Plasmas are finding a growing number of applications in food production and agriculture. In this interview, Dave Graves of the University of California, Berkeley talks about the physics and chemistry of non-thermal (or cold) plasmas and explains how these plasmas could improve food and agriculture.
He also talks about a special issue of Journal of Physics D that focuses on plasmas in agriculture and the food cycle.
This is a longer version of the interview with Graves that appeared in the 26 March episode of the Physics World Weekly podcast.
