petro derived chemical ferts are actually as organic as you can get.
COPIED! (livescience)
''dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand. Over time, more sediment piles on top and the resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen.
Left alone, the kerogen molecules eventually crack, breaking up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms. Depending on how liquid or gaseous this mixture is, it will turn into either petroleum or natural gas.
So how long does this process take?
Scientists aren't really sure, but they figure it's probably on the order of hundreds of thousands of years. ''
