It's hard to talk about farming without talking about global warming which is political.
Excessive use of nitrogen-based fertilisers in agriculture is contributing to nitrous oxide emissions.
Leftover nitrogen that hasn’t been absorbed by plants, reacts with the soil to produce this dangerous greenhouse gas.
Agriculture accounts for 80% of human-caused nitrous oxide emissions globally and for 8-14% of all greenhouse gasses.
Helping farmers to apply more precise quantities of nitrogen fertiliser will thus be able to help combat climate change.

An investment group wants to make a fertilizer in Terre Haute, capture the CO2 and inject it under ground.
That is creating a big stir. Don't put CO2 in my drinking water.
