Aims

To investigate the composition of the free living nematode communities in Australian grain-growing soils; determine whether the community responds to different organic matter inputs and to various tillage and stubble management regimes; and decide whether nematodes are a useful indicator of soil health.

Key messages
  • Organic amendments improved ‘soil health’ in terms of free living nematode community structure.
  • The Tilled + Organic Matter treatment had a more well balanced soil microbial system than other treatments.
  • Numbers of omnivorous and predatory nematodes are quite low in comparison to other cropped soils around Australia, thus room for improvement.
  • Soils have improved, as the number of omnivorous nematodes in 2013 significantly increased in organic amended treatments, in comparison to 2011.
