Sequestering of Atmospheric Carbon through Permanent Disposal of Crop Residue

Abstract

We propose the sequestering of crop residues to capture a significant fraction(12%) of the present U.S. atmosphericcarbon emission through disposal in deep oceans below the thermocline or inriver deltas. In the United States, theannual carbon content in residues from corn, soybeans and wheat crops isapproximately 250 million tonnes. Globally, an additional 1 billion tonnes of carbon in the form of cropresidues may be available. Implementation ofthis sequestering proposal would allow the US to approach the CO2reductions stipulated under the KyotoProtocol.
