What amazes me is the idea that petrol engines are safer than diesels...
If you cool the exhaust gas of a diesel and then inject it into the soil, the grass will still grow and the plants will have a soil structure that has gained carbon, nitrogen, co2 and a few elements in the process... If this is done in an air seeder, it will inoculate the seed and shorten the time it takes to germinate... It will not replace fertilizer as it is a gas... Oh and it will stop Bracken from growing, it actually stabilizes the soil PH...
Do the same with petrol and everything dies...
But you can see the pollution of diesels so it must be bad, you cant see petrol exhaust fumes so it is safe[tonguewink]
