2. I don't claim to be an expert on any of this.

I leave that to the experts

What I've read so far with regards to terra preta is that it is a viable form of carbon capture, even more-so than planting trees in an equal amount of land.

I agree about bamboo being practically a "universal" plant in what it can be used for. The same is true for hemp, if we can ever push the DEA aside and allow it to be farmed. Both plants are also good at helping to stop soil erosion due to their broad root systems.

I haven't read about manufactured fertilizers leaving a residue in food, only that runoff high in fertilizer is a major concern for water bodies, due to algae bloom, and subsequent dead zones.
