Description Different multipurpose tree species integrated into agroforestry may exhibit variable effects on soil characteristics, which not only depend on planted tree species but also on tree management practices being adopted. In the present study, the effect of different tree management practices on soil organic carbon, dehydrogenase activity, microbial biomass carbon and potentially mineralizable nitrogen was assessed in three well-established agroforestry models viz. model 1: crown pruning management [three levels: 0 (unpruned), 50 and 75%] in Albizia procera, model 2: tree density management (three levels: 200, 400 and 800 trees ha−1) in Hardwickia binata, and model 3: in situ soil moisture conservation (SMC) measures [four levels: normal planting (control), stone mulch, deep basin and deep basin + deep ploughing] in Emblica officinalis-based agroforestry. The aim was to determine (1) whether tree management practices have any effect on soil biological properties, and (2) what levels of these management practices are desirable in selected agroforestry systems. We hypothesized that these practices will improve soil in terms of biological properties, with moderate levels being more beneficial. For the purpose, soil samples were collected from two sampling locations [rhizosphere (> 1.5 m from tree base) and the non-rhizosphere zone (outside the tree canopy i.e.
