Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations
acidic soils adsorption desorption organic matter risk elements
2015/3/13
The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of t...
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...
Influence of the degree of soil organic matter lability on the calcium carbonate equilibrium of soil water

2015/3/2
In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate consta...
Potential and limitations of soil organic matter build-up in dry areas
Green manure soil organic matter water infiltration water stable aggregates

Semi-arid areas comprise a large portion of the world’s agricultural crop land. These areas are characterised by high temperature and low rainfall which hinders soil organic matter accumulation.
Loss on ignition: Measuring soil organic carbon in soils of the Sahel, West Africa
Loss on ignition Sahel Mali Africa carbon sequestration
2011/1/13
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...
Changes the content of organic matter in soil during the whole cycle of crop rotation
soil humidity soil organic matter crop rotation
2010/1/19
The ecological crop rotation in the present trial has been established as a 10-field
rotation. The crop sequence was based on calculation of how much of the nutrients does one or
another crop take...

2009/3/12
A laboratory experiment was conducted to document the effect of organic and inorganic amendments on soil P fractions under submerged conditions and to gain understanding of the changes in different P...
Organic Soils Continue to Acidify Despite Reduction in Acidic Deposition
Organic Soils Reduction Acidic Deposition
2009/12/16
Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effec...
Effect of Organic and Bio-fertilizers on Phosphorus and Some Micronutrients Availability in a Calcareous Soil
Arbuscular mycorrhizal fungi (AM infection) organic compost phosphorus
2010/11/11
The results obtained clearly show that the combined treatment of (AM+ organic compost) significantly increased the released P and micronutrients in the soil. This may be due
to lowering soil pH and f...
