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 adoption of recommended technologies depends on soil texture and structure, rainfall, temperature, farming system, and soil management. Strategies to increase the soil carbon pool include soil restoration and woodland regeneration, no-till farming, cover crops, nutrient management, manuring and sludge… 

SOIL CARBON SEQUESTRATION TO MITIGATE CLIMATE CHANGE AND ADVANCE FOOD SECURITY

World soils have been a source of atmospheric carbon dioxide since the dawn of settled agriculture, which began about 10 millennia ago. Most agricultural soils have lost 30% to 75% of their

Enhancing Carbon Sequestration Using Organic Amendments and Agricultural Practices

Carbon sequestration (CS) is an important strategy for the mitigation of climate change (CC) as well as for improving the soil fertility of agricultural soils. Carbon sequestration in crop lands and

Soil management practices for sustainable agro-ecosystems

A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural

Global crop production increase by soil organic carbon

Soil organic carbon sequestration has been promoted to combat climate change while improving soil fertility. However, its quantitative contribution to crop productivity has proven elusive. Using data

Carbon Sequestration in Alkaline Soils

Healthy soils ensure food security through sustainable agricultural production and also support in mitigating the climate change hazardous like global warming and greenhouse gases emission. However,

Good Agricultural Practices and Carbon Sequestration

Conservation agriculture (CA) technologies include minimum soil disturbance, permanent soil cover through crop residues or cover crops, and crop rotations for achieving higher productivity. Intensive

Conservation Agriculture and Soil Carbon Sequestration

Changes to agricultural practices in response to climate change and widespread soil degradation are being investigated to improve food security, enhance environmental conservation, and achieve

Potential of Conservation Agricultural Practices on Soil Quality, Carbon Sequestration, Salinity Management and Productivity of Rainfed Areas

Intensive cropping, traditional tillage practices, and crop residue removal are the major factors of soil organic carbon (SOC) depletion. Restoration of SOC levels would improve the soil’s aggregate

Estimated land area increase of agricultural ecosystems to sequester excess atmospheric carbon dioxide

An estimated 3.3 Pg carbon (C) is accumulating in the atmosphere annually, with carbon dioxide (CO2) concentrations increasing approximately 1.5–2.0 ppm per year. The conversion of land to

Managing Soil Carbon

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

Quantifying short-term effects of crop rotations on soil organic carbon in southwestern Saskatchewan

Crop management practices can have a major influence on soil fertility and soil organic C (SOC) sequestration. We need to accurately measure and estimate changes in SOC in the short term (<20 yr). A
