Current farming practices deplete soil carbon, which degrades soil quality, reduces productivity, and results in the need for more fertilization, irrigation, and pesticides. No-till farming with residue mulching would reverse these effects by slowing soil erosion and pollution runoff, benefiting aquatic ecosystems, improving agronomic productivity, and achieving food security. The authors of this Policy Forum urge support for its wider use. Although there may be short-term yield reductions in… 

Challenges and Opportunities of Soil Organic Carbon Sequestration in Croplands

This chapter reviews the main farming practices related with soil organic carbon (SOC) sequestration in croplands, aimed, simultaneously, at improving soil quality and health, and reducing net

Field Plots and Crop Yields Under Innovative Methods of Carbon Sequestration in Soil

This chapter reviews the issues related to the responses of crops and soil fertility to management strategies aimed to conserve soil carbon, especially for Mediterranean-Temperate conditions. It

Persistent soil carbon enhanced in Mollisols by well-managed grasslands but not annual grain or dairy forage cropping systems

Significance Soil organic carbon (C) responses to agricultural management are highly uncertain, hindering our ability to assess the C sequestration potential of croplands and develop sound policies

The carbon sink capacity of the world's agricultural and degraded soils is 50 to 66% of the historic carbon loss of 42 to 78 gigatons of carbon. The rate of soil organic carbon sequestration with

Crop Residue Management and Soil Carbon Dynamics

Crop residues, comprising both aboveand belowground biomass fractions remaining in the fi eld aft er harvest, infl uence the global carbon cycle and terrestrial carbon budget. The soil organic carbon

Soil carbon (C) sequestration implies transferring of atmospheric CO2 into soil of a land unit through its plants. Co-benefits of soil C sequestration include: advancing food and nutritional



Legume-based cropping systems have reduced carbon and nitrogen losses

In agricultural systems, optimization of carbon and nitrogen cycling through soil organic matter can improve soil fertility and yields while reducing negative environmental impact. A basic tenet that

Managing U.S. cropland to sequester carbon in soil

The effects of human activities on atmospheric concentrations of carbon dioxide (CO2) and other greenhouse gases (GHGs) are under intensive study in the United States and worldwide. Since conversion

Soil organic carbon sequestration rates by tillage and crop rotation : A global data analysis

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

Quantification of the effect of soil organic matter content on soil productivity

The positive effects of soil organic matter (OM) on soil properties that influence crop performance are well documented. But definitive and quantitative information of differential effects of soil OM

Sustainable agriculture and the international rice-wheat system.

Addressing a topic of major importance to the maintenance of world food supplies, this reference identifies knowledge gaps, defines priorities, and formulates recommendations for the improvement of

Considering Manure and Carbon Sequestration

In his Policy Forum “Carbon sequestration in soils” (25 June 1999, p. [2095][1]), William H. Schlesinger notes that manure application has been suggested as a possible mechanism for soil carbon

Budgets of soil erosion and deposition for sediments and sedimentary organic carbon across the conterminous United States

The fate of soil organic matter during erosion and sedimentation has been difficult to assess because of the large size and complex turnover characteristics of the soil carbon reservoir. It has been
