The Quirk Farm Story
In 1987 a major fish kill occurred in the Tweed River close to Robert Quirk’s sugar cane farm. Initially the cane farmers in the region were blamed for the fish kill due to their high usage of fertilisers, insecticides and pesticides which were said to have leached into the river and killed the fish.
Robert Quirk did not accept this explanation for the fish kill due to anecdotal evidence of fish kills occurring in the region prior to the presence of cane farming. Working in conjunction with researchers and scientists Robert Quirk discovered that the underlying cause of the fish kill was acid sulphates in the soil beneath the cane fields. When the acid sulphates mobilised and moved into the waterways, fish kills occurred.

Robert Quirk implemented innovations such as laser levelling his cane fields and mounding the cane rows to ensure that water drained correctly off his property and didn’t mobilise the acid sulphates in the soil.
During this time Robert Quirk became aware of the danger of climate change, this caused Robert Quirk to alter his management practices in an attempt to build carbon in his soil and reduce inputs. Robert Quirk reduced the amount of fertilisers, insecticides and pesticides used on the property as well as leaving the cane trash to lie on the field post-harvest. Robert Quirk also introduced other innovations such as an automatic pumping system to remove flood water from the cane fields and a bed renovator machine to prepare the cane fields.
Robert Quirk found that through his innovations soil organic carbon levels increased from 1% in the 1960’s to currently 8.8% on different points of the property. The pH of the property also increased from 1.8 in the 1980’s to currently stand at 5.6. Robert Quirk’s innovations have greatly improved the health of his soil whilst managing to control the threat of the acid sulphates underneath his cane fields.

The practices Robert Quirk has implemented on his property have led the way for sugar cane farming around the world.
In 1987 Robert Quirk set out on a path to improve the ecological health of his property and the nearby waterways.
Robert Quirk has significantly reduced the cost of his inputs whilst maintaining good production levels.
