New research: synthetic nitrogen destroys soil carbon, undermines soil health
Tom Philpott, Grist

For all of its ecological baggage, synthetic nitrogen does one good deed for the environment: it helps build carbon in soil. At least, that’s what scientists have assumed for decades. If that were true, it would count as a major environmental benefit of synthetic N use...Well, that logic has come under fierce challenge from a team of University of Illinois researchers led by professors Richard Mulvaney, Saeed Khan, and Tim Ellsworth.
