SOIL CARBON DYNAMICS AND GLOBAL WARMING POTENTIAL OF SELECTED SOIL SERIES AND LANDUSE CATEGORIES

Results of multiple linear regression between leaf litter characteristics and the soil organic carbon stock in particulate organic carbon and mineral- -associated carbon fractions

Cm, Nm and Pm –microbial carbon, nitrogen and P; C – Soil organic carbon; Csag – water soluble carbon; Cdisp – available carbon ; Cmin – mineralizable carbon; Pil, Pol and Ptl

Crop residues (above and below ground) are the pri- mary source of carbon input in the soil carbon pool but crop rotation can also impact the plant biomass returned to the

Annual carbon sequestration rates in whole soil (0–0.30 m) and in particulate organic carbon (POC) and mineral-associated organic carbon (MAOC) of a subtropical Oxisol under two

The soil samples were used to estimate the soil microbial biomass carbon and nitrogen, soil basal respiration, metabolic quotient and soil enzymatic activity, through hydrolysis

Relationships between soil pH bu ff ering capacity (pHBC) and soil variables (cation exchange capacity (CEC), soil organic carbon (SOC), soil clay content, soil pH, soil inorganic

Levels of total soil organic carbon, as well as oxidizable fractions and aggregate stability, were analyzed, in addition to the activity and carbon and nitrogen content in the

In addition, adding PS to the soil to support nutrient cycling can also increase soil carbon concentrations (CT) over time 3,4 and may change the composition of carbon
