Carbon organic matter

Fluxes are linear functions of reservoir contents. Reservoir size and the residence time of the carbon in the reservoir are the parameters used in the functions. Between the ocean and the atmosphere and within the ocean, fluxes rates are calculated theoretically using size of the reservoir, surface area of contact between reservoirs, concentration of CO2, partial pressures of CO2, temperature, and solubility as factors. The flux of carbon into the vegetation reservoir is a function of the size of the carbon pool and a fertilization effect of increased CO2 concentration in the atmosphere. Flux from vegetation into the atmosphere is a function of respiration rates estimated by Whittaker and Likens (79) and the decomposition of short-lived organic matter which was assumed to be half of the gross assimilation or equal to the amount transferred to dead organic matter. Carbon in organic matter that decomposes slowly is transferred... 

Soil properties A Soil texture (sand, silt, clay), organic matter/carbon content, and pH Stones, roots, and hardpans must be largely absent to allow representative sampling of soil profile Soil properties should appear uniform over test site Soil texture data should be available at time of site selection. Soil properties must match study purpose. This can be realistic use conditions, realistic worst-case or worst-case in terms of agrochemical mobility and persistence Must ensure that the majority of samples can be taken from the deepest sampling horizon. Information about sub-soils can be obtained from soil maps, test coring and on-site interviews...

ChemPete, Inc., bioremediation is an effective and continuous cleanup method for transforming gasoline, diesel fuel, fuel oil, kerosene, and chlorinated solvents to nonhazardous organic matter, carbon dioxide, and water, according to the vendor. ChemPete uses bacteria, nutrients, and a catalyst developed by Alpha Environmental Biosystems, Inc. ChemPete was the first company to achieve closure of both gasoline and fuel oil sites in situ in accordance with Illinois rigorous closure guidelines (5 parts per billion benzene). RIMS was unable to contact the vendor, and the commercial availability is unknown.

This view of the likely acids involved in creating Precambrian soils on Earth is supported by the isotopic composition of carbon, nitrogen, and sulfur in sedimentary organic matter, carbonates, sulfates, and sulfides, which are surprisingly similar to their modem counterparts back to 3,500 Ma, and unlike meteoritic or mantle values (Schidlowski et al, 1983 Des Marais, 1997 Canfield and Teske, 1996). 

The Israeli oil shales may be considered as a multi-variabled system, in which the main components influencing their quality are organic matter, carbonate, clay minerals and apatite. As the percentage of these components varies over the vertical section, depth also plays a significant role whenever a quality assessment of the shale is made. Compositional variations within the organic matter are responsible for changes in the relative calorific value and retorted oil yield, while fluidized bed combustion is affected by the inorganic composition.
