Ben McKenzie and Pierre Wakenfort assessing photosynthesis rates, Bois Jolie, Haiti. May, 2015.
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.
