A match made in canola heaven.. In the first series we look at how growers and researchers teamed up to turn canola into one of the mainstays of today's cropping system... "Over a decade of experiments, our team demonstrated the rotational benefit of canola, and growers saw that while it could be expensive and tricky to grow, it was profitable if you took a two-year view," he says...

"Over a decade of experiments, our team demonstrated the rotational benefit of canola, and growers saw that while it could be expensive and tricky to grow, it was profitable if you took a two-year view," he says... To help growers manage risk in canola in dry years, Dr Kirkegaard developed a simple yield calculator based on rainfall to determine a particular crop's yield potential so inputs were not wasted...

"Farmers have embraced conservation agriculture because it makes good sense to protect the soil, conserve water and save time, labour and fuel," he said... Factors that detracted from the benefits of conservation agriculture in Australia included weeds, root disease and inhibitory soil organisms that could slow early crop growth and reduce yields... Dr Kirkegaard said soil disturbance could be required to incorporate these inorganic nutrients below the soil surface where they can stabilise carbon, allowing it to build up in the soil...
