  abstract = {{B}razil is the world's largest sugarcane producer, so changes in sugarcane management in {B}razil can affect the environment to a great extent. {D}uring almost one century, studies were carried out in cropping systems involving pre-harvest burning of aerial sugarcane residues. {N}owadays the green trash management of sugarcane residues has become a common practice, although the effects are still poorly documented. {T}he objective of this work was to compare topsoil carbon and nitrogen stocks, aggregation and bulk density in {B}razilian sugarcane plantations where aerial residues were either burned ({C}q) or left on the soil surface ({S}q) after harvest. {T}he study was carried out in three plantations, one on a clayey soil ({L}atossolo {V}ermelho, {LV}df i.e. {T}ypic {H}apludox) and two on sandy soils ({A}rgissolo {V}ermelho-{A}marelo, {PVA}d, i.e. {T}ypic {H}opludult, and {N}eossolo {Q}uartzarenico, {RQ}o, i.e. {Q}uartzpsamment). {O}n each plantation, the experimental design included six replications per treatment. {A}fter three crops, the accumulated aerial residue biomass in {S}q treatment amounted to 40 t ha(-1) of {DM} from which 4.5 and 3.6 t ha(-1) of {DM} (i.e. 11 and 9 %) were still present at the soil surface in {LV}df and {RQ}o, respectively. {T}his represented 1.60 and 1.35 t ha(-1) of {C} and 0.022 and 0.021 t ha(-1) of {N}, respectively. {A}s a result, soil carbon at a 0-20 cm depth increased by 6.3 and 4.7 t ha(-1) in {LV}df and {RQ}o, respectively. {O}ver the three-year period, the rate of carbon sequestration in the litter and topsoil in the {S}q treatment was 2.63 and 2.02 t ha(-1) yr(-1) in {LV}df and {RQ}o, respectively. {T}opsoil content of stable macroaggregates was also higher with {S}q than with {C}q: 814 vs. 693 g kg(-1) in {LV}df and 516 vs, 420 g kg(-1) in {RQ}o, respectively. {O}n the other hand, {S}q caused topsoil compaction ({PVA}d and {RQ}o) due to the mechanized harvest system. {I}n the {B}razilian soils under study, green trash management of sugarcane residues improved the topsoil properties and promoted carbon and nitrogen sequestration in the litter and topsoil.},
