  abstract = {{S}equestration of atmospheric carbon ({C}) into soils is a strategy to compensate for anthropogenic emissions of carbon dioxide. {T}he response of {SOC}s to crop types is yet to be determined under different environments. {T}he objectives of this study were to elucidate the impact of crop type on the allocation of atmospheric {C} to shoots and roots, and ultimately to the soils and to determine its association with soil carbon stocks. {T}hree hundred and eighty-nine field trials were compared to determine allocation of biomass and {C} in plants and {SOC}s under fields of different crop types. {G}rasses had the highest plant biomass production (19.80 +/- 1.16 {M}g ha(-1) yr(-1)), followed by cereals (9.44 +/- 0.45 {M}g ha(-1) yr(-1)), fibre (7.90 +/- 1.00 {M}g ha(-1) yr(-1)), legumes (3.29 +/- 0.63 {M}g ha(-1) yr(-1)), and oil crops (3.05 +/- 1.16 {M}g ha(-1) yr(-1)) showing significant differences (p < 0.05). {M}aize (6.3 +/- 0.34 {M}g {C} ha(-1) yr(-1)) had the highest plant {C} amongst summer crops, while wheat (2.2 +/- 0.35 {M}g {C} ha(-1) yr(-1)) had the highest plant {C} amongst winter crops. {I}n all the studies, crops allocated more {C} to their shoots than roots yielding root {C}: shoot {C} ({R}c/{S}c) ratios below magnitude. {T}he greatest {C} allocation to roots was in grasses ({R}c/{S}c = 1.19 +/- 0.08), followed by cereals (0.95 +/- 0.03), legumes (0.86 +/- 0.04), oil crops (0.85 +/- 0.08), and fibre crops (0.50 +/- 0.07). {T}here was evidence that high plant {C} stocks were found in crops grown under carbon rich clayey soils of tropical humid areas. {N}atural grasses and cereals should be promoted as they appeared to yield greater potential for atmospheric carbon sequestration in plants and soils. {O}verall, the study evaluated the relative potential of the main crop types to sequester atmospheric {C} useful in screening of crop types for carbon efficiency and for development of plant {C} models.},
