Effects of fumigation and soil amendments on nematode-feeding groups in cereal growing soils locations
Aims

To quantify the effects of nematode feeding groups in Western Australian soils on crop performance.

Key messages
  • The soil treatments investigated at these sites are considered to be ineffective for broad acre farming.
  • Changes to nematode composition and microbial biomass were small and did not result in plant biomass production.
  • Inprovements in the effectiveness of the soil treatments may occur when applied as seed dressings.
