%X the influence of 31 years of stubble burning on the carbon storage as well of chemical composition of soil organic matter (som) was studied in agricultural soil of a long-term field experiment. additionally, the potential of black carbon (bc) produced by burning of harvesting residues, to be lost by horizontal as well as vertical transport was quantified during a rainfall simulation experiment. our results show that 31 years of stubbie burning as a regular agricultural practice did not change carbon storage or the chemical composition of som. this is most likely due to a small quantitative input of highly stable aromatic carbon into the soil. a significant portion of bc deposited on the soil surface by the fire may have been exported from the site as shown during the rainfall simulation experiment.
