TLDR
The role of agriculture in U.S. Greenhouse gas emissions is discussed in this paper, where the authors propose a win-win strategy to increase agricultural profits from environmental improvements.Abstract:

Soil carbon sequestration to mitigate climate change
TL;DR: In this article, the authors proposed a sustainable management of soil organic carbon (SOC) pool through conservation tillage with cover crops and crop residue mulch, nutrient cycling including the use of compost and manure, and other management practices.

Soil organic carbon sequestration rates by tillage and crop rotation : A global data analysis
Tristram O. West,Wilfred M. Post +1 more
TL;DR: In this article, the authors quantify potential soil organic carbon 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.

World Agriculture: Towards 2015/2030: An Fao Perspective
TL;DR: The FAO's latest assessment of the long-term outlook for the world's food supplies, nutrition and agriculture is presented in this paper, where the projections cover supply and demand for the major agricultural commodities and sectors, including fisheries and forestry.
Journal ArticleDOI
Greenhouse gases in intensive agriculture: contributions of individual gases to the radiative forcing of the atmosphere.
TL;DR: None of the annual cropping systems provided net mitigation, although soil carbon accumulation in no-till systems came closest to mitigating all other sources of GWP, and the late successional system, GWP was neutral because of significant methane oxidation.
Journal ArticleDOI
Review of greenhouse gas emissions from crop production systems and fertilizer management effects
TL;DR: A review of the available science on the effects of N source, rate, timing, and placement, in combination with other cropping and tillage practices, on GHG emissions was conducted as mentioned in this paper.

Journal ArticleDOI
The Strategy of Ecosystem Development
TL;DR: The principles of ecological succession bear importantly on the relationships between man and nature and needs to be examined as a basis for resolving man’s present environmental crisis.
Journal ArticleDOI
The global carbon dioxide flux in soil respiration and its relationship to vegetation and climate
TL;DR: In this article, measured rates of soil respiration from terrestrial and wetland ecosystems were used to define the annual global CO 2 flux from soils, to identify uncertainties in the global flux estimate, and to investigate the influences of temperature, precipitation, and vegetation.
Journal ArticleDOI
Total carbon and nitrogen in the soils of the world
TL;DR: In this article, a discrepancy of approximately 350 × 1015 g (or Pg) of C in two recent estimates of soil carbon reserves worldwide is evaluated using the geo-referenced database developed for the World Inventory of Soil Emission Potentials (WISE) project.

Biological Feedbacks in Global Desertification
William H. Schlesinger,James F. Reynolds,Gary L. Cunningham,Laura Foster Huenneke,Wesley M. Jarrell,Ross A. Virginia,Walter G. Whitford +6 more
TL;DR: Studies of ecosystem processes on the Jornada Experimental Range in southern New Mexico suggest that longterm grazing of semiarid grasslands leads to an increase in the spatial and temporal heterogeneity of water, nitrogen, and other soil resources, which leads to the desertification of formerly productive land.
Journal ArticleDOI
Quantitative effects of grazing on vegetation and soils over a global range of environments
TL;DR: In this article, the authors quantitatively assess factors relating to differential sensitivities of ecosystems to grazing by large herbivores, including species composition, aboveground net primary production (ANPP), root biomass, and soil nutrients of protected, ungrazed sites.
