Zanmi Kafe interns Ben McKenzie and Pierre Wakenfort practice using the Licor 6400 to measure photosynthesis in a farmer’s field of corn and beans.  These sun-loving annual plants capture carbon at a rate of 20 umol/m2/sec in full sun!  The sophisticated 40-lb instrument was transported on the back of a donkey during the 2 hour mountainous hike to Bois Jolie.  Our ultimate goal is to compare rates of photosynthesis among year-old coffee seedlings to determine the impact of varying light levels and rust infection on the growth of this understory tree crop.
