Fertilizers are made from Amonia which in turn is made using the Haber-Bosch process which requires fossil fuels to provide the necessary energy and as reactants

That's exactly what I said! Fertilizer is not made from oil. The factory is powered by oil. Just like your home where you garden is powered by oil.

Natural Gas - which is not renewable - is a reactant and Oil is still involved indirectly as a means to generate the power needed for the process. This can be replaced but is more expensive.

That said, it's unclear to me if Oil is somehow used at the chemical plant to generate said energy (for example, to reach the necessary temperatures) or if it's even more indirect than that and it's just fuelling Power Generation plants which in turn provide electricity used in the heating, pressure generation and subsequent cooling for that process, in which case it could be replaced by something renewable.

If it is the latter case I have to agree that it's not quite as bad in the renewable sense as I thought.

Good news.

Guess my info on that was quite outdated.
