  abstract = {{D}eep soil carbon (>30 cm) is the primary pool of soil organic carbon ({SOC}). {H}owever, deep {SOC} is often not included in carbon inventories or management strategies, especially in {N}orth-{A}frica. {T}he objective of the study was to determine the distribution and the main factors governing {SOC} storage along a representative toposequence in {N}orth-{E}astern {A}lgeria. {T}he soil organic matter ({SOM}) was characterized by {SOC} content, carbon stocks, particle size distribution and mineralization potential. {T}he amount and the dynamics of the deep {SOC} depended on the topographical position. {I}n the mountain soils, most of the {SOC} stock (100 t {C} ha1) was in the topsoil (0e30 cm) and associated with the >50 mm fractions (plant materials) whereas in the piedmont and alluvial plain soils, most of the {SOC} stock (168 t {C} ha1) was accumulated in subsoil (30e100 cm) and associated with the <20 mm fractions (mineral fractions). {T}he {SOC} in the subsoil contributed to {SOC} potential of mineralization and should not be underestimated, especially in the alluvial cultivated plains. {T}his carbon should be considered as an important component in agro-ecological agriculture but it is also a potential source of {CO}2.},
