A stock take of knowledge on soil amelioration tools

Yield improvement was the key benefit from soil amelioration reported in the research literature and farmer interviews.
There was a divergence in the research findings and in-paddock experience of farmers for crop vigour, ability to increase season length and crop establishment.
The key knowledge gaps identified were the effect of soil amelioration tools on crop diseases, in-paddock nutrition and herbicide application and variability in tool cost.
The findings support grower understanding and adoption of soil amelioration tools, identify knowledge gaps and provide recommendations for future research.
