Author/s: Soil Microbiology Section Published: 2010.. Root-lesion nematodes can take half your yield... Break up the soil by hand in a bucket so that all pieces are less than 1 cm in size keeping the six lots separate (Failing to do so may incur a processing fee of $78.41)...

Growers praised for efforts to preserve healthy soils.. On the eve of World Soil Day (December 5), Grains Research and Development Corporation (GRDC) Managing Director John Harvey says it is timely to acknowledge the grains industry's efforts in ensuring the long-term fertility of soils, necessary for essential food production... Scientists involved in the Soil Biology Initiative agree that the program is making considerable progress in understanding the composition of the living fraction of soils which support crop production, and how growers can best manage soils to maximise nutrient capture and defend against crop disease...

Growers urged to soil test for nematodes prior to winter plant.. All major winter crops, wheat, barley and chickpeas, are susceptible to the root-lesion nematode species P. thornei and encourage the proliferation of nematode populations... Department of Agriculture, Fisheries and Forestry (DAFF) soil microbiologist Dr Kirsty Owen told growers and advisors at the recent Grains Research and Development Corporation (GRDC) Grains Research Update at Goondiwindi that a pre-sowing assessment of soil nematode populations was critical to minimise the risk of yield loss through crop and variety selection...

"It is important that we take what we now know out to the farming community so growers can gain a better understanding of how soils respond to management practices.".. The GRDC has established the Soil Biology Initiative to explore what is seen as the "last frontier" for the grains industry, "The arrival and rapid development of new technologies now means we are finally in a position to delve deep into the soil biological communities and see not only who is there but what they are doing, not only as individual species but as highly interactive communities," Assoc Prof Mele said... Knowledge and understanding generated through the Soil Biology Initiative's extensive suite of research projects is expected to lead to recommendations on how growers can best manage soils to maximise nutrient capture and defend against disease, resulting in less reliance on chemical controls and reduced inputs...

This project aims to develop DNA tests to quantify Free Living Nematode (FLN) groups in soil, which will be useful indicators of soil quality... Nematodes are useful biological indicators of soil health because they: occur in all soils; are readily extracted and identified; have a wide range of food sources; are ecologically and taxonomically diverse; and respond to changes in food sources, as well as soil physical and chemical properties Indices derived from nematode community analyses can be used to provide information about a soil ecosystem with respect to nutrient status, presence of pollutants, disturbance and disease suppression... The project will provide information on free-living nematode communities in key Australian cropping soils, identify groups which will be useful to assess soil biological health and link analysis to soil quality monitoring...

Living organisms play a vital role in soil management and should be encouraged.. Bacteria, fungi, nematodes and worms are just a handful of the soil organisms that, when managed correctly, contribute to healthier crops, a leading Canadian rhizosphere ecologist has explained to WA growers... [Photo (left) by Brendon Cant: Canadian rhizosphere ecologist Dr Jill Clapperton.] "Soil microbial life is necessary to improve soil structure, soil softness or tilth and productivity, and plants can better use nutrients from biological processes than chemical fertilisers," Dr Clapperton said...

Over recent years soil water has become an increasingly important component of crop management in Australia?s broadacre cropping systems... The development of the Soil Water Express, provides users with the potential to undertake a rapid, but less accurate, prediction of PAWC based on locally derived soil data and functions developed from information contained in the APSoil database... Whilst in-situ electronic monitoring devices including NIR and capacitance probes provide an adequate picture of soil water in rigid soils, they were found to be inappropriate for shrink/swell soils where cracking and soil movement interfere with accurate recording...

Little could the couple have realised that it would be 30 years before the trial program would finally wind up, and by then be cemented into history as one of the most remarkable sources of knowledge on Australian dryland cropping... The new concept of direct-drilling crops using a non-residual herbicide (Sprayseed ) instead of ploughing was measured against conventional cultivation... "And if we take outcomes from the Mallee Sustainable Farming project alone, we estimate that the benefits of modifying and adopting the research findings from the Avon site amount to about $500 million each year in increased grain production and reduced wind erosion," Dr Rovira said...
