    Examining the complementarity in belowground water use between different varieties and ages of Arabica coffee plants and dominant shade tree species in an organic agroecosystem by Lyssette Elena Muñoz-Villers, Friso Holwerda, M. Susana Alvarado-Barrientos, Josie Geris, Todd E. Dawson

    Published 2025-02-01
    “…The absence or potential presence of competition for soil water in the studied coffee plants was investigated using a combination of stomatal conductance measurements and modeling, supported by leaf and root hydraulic trait data. Results show that the observed relative and absolute plant water uptake patterns provide evidence of vertical complementarity in belowground water use between coffee and shade trees during the dry season. …”
