Beef production using feedlots is growing fastest in developing countries. Research in the US is ongoing on how to fix the CH4 and N2O emissions. Sounds like an opportunity for biochar.
From The New York Times:
Belching Cows and Endless Feedlots: Fixing Cattle’s Climate Issues
The United States is home to 95 million cattle, and changing what they eat could have a significant effect on emissions of greenhouse gases like methane that are warming the world.

It's a nice opportunity in the field of biochar. We found in research that sewage sludge biochar producing in pyrolysis temperature 320 ℃ is the highest container of available phosphorus. But the C-N ratio was higher in high-temperature biochar (520 and 620 ℃).
