Objective: Soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. Organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. So, this research has been done for achieving this purpose. Methods: This...

Abstract Background and objectives: Access to real information and data on the impact of watershed management projects and their technical and economic evaluation is possible through representative and paired catchments. Since management operations and topographic characteristics have a great impact on carbon retention in ecosystems, this study aimed to determine the amount of soil organic ca...
Reduction of quality and soil productivity due to organic carbon losses is one of the most important consequences of land use changes, that creates irreparable effects on the soil. To evaluate the land use effect on the amount of soil organic carbon in Vertisols, Sartip Abad series with extent of 1850 hectare in south of Bilehvar area in Kermanshah province was studied by using the completely r...
organic matter and its related soil properties are among the most important indicators of soil quality. despite the importance of soil organic carbon, no comprehensive study has been done on organic carbon changes in soils of the isfahan province. the objective of this research was to investigate factors affecting soil organic carbon in soils of this province. a total of 248 surface soil sample...
