  abstract = {{C}onventional, intensively managed coffee plantations are currently facing environmental challenges. {T}he use of shade trees and the organic management of coffee crops are welcome alternatives, aiming to reduce synthetic inputs and restore soil biological balance. {H}owever, little is known about the impacts of the different types of shade tree species on soil functioning and fauna. {I}n this paper, we assess soil nutrient availability and food web structure on a 17-year old experimental coffee plantation in {T}urrialba in {C}osta {R}ica. {T}hree shade types (unshaded coffee, shaded with {T}erminalia amazonia, and shaded with {E}rythrina poepiggiana) combined with two management practices (organic and conventional) were evaluated. {T}otal {C} and {N}, inorganic {N} and {O}lsen {P} content, soil p{H}, global soil fertility, and nematode and microarthropod communities were measured in the top 10 cm soil layer, with the objective of determining how shade tree species impact the soil food web and soil {C}, {N} and {P} cycling under different types of management. {W}e noted a decrease in soil inorganic {N} content and nematode density under conventional management (respectively -47% and -91% compared to organic management), which suggested an important biological imbalance, possibly caused by the lack of organic amendment. {U}nder conventional management, soil nutrient availability and fauna densities were higher under shade, regardless of the shade tree species. {U}nder organic management, only soils under {E}. poeppigiana, a heavily pruned. {N}-2 -fixing species, had increased nutrient availability and fauna density, while {T} amazonia shade had a null or negative impact. {T}he effects of coffee management and shade type on soil nutrient availability were mirrored by changes in soil food web structure. {H}igher fertility was recorded in soil with balanced food webs. {T}hese results emphasize the importance of the choice of shade tree species for soil functions in low input systems, more so than in fertilized systems.},
