Interpretive Summary:

Technical Abstract: Bt corn hybrids produce insecticidal proteins that are derived from a bacterium, Bacillus thuringiensis. There have been concerns that Bt corn hybrids produce residues that are relatively resistant to decomposition. We conducted four experiments that examined the decomposition of corn residues under field conditions. We found no differences in residue decomposition between Bt and non-Bt corn hybrids.
