free living nematode

Catalogue: GRDC Research Summaries
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...

Data presented showed that farm practices that have a positive impact on soil biology include no-till, effective crop sequencing (rotations), lime applications and building up soil carbon... Soil microbiologist Dr Lori Phillips of the Victorian Department of Environment and Primary Industries (DEPI) says there are direct links between the microbes that release nitrogen from crop residues and soil sources, and the microbes that convert fertiliser nitrogen to crop-available nitrogen... In related research, the University of Western Australia's Professor Dan Murphy said his work had shown that organic molecules released from plant roots had more influence on the microbes that can retain (immobilise) nitrogen than soil organic carbon levels...
