Here is the audio from a video that Tom shot on a trip to Colombia. "This is a long form talk with Leo and Jenni Henao at the farm in Urrao Antioquia, Colombia. Maybe of interest to farmers and gardeners more than coffee. Leo and I are friends and I'm trying to get him to laugh in this video. But the topic and his use of micro-organisms in composting is very interesting!" -Tom CLICK HERE to watch the video.
