Evaluation of Dissolved Organic Carbon as a Soil Quality Indicator in National Monitoring Schemes
BACKGROUND Monitoring the properties of dissolved organic carbon (DOC) in soil water is frequently used to evaluate changes in soil quality and to explain shifts in freshwater ecosystem functioning. METHODS Using >700 individual soils (0-15 cm) collected from a 209,331 km(2) area we evaluated the relationship between soil classification (7 major soil types) or vegetation cover (8 dominant cla...
متن کاملSoil organic matter as sole indicator of soil degradation.
Soil organic matter (SOM) is known to play vital roles in the maintenance and improvement of many soil properties and processes. These roles, which largely influence soil functions, are a pool of specific contributions of different components of SOM. The soil functions, in turn, normally define the level of soil degradation, viewed as quantifiable temporal changes in a soil that impairs its qua...
متن کاملSoil organic matter stratification ratio as an indicator of soil quality
Soil quality is a concept based on the premise that management can deteriorate, stabilize, or improve soil ecosystem functions. It is hypothesized that the degree of stratification of soil organic C and N pools with soil depth, expressed as a ratio, could indicate soil quality or soil ecosystem functioning, because surface organic matter is essential to erosion control, water infiltration, and ...
متن کاملSoil Organic Matter Quality From Soils Cropped by Traditional Peasants
In this work we have analyzed soil samples from Oxisols collected from two traditional communities, one formed by Guarany Indians at South of Brazil and other by African descendants on North of Rio de Janeiro State, Brazil. The content and fractional composition of humus was investigated and the isolated humic acids (HAs) were characterized by elemental composition, C solid-state nuclear magnet...
متن کاملOrganic Residues A Resource for Arable Soils
Odlare, M. 2005. Organic Residues – a Resource for Arable Soils. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-6970-8. An increased recirculation of urban organic residues to arable soils has several environmental benefits, but there is a need for reliable test systems to ensure that soil quality is maintained. In this thesis, soil microbial, chemical and physical properties were included ...
