nitrogen issues

Open Archive Day

The Haber process is the place where textbook chemistry meets global food security and lots of environmental concerns, so it's a very satisfying topic for me to write about, as I can expand from molecules to global issues, and even recycle some of the things I learned during my studies. I've recently done a C&I feature on modern attempts to improve on Haber and dreams of an ammonia economy, and also reviewed more Haber biographies than I care to remember (eg this one), but the big nitrogen feature taking the whole environmental and food security problems was this one in 2012, which is in the open archives:

Until the advent of the Haber–Bosch synthesis 100 years ago, guano was the main source of nitrogen fertiliser, ensuring that reactive nitrogen ran in closed natural cycles. (Photo: Joan Thirlaway.)
