Changes in agricultural management can potentially increase the accumulation rate of soil organic C (SOC), thereby sequestering CO 2 from the atmosphere. This study was conducted to quantify potential soil C sequestration rates for different crops in response to decreasing tillage intensity or enhancing rotation complexity, and to estimate the duration of time over which sequestration may occur. Analyses of C sequestration rates were completed using a global database of 67 long-term…

The effectiveness of no-till (NT) farming in reducing loss of soil organic matter (SOM) depends on climate and soil properties. Soil samples were obtained from two long-term experiments that were

Effect of cropping practices on soil organic carbon: evidence from long-term field experiments in Victoria, Australia

Despite considerable research, predicting how soil organic carbon (SOC) in grain production systems will respond to conservation management practices, such as reduced tillage, residue retention and

No-Till Systems to Sequester Soil Carbon: Potential and Reality

The conversion of soils from conventional till (CT) to no-till (NT) management has been identified as a soil management practice with the potential to increase soil organic carbon (SOC) sequestration

Long-Term Soil Organic Carbon Changes as Affected by Crop Rotation and Bio-covers in No-Till Crop Systems

Soil organic carbon (SOC) sequestration is a potential negative-feedback for climate-warming gases in agriculture. The rate of no-tillage SOC storage is not well known due to large temporal and

A review on carbon pools and sequestration as influenced by long-term management practices in a rice–wheat cropping system

ABSTRACT The drastic increase of atmospheric CO2 concentrations and depletion of soil organic carbon (SOC) have prompted interest in exploiting the sink potential of soil to sequester carbon. The

Continuous No-Till Impacts on Soil Biophysical Carbon Sequestration

Increasing C sequestration through no-till (NT) can reduce agricultural CO₂ emissions. However, for long-term NT, information is lacking on the effect of biophysical C pools and processes on C

Land-Use Intensity Effects on Soil Organic Carbon Accumulation Rates and Mechanisms

Restoring soil C pools by reducing land use intensity is a potentially high impact, rapidly deployable strategy for partially offsetting atmospheric CO2 increases. However, rates of C accumulation

Crop rotations and nitrogen fertilization to manage soil organic carbon dynamics.

Sustainability is influenced in many production systems by the variation of soil organic C (SOC) content and dynamics, and crop rotations. We hypothesized that arable layer SOC under conventional

Rotation and Nitrogen Fertilization Effects on Changes in Soil Carbon and Nitrogen

Long-term effects of cropping systems on soil properties, such as organic soil C and N levels, is necessary so more accurate projections can be made regarding the sequester and emission of CO 2 by

Adopting zero tillage management: Impact on soil C and N under long-term crop rotations in a thin Black Chernozem

Society’s desire to sequester C in soils, thereby reducing the net loss of CO2 (a greenhouse gas) to the atmosphere, is well known. It is also accepted that the choice of appropriate agricultural

Management options for reducing CO2 emissions from agricultural soils

Crop-based agriculture occupies 1.7 billion hectares, globally, with a soil C stock of about 170 Pg. Of the past anthropogenic CO2 additions to the atmosphere, about 50 Pg C came from the loss of

Conservation Tillage Impacts on National Soil and Atmospheric Carbon Levels

Soil organic matter is the largest global terrestrial C pool and is a source of CO₂, CH₄, and other greenhouse gases. Changes in soil organic C (SOC) content and fossil fuel C emissions inresponse to
