The effects of genetic modification on the decomposition process of corn residues were investigated under field conditions. Using litter-bag method the decomposition of different residues - leaf and root tissues of transgenic Bt (DK440BTY)and isogenic non-Bt corn plants (DK440), and different soil types - where previously Bt corn or isogenic corn had been grown, was compared. Significant differences were found in the decomposition in some cases - in Bt soil, between plants regarding the isogenic leaf residues, but not in the decomposition of the root residues. The potential reasons are discussed in the study.
