nitrogen and climate change, page-6

I've seen a few discussions on nitrogen fertilizers and some of the risks like run-off, N impact with more CO2 and plant growth etc. This one is talking about the need to look at the whole cycle and the different parts of the cycle and how we are changing it.

Looks interesting. The chemistry of the cycles are pretty well known but the impact we are having overall through fertilizers etc might not be as well understood.
