  abstract = {{S}haping and pollarding of dimorphic ash tree ({F}raxinus dimorpha) are two traditional practices used by the local inhabitants in agropastoral parklands of the {M}oroccan {H}igh {A}tlas to secure their production systems and increase tree production and strength. {T}his study focused on assessing the impact of these practices on soil quality. {A}biotic parameters and mycorrhizal attributes of the samples of four soil types related to different ash tree morphotypes were assessed and compared. {R}hizospheric soils ({R}s) of three {F}. dimorpha morphotypes were sampled: trees regularly pollarded and shaped for stem anastomosis ({A}n), regularly pollarded multistemmed trees ({N}a), and multistemmed trees belonging to a public forest under national forestry service management and sporadically illegally pollarded ({F}o). {T}he fourth soil was a non-{R}s found in bare soils, which represented the control ({N}r). {R}esults showed a sizable difference between {A}n soil properties and the other soil types ones, with significantly higher phosphorus (x6), nitrogen (x5), and carbon (x2) levels and higher mycorrhizal (x6) status than {N}r soil, and showed 37% more mycorrhization intensity than {F}o. {N}a showed intermediary levels between {A}n and {F}o. {F}o had x2 {P}, x3 {T}otal {K}jeldahl {N}itrogen ({TKN}), 58% more {T}otal {O}rganic {C}arbon ({TOC}) content, and twice the spore density compared with {N}r. {I}t is concluded that shaping and pollarding have a positive impact on the soil characteristics of the studied species and could make a useful contribution to sound agroforest management schemes.},
