Application of Path Analysis on Soil Organic Carbon and Soil Aggregate Analysis

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...

Aggregate and soil organic carbon dynamics in South Chilean Andisols

Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata p...

Effect of Agronomic Practices on the Aggregate Stability and Organic Carbon of soil (Case study: the Northern of Aq Qala)

Soil and soil organic carbon redistribution on the landscape

Patterns of soil organic carbon (SOC) vary widely across the landscape leading to large uncertainties in the SOC budget especially for agricultural landscapes where water, tillage and wind erosion redistributes soil and SOC across the landscape. It is often assumed that soil erosion results in a loss of SOC from the agricultural ecosystem but recent studies indicate that soil erosion and its su...

Addition of External Organic Carbon and Native Soil Organic Carbon Decomposition: A Meta-Analysis

BACKGROUND Extensive studies have been conducted to evaluate the effect of external organic Carbon on native soil organic carbon (SOC) decomposition. However, the direction and extent of this effect reported by different authors is inconsistent. OBJECTIVE The objective was to provide a synthesis of existing data that comprehensively and quantitatively evaluates how the soil chemical propertie...
