Plants that absorb carbon monooxide and other drainage gases
If you were trying to use plants to mediate this you would need to approach it at some other point. No plant in the hole or around it will "absorb" gases to reduce the ppm below detectable ...

I need nitrogen-poor soil. Where can I buy some (US)?
I see two possibilities:
You get poor soil
You transform your soil
You can walk around your place, and you will see some places with poor soil. This probably is also poor on nitrogen. Try a dry, ...

Scorpion Pepper growth
By the look of it, I would suppose that the plant isn't getting enough calcium, even if there's enough in the soil. That is, if the same leaves initially grew like that (if not, I'd suspect a pest or ...

Does nitrogen-rich material become carbon-rich after drying?
You are missing the fact that the ratio of carbon to nitrogen in organic material is nowhere near a 50/50 split. The difference between "nitrogen rich" and "nitrogen poor" is more ...

What is the carbon content of tree seeds and would they be suitable to balance nitrogen rich compost?
The seed itself is probably not a great thing to add to compost in large quantities. Seeds have protective coatings on them that will take a very long time to break down.
However, everything around ...
