We show qualitative classifications of the different study sites that coarsely approximate the range of Coffea arabica growing conditions, country and coordinates, elevation (m), mean annual precipitation (MAP, mm)/mean annual temperature (MAT, °C), C. arabica variety, shade tree (Erythrina poeppigiana or Inga laurina) and density (stems ha-1), and soil metrics at the management treatment (full sun or agroforestry) level [soil N (%), soil C (%), soil P (mg kg-1), soil pH and soil moisture (%); n = 16)].
