The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.
Take home messages from the paper include:
- A pasture phase rebuilds organic carbon (C) and soil nitrogen (N) reserves.
- A pasture phase provides opportunities to reduce the weed seed bank prior to cropping.
- To achieve these benefits, the pasture must be dense, productive and persistent.
- Soil test – ensure that all nutrition issues are addressed at establishment and across the entire pasture phase, in particular phosphorus (P), sulphur (S) and molybdenum (Mo).
- pH stratification and subsoil acidity have the potential to severely compromise pasture production.
- Pasture legumes must have effective rhizobia nodules to fix N effectively.
- Winter cleaning within the pasture phase is a highly effective practice for weed control and lasting crop rotational benefits in terms of N and cereal root diseases.
- Match pasture type to desired outcome and utilisation potential.
