I agree with you that this seems to be a load of BS, for a few reasons:

a) I cannot find a scientific paper on this, or any signs of proper scientific research (as a science undergraduate, I am being trained to need a proper scientific report to believe in a hypothesis)

b) This quote from Dr. Jill Clapperton on the 'official' website: "It works, and its my job to find out how it works. We will be able to tell you exactly what's happening in the soil in 3-5 years." http://www.bioagtive.com/?s=1&p=413&op=153 (suspicious much?)

c) The most important component of fertiliser is Nitrogen in the form of ammonium (NH4+) and Nitrate (NO3-). Diesel does not release usable amounts of nitrogen in a form that can be utilised by the plant or the nitrogen-fixing bacteria in the soil.

d) Plants also require Potassium, Phosphorous, Calcium, Magnesium and Sulfur. Diesel does not contain all of these elements. CO2 cannot magically turn into all this!

e) I never trust something that believes in carbon emissions trading schemes http://www.bioagtive.com/?s=1&p=143

No, it's an attempt to get money from the Carbon Emissions Trading Scheme! http://www.bioagtive.com/?s=1&p=143 [bioagtive.com] I agree with you that this seems to be a load of BS, as: a) I cannot find a scientific paper on this, or any signs of proper scientific research b) This quote from Dr. Jill Clapperton on the 'official' website: "It works, and its my job to find out how it works.

Some people actually paid to come to this country. Australia is full of land, something the U.K. did not have very much of.

Politically - Australia is full of people who do not understand the internet (for example - that internet filtering thing) and will not vote for a government which understands the internet, and respects our civil liberties.
