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… 
To Bury or to Burn: Optimum Use of Crop Residues to Reduce Atmospheric CO2
We argue that sequestering of carbon waste is inherently more efficient andwill probably cost less than using the carbon for biomass burning. The ratioof carbon emitted per unit of primary energy
Ocean sequestration of crop residue carbon: recycling fossil fuel carbon back to deep sediments.
This paper shows that removal of crop residues and burial in the deep ocean is 92% efficient in sequestration of crop residue carbon while cellulosic ethanol production is only 32% efficient, and soil sequestration is about 14% efficient.

Abstract: Carbon sequestration in terrestrial ecosystems, comprising soils and biota, is one of several possible strategies being considered to stabilize atmospheric concentration of CO 2 and other
Achieving negative emissions through oceanic sequestration of vegetation carbon as Black Pellets
Natural processes and human activities produce vast amounts of dead vegetation which return CO2 to the atmosphere through decay and combustion. If such vegetation could be converted into biocoal and
The Global Potential for Carbon Dioxide Removal
The global physical potential of different methods of carbon dioxide removal (CDR) from the atmosphere is reviewed. A new categorisation into plant-based, algal-based and alkalinity-based approaches
The need for new ocean conservation strategies in a high-carbon dioxide world
The threats posed to the marine environment by increasing atmospheric carbon dioxide are historically unprecedented, and will probably require the use of unconventional, non-passive methods to
Bioenergy and CO2 Sequestration: Climate Policies Beyond Technological Constraints
This paper examines the role of electricity production from biomass with and without carbon capture and storage in sustaining low CO2 emission pathways to 2100. It quantifies the effect of the


Fossil Fuels Without CO2 Emissions
Recent work in carbon management (CM)--the separation and sequestration of carbon from fossil-fuel combustion to reduce atmospheric COemissions--has raised estimates of sequestration capacities and

Turning Great Plains crop residues and other products into energy.
Crop residues, such as corn stover, grain sorghum stover, and wheat straw, are abundant sources of fuel energy in the 10-State Great Plains region. These ' residues and other wastes, such as manure,
Dynamical limitations on the Antarctic iron fertilization strategy
MARTIN et al. have proposed an ingenious means by which the rise in atmospheric CO2 content generated by the burning of fossil fuels and deforestation might be partially compensated1. The idea is
Energy implications of future stabilization of atmospheric CO2 content
The United Nations Framework Convention on Climate Change calls for “stabilization of greenhouse-gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic
Carbon dioxide effects: research and assessment program. Workshop on the global effects of carbon dioxide from fossil fuels
Current knowledge of the CO/sub 2/ cycle and the consequences of increases in CO/sub 2/ content of the atmosphere are discussed. Significant gaps in our understanding are identified and actions to
Carbon sequestration in a Brown Chernozem as affected by tillage and rotation
Soil organic matter is important because it influences the productivity and physical well-being of soils. Recently, increased attention has focussed on soil organic matter as a possible sink for

Land‐use change and the carbon cycle
Changes in land use between 1850 and 1980 are estimated to have increased the global areas in croplands, pastures, and shifting cultivation by 891, 1308, and 30 × 106 ha, respectively, reducing the
