Dissolved Organic Carbon Fluxes under Bare Soil
Journal of Environmental Quality, 2007ABSTRACTThe flux of dissolved organic carbon (DOC) in soil facilitates transport of nutrients and contaminants in soil. There is little information on DOC fluxes and the relationship between DOC concentration and water flux in agricultural soils. The DOC fluxes and concentrations were measured during 2.5 yr using 30 automatic equilibrium tension plate ...

Spectrophotometric determination of organic carbon in soil
Communications in Soil Science and Plant Analysis, 1992Abstract A detailed study was made of the well‐known organic carbon determination that is based on measuring the absorbance of the green chromium(III) complex generated when organic matter is oxidized by potassium dichromate in acidic medium. The green chromic colour proved to be unstable, turning slowly to a violet colour.

Soil Organic Carbon and Carbon Dioxide Emission from an Organically Amended Hawaiian Tropical Soil
Soil Science Society of America Journal, 2009Application of organic manure (OM) to arable lands improves soil tilth. The objectives of this study were to: (i) simulate the effect of OM application rates (0, 168, 336, and 672 kg total N ha −1 ) and types (chicken [ Gallus domesticus ] and dairy ...

Soil organic carbon determination (SOC)
The methodology is used to determine the soil organic carbon content and hence evaluate the quality of soils. Soil organic carbon (SOC) refers only to the carbon component of organic compounds. It is important due to the major role that it plays in soil productivity and in climate change mitigation. This procedures is carried using NIRS methodology.Bortolazzo, Elena, Ruozzi, Fabrizio
