Occasional strategic tillage (ST) in Australia has been suggested to help control herbicide resistant weeds. This study looked at the impact of ST two systems -- no-tillage (NT) versus conventional tillage (CT) that were applied on a Vertosol soil for 49 years on various biological properties. There was no significant effect of ST on the measured biological attributes. However, total enzymatic activity for treatments under CTSR and CTSR-ST were significantly higher compared with NTSR-ST. Differences may be attributed to a significant increase in bulk density for CTSR treatment and an increment in bulk density on CTSR-ST plots. The lack of changes may be attributed to a high resistance and/or resilience of soil microbial communities after 15 weeks of tillage. More studies on the long-term effect of ST are required to assess the impact on soil biological properties.
