Effect of agricultural lands afforestation and tree species composition on the soil reaction, total organic carbon and nitrogen content in the uppermost mineral soil profile
acidification afforestation carbon nitrogen soil reaction
2015/3/10
Forests occupy one third of the world’s land area and govern carbon (C) transfers and influence nitrogen (N) content in the biosphere. Afforestation leads to soil changes of specific dynamics, often a...

Traditional methods of measuring soil organic carbon (SOC) are not adequate for accurate evaluation of C sequestration nor to meet environmental safety requirements. Methods that permit accurate asses...
Organic and inorganic carbon stocks and balance of Adana city soils in Turkey
Adana soils soil organic carbon amounts and stocks
2011/1/12
Carbon stocks are calculated between from 0 - 100 cm depths of Adana great soil groups (GSG). Total carbon stock is 567.19 Tg in 0 - 100 cm, 168.37 Tg of which is organic carbon (OC) and 398.83 Tg of ...
Land use effect on soil and particulate organic carbon, and aggregate stability in some soils in Tunisia
Land use soil organic carbon particulate organic carbon
2011/1/11
Conversion of native forests to cultivation is usually accompanied by a decline in soil organic carbon and nutrients, and deterioration of soil structure. Our knowledge of this process must increase i...
Calcium Helps Evaluate Soil's Ability to Retain Earth's Carbon
Calcium Soil's Ability Earth's Carbon
2009/12/16
Soils play a vital role in dealing with the environmental impacts of rising atmospheric carbon levels, primarily CO2, from natural and human activities. The Earth's carbon budget is a dynamic process....
