.soil microorganisms are important agents in nutrient cycling and energy flow. they are extremely sensitive to environmental changes. soil microbial biomass has been proposed as an index of soil stress and disturbance. the objective of this study was to determine the effects of barley (hordeum vulgare l.) residue amounts, burning, nitrogen fertilizer levels and tillage management on organic car...

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. This area is arounding sa...

Abstract Climate change and increase of global warming is one of the most important challenges in sustainable development, which is due to increase of concentration of greenhouse gasses and CO2 in atmosphere. Rangelands have approximately half of the worlds land area and store over third of terrestrial biosphere carbon. Therefore they have a large potential to sequester carbon. In this order, c...

Soils were collected from a broad leaf-Pinus massoniana mixed forest, a Chinese fir (Cunninghamialan ceolata)-Pinus massoniana mixed forest, and a pure Pinus massoniana subtropical forest for subsequent analyses to compare characteristics of soil organic carbon and microbial biomass carbon content. Soil organic carbon mineralization characteristics were further modeled using a double exponentia...

[1] The oxidative ratio (OR) of the net ecosystem carbon balance is the ratio of net O2 and CO2 fluxes resulting from photosynthesis, respiration, decomposition, and other lateral and vertical carbon flows. The OR of the terrestrial biosphere must be well characterized to accurately estimate the terrestrial CO2 sink using atmospheric measurements of changing O2 and CO2 levels. To estimate the O...

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...
