Crop residues could power future energy or erode soil
Dr William E Larson of USDA ARS argues that while crop residues such as corn stalks and wheat straw could be used to generate energy, most residues should stay on fields to prevent erosion and protect waters. Using computer models, he estimates how much residue can be removed without long term soil damage, noting regional differences and long term planning needs.
