforced during Panel tour.. The spread of herbicide resistant weeds, crop nutrition knowledge gaps, the impact of recent frosts and beet western yellows virus, as well as the need to attract and retain the next generation of growers, advisers and researchers, were key topics raised with Panel members during their tour of parts of the southern cropping region... Mr Pengilley said not only did the tour provide Panel members with an enhanced appreciation of the issues confronting growers, but it also enabled them to validate current GRDC-funded research to ensure it was going to deliver practical outcomes for growers...

More than 100 growers and advisors attended a recent More Profit from Crop Nutrition (MPCN) workshop near Kingaroy to learn about soil nutrient management and its critical function in a healthy and profitable farming system... "Many growers are now realising that we have to replace nutrients that we have taken or are taking out," Dr Klepper said... Workshop attendees were advised that nutrient testing needed to be conducted separately at appropriate frequencies - N testing should be carried out on a crop-by-crop basis, K and S levels should be checked regularly while P levels can be checked at 3 to 5 year intervals as long as the deeper layer is checked and growers use the Colwell and BSES methods...

Greg said, despite receiving no extra growing season rainfall, the top performers fared better financially and produced crops with higher yields per hectare in good and bad seasons compared to the low performing group... Greg said a 10% increase in fertiliser efficiency could boost profits by $5.05/ha - or about 10% - for the top performers and higher still for average eastern wheatbelt growers... 2. Freight and post farm gate costs Grain freight is high due to the distances involved, but Greg said there was some potential for savings in back-loading...

Grain growers eager to learn more about nutrient management on farm are invited to attend the More Profit from Crop Nutrition roadshow, being held at different locations through the northern region during July and August... Presented by the Grains Research and Development Corporation's (GRDC) More Profit from Crop Nutrition (MPCN) project in partnership with Queensland Department of Agriculture and Fisheries (DAF) and Birchip Cropping Group (BCG), the roadshow will bring together industry experts, successful farmers and local advisors to look in depth at the balance between soil nutrient balance and crop profitability... Crop nutrition can improve the return on investment from fertiliser inputs by improving the nutrient use efficiency of crops, improving the capacity of soils to supply nutrients, reducing the soil's propensity to lose or lock-up nutrients and develop improved fertiliser product formulation and design including the use of potentially valuable low cost and waste inputs...

A new Grains Research and Development Corporation (GRDC) publication brings together recommendations from 14 projects across Australia, collating crop nutrition information in one handy resource... The GRDC Ground Cover supplement, Making crop nutrition more hit and less miss , includes features on economic assessment of inputs, the impact of plant breeding, novel solutions such as biochar, and tools for nutrient availability...
