More from this show

Fertilizer drives modern agriculture to feed the world. It turns natural gas, nitrogen from the atmosphere and mined minerals into plant nutrients, which end up on our plates to nourish our bodies but with large energy and greenhouse gas footprints. We’ll discuss benefits, challenges and potential solutions with Chrystel Monthean from Yara and Dr. Jason Haegele from ICL Group.
