As an engineer, I'm forced to ask, "How does it work?"
I'm professionally cautious about claims that advertise large savings for small investment. Especially 'Green' claims in news articles. For all I know this guy spent $20,000 on a muffler bearing and is claiming it will save the earth...
CO2 in the soil and Nitrous Oxide in the soil may entice the soil bacteria to produce more nitrogen.
Having the academic community investigate would be a better use of the tax money that goes to their welfare than studying which beer cockroaches prefer.
Many years ago in Australia the academics could not figure out why the crops would not grow with all the witches brew they dumped on the ground. Then a farmer noticed the grass grew best next to the chain link fence. The soil was deficient in Zinc, they added zinc and the crops grew.
The guy in South Africa may have a shortage of carbon in the soil.
