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 ...

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...

Improved management of soil carbon (C) and nitrogen (N) storage in agro-ecosystems represents an important strategy for ensuring food security and sustainable agricultural development in China. Accurate estimates of the distribution of soil C and N stores and their relationship to crop yield are crucial to developing appropriate cropland management policies. The current study examined the spati...

The aim of this study was to evaluate the stock total organic carbon (TOC) and perform physical-granulometric fractionation soil matter (SOM) in different management systems (MS). Three MS one reference area Native Forest (NF) were studied, three sugarcane (SC), permanent pasture (PP) no-tillage system (NTS). Soil samples collected 0–0.05, 0.05–0.10, 0.10–0.20-m layers. density (Sd), TOC, strat...

In Colombia, the rise of agricultural and pastureland expansion continues to exert increasing pressure on structure ecological processes savannahs in Eastern Plains. However, effect land use change soil properties is often unknown due poor access remote areas. Effective management conservation soils requires development spatial approaches that measure predict dynamic such as organic carbon (SOC...

Thawing of permafrost and the associated release of carbon constitutes a positive feedback in the climate system, elevating the effect of anthropogenic GHG emissions on global-mean temperatures. Multiple factors have hindered the quantification of this feedback, which was not included in climate carbon-cycle models which participated in recent model intercomparisons (such as the Coupled Carbon ...

Blue carbon habitats, such as mangroves and salt marshes, have been recognized burial hotspots; however, methods on measuring blue stocks varied thus leave uncertainty in global stock estimates. This study analyzes northern Florida wetlands along the Atlantic Gulf coasts. Carbon measurements within 1–3m length vibracores yield total core of 9.9–21.5 kgC·m −2 7.7–10.9 for coast cores, respective...
