Brown Manures, Cover Crops and Long Fallows – How Decreasing Crop Intensity Can Reduce Costs and Risk, While Increasing Profit – Case Study
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.
- Reducing crop intensity can reduce variable costs and risk, while increasing profit
- Use a long-term, systems approach when considering a brown manure, cover crop or long fallow. Many of the benefits from this appear two to three years later
- ‘Problem’ paddocks with weed or soil fertility issues are the best place to start, as these are often unprofitable when cropped, so opportunity cost is minimal.
