A wheat farmer in Australia has eliminated adding fertilizer to his crop by the simple process of injecting the cooled diesel exhaust of his modified tractor into the ground when the wheat is being sown. In doing so he eliminates releasingcarbon into the atmosphere and at the same time saves himself up to $500,000 (AUD) that would have been required to fertilize his 3,900 hectares in the traditional way.
