  abstract = {{C}rops in shifting cultivation fields often suffer from severe weed infestation when long fallow periods are replaced by short fallow periods. {T}he soil seedbank as a source of weed infestation was studied in four fields that differed in their last fallow duration. {T}he effect of burning was analysed by comparing adjacent pre-burn and post-burn samples (two sites). {S}urface vegetation was monitored from burning to harvest in the plots from which soil samples were taken to determine the fraction of the seedbank germinating (three sites). {S}eedbank size (1700-4000seedlingsm(-2)) varied depending on a single species, {M}imosa diplotricha. {B}urning reduced emergence of most species, but stimulated emergence in others. {D}ensities in the seedbank were not correlated with above-ground abundances in the field, except for some species. {M}ost species emerging after 50days from the soil samples (40% of seedlings) were absent from the field after 190days. {W}hilst the data from this study are derived from only four fields, the weed problems after short-term fallowing appeared to be due to a larger fraction of the seedbank emerging, possibly due to shallow burial, and to a floristic shift towards adaption to burning, rather than the size of the seedbank per se.},
