The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock

  Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...

Soil organic carbon dynamics jointly controlled by climate, carbon inputs, soil properties and soil carbon fractions.

Soil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively. Using observations of SOC dynamics with detailed soil properties from 90 field trials at 28 sites under different agroecosystems across the Australian ...

Prediction of Soil Organic Carbon across Different Land-use Patterns: A Neural Network Approach

ecosystem type and soil taxonomy has been compared, and the taxonomic approach appeared to be more meanMathematical modeling has widely been used to predict soil organic ingful in creating a real picture of spatial distribution carbon (SOC). However, there are characteristics of the models such as over simplification, ignorance of complex nonlinear interactions of SOC. Attempts have been made t...

Tillage Effects on Soil Organic Carbon Fractions in Mediterranean

influence of vegetation type and land management on soil organic carbon fractions in gonbad watershed, hamadan

introduction: soil organic matter is influenced strongly by vegetation cover and management, therefore it is proposed as the main indicator of soil quality and health. the changes in soil organic matter status occur much more rapidly in the labile pools than in organic c. thus, labile pools can be used as early indicators of changes in total organic matter that will become more obvious in the l...
