The latest in evidence-based scientific data on cropping soils, carbon sequestration and farming systems will be presented at the upcoming Grains Research and Development Corporation (GRDC) Update being held in Goondiwindi... World renowned expert in soil systems, Professor Iain Young from the University of New England will explore soil, plant and microbe interactions in cropping soils and provide an international perspective that advisers and growers can't afford to miss... "The Update is a chance for growers and advisers to tap into the latest research, liaise with our expert local and international guest speakers and become better informed on ways to boost productivity on farm in a more sustainable manner."..

Soil testing the key to fertiliser savings.. According to the Crop Nutrition Fact Sheet published recently by the Grains Research and Development Corporation (GRDC), results from more than 100,000 recent soil tests in the south-west of WA showed that most growers are operating at or above the soil P levels required... If the tests show that soil P status is sufficient, there may be an opportunity for growers to save money on P fertiliser by cutting back to a maintenance rate...

Soil monitoring important following fire.. Soils affected by fire can have their microbial buffer against diseases weakened... While some plant pathogens may be reduced following extreme fire events such as the Pinery fire in South Australia's lower north region last year, growers affected by fire are being urged to monitor nutrient levels and soilborne disease pathogens in the lead-up to and during the 2016 growing season...

Subsoil reserves of mineral nutrients such as P have been run down over recent decades, with practices such as direct drill cropping accelerating the loss... The GRDC fact sheet recommends testing subsoil (10 to 30 centimetres) P levels, using both the Colwell-P and BSES-P tests across the farm, as the key to making an informed decision about fertiliser strategy... Soil testing provides an understanding of your fertility profile and is a vital step in making informed fertiliser decisions...

"Currently only a small proportion of growers test soils to this depth, but it is necessary to provide the information they need to help them decide whether to apply lime before or after mouldboard ploughing or spading," he said... "After mouldboard ploughing or spading, but before seeding, growers should ideally go back and sample soils a second time to a depth of 20cm to help them assess soil nutrition requirements - particularly for phosphorus and potassium... "If growers do not have enough time to do nutrient testing between mouldboard ploughing or spading, and seeding, they need to make sure they test for nutrient levels, as well as pH, when soil testing the first time."..

After decades of consistent phosphorus (P) fertiliser application, many Western Australian soils now have adequate P status, presenting an opportunity for farmers to save on input costs... Testing subsoil (10 to 30 centimetres) P levels using both the Colwell-P and BSES-P tests across the farm is the key to making an informed decision about fertiliser applications rates...

Recent Grains Research and Development Corporation-funded (GRDC) research in the northern region shows native remnant vegetation measures around three per cent soil organic carbon (OC) in the top 10 centimetres of the soil... Soil that has been cropped long term is about 1% OC, which indicates long term cropping has decreased OC by 2%.This is a massive drop in the real value of land... A 2% decrease equates to at least 20 tonnes per hectare of OC lost from the soil (assuming bulk density of only 1.0)...
