Preliminary results have shown that a maize-coffee cropping system acts like a huge atmospheric carbon sink, capturing up to 60 times more carbon than a coffee-bean system during one cycle of the associated temporary bean crop. In addition, maize creates a more adequate microclimate for coffee’s growth and development because it reduces air temperature, helps to maintain soil moisture and decreases daytime-nighttime soil temperature fluctuations. This has a buffer effect that benefits soil biochemical processes and improves crop productivity.
