Soil testing with rake and boot.. Research is updating 'critical soil test values' which is improving interpretation of soil test results and helping Western Australian grain growers make better fertiliser decisions... Findings from crop nutrition research and guidelines to help growers conduct soil testing and apply fertiliser effectively are outlined in a Soil Testing for Crop Nutrition Fact Sheet and More Profit from Crop Nutrition Ground Cover Supplement...

Break crops could hold key to tap soil phosphorus reserves.. University of Adelaide research, funded by the GRDC, on break crops has demonstrated positive effects on phosphorus uptake and yield in subsequent wheat crops... Wheat following a break crop has a greater P uptake and higher yield than continuous wheat rotations...

The Better Fertiliser Decisions for Crop Nutrition Fact Sheet states that inefficient or incorrect use of fertiliser can be a substantial, but somewhat hidden cost, in the cropping operation... The new fact sheets have been distributed to growers with the November-December issue of GRDC's Ground Cover magazine and can also be viewed and downloaded via www.grdc.com.au/GRDC-FS-BFDCN and www.grdc.com.au/GRDC-FS-CropNutrition-Micronutrients ... Caption: The Grains Research and Development Corporation (GRDC) has released two new fact sheets to enhance grain growers' understanding of crop nutrition...

Australian research is beginning to reveal the impact of farming practices on soil microbiology and how this affects the supply of yield-boosting nutrients to crops... Dr Phillips said research was exploring whether previous crops influenced microbial community functioning in subsequent cropping years; whether differences in the amount and quality of residue/stubble impacted microbial communities responsible for transforming organic and mineral N to plant-available N; and whether agronomic practices such as tillage and depth of fertiliser placement could be strategically used to manipulate N-cycling microbial communities... Caption: Soil microbiologist Lori Phillips says current research is aimed at determining the make-up of microbial communities in the soil, their role in nutrient cycling and how farming practices influence microbial activity...

Most farmers in the region would prefer to then apply their nitrogen to soils with a full moisture profile to maximise the benefit to the crop of their fertiliser investment... The decision will have to be made sooner for some than others - many growers ordered urea six months ago when prices were low; they now need to decide whether to accept those orders and apply their usual rate to their full farming area, or let those early orders go and take more expensive product when it does decide to rain... The upside of applying nitrogen in dry conditions is that it will remain in the soil until activated by rainfall and infiltrate down the profile, whereas applying fertiliser N to a full moisture profile can lead to high gaseous losses through ammonia volatilisation and denitrification in the event of further heavy rainfall and waterlogging as it has nowhere to go...

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...

Greg's analysis for the years 2006-12 showed top businesses in the eastern wheatbelt generated $42.56/hectare more than the average of those in the Planfarm Bankwest Benchmarks for the region... Greg Kirk will be presenting and discussing the results from the GRDC project 'How to Farm Profitably in the Eastern Wheatbelt of WA' at the Agribusiness Crop Updates in Perth on Tuesday February 25... Region West, North, South < Keep browsing 0 Responses to Practices for profits in the eastern wheatbelt..

Dr Mark Peoples (pictured) says that both fertilisers and legumes have a role to play in supplying N... "The trials demonstrated that, as expected, rotations that resulted in highest returns of fixed to the soil were brown manured crops, and grazed or hay-cut legume pastures , since large amounts of N are removed from pulse crops in the harvested grain," Dr Peoples said... Legumes also have other benefits, including increasing soil organic fertility, weed and disease management, and the development of beneficial soil biology growers should consider both options as both have a place within a farming system...
