Predicting Spatial Variability of Soil Organic Carbon in Delmarva Bays
… health, and wetland restoration rely on soil organic carbon (SOC) as vital for microbial activity and plant health. This study assessed: (1) accuracy of topographic-based non-linear models for predicting SOC; and (2) the effect of analytic strategies and soil condition on performance of …

Optimization Techniques for Soil Organic Carbon Prediction Using Mid-Infrared Spectroscopy
<p>Resource-efficient techniques for accurate soil carbon estimation are necessary to satisfy the increasing demand for spatiotemporal data. In the last thirty years, mid-infrared (MIR) soil spectroscopy has developed as an accurate, rapid, cost-effective, and non-destructive technique for soil …

Tillage Effects on Soil Organic Carbon Sequestration: Carbon Inputs and Physical Protection
… of NT practice adoption, C input patterns and soil aggregation could explain SOC contents that were increased at the surface and decreased in the subsurface depth of the NT soil.

Sequestration and Characterization of Soil Organic Carbon for Shelterbelt Agroforestry Systems in Saskatchewan
The increase in atmospheric concentration of carbon dioxide (CO₂) is contributing to global climate change. Agroforestry systems, such as shelterbelts, can contribute to the mitigation of increasing CO₂ levels, through carbon (C) sequestration in plant biomass and soils. However, little information …

SOIL ORGANIC CARBON IN MID-ATLANTIC REGION FOREST SOILS: STOCKS AND VERTICAL DISTRIBUTION
Soil contains the largest terrestrial pool of organic carbon (Boschi et al., 2018) and temperate forest soils have been a major sink for atmospheric carbon; however, determining the size of the soil organic carbon stock can be problematic. Sampling practices vary for sampling depth, and determining …

Effect of mass wasting on soil organic carbon storage and coastal erosion in permafrost environments
… underlain by permafrost store high amounts of soil organic carbon (SOC). Permafrost disturbances may contribute to increased release of carbon dioxide and methane to the atmosphere. Coastal erosion, amplified through a decrease in Arctic sea-ice extent, may also mobilise SOC from permafrost. …

Towards a paradigm shift in the modeling of soil organic carbon decomposition for earth system models
<p>Soils are the largest terrestrial carbon pools and contain approximately 2200 Pg of carbon. Thus, the dynamics of soil carbon plays an important role in the global carbon cycle and climate system. Earth System Models are used to project future interactions between terrestrial ecosystem carbon …

Environmental change and soil organic carbon storage in a dust emission hotspot, Free State, South Africa
… which may contribute to dust emissions and soil loss, a common symptom of land degradation. The goal of this study was to establish how the shift in land cover or land use change affects the occurrence of dust and determine the climate constraints and mitigations to crop production with …

Soil Organic Carbon Variability by Aspect and Slope in the High Elevation Soils of the Southwest Virginia Mountains
Limited information is available on carbon(C)sequestered in frigid Appalachian forest soils. However,the cool moist forests of the high elevations probably hold more C than any other mineral soils in Virginia. The objectives of the study were to determine the amount and variability of soil C across …

Characterization of spatial distribution of soil organic carbon stocks in selected land use types and landscapes in Chama District
Soil Organic carbon (SOC) because of its influence on all aspects of soil fertility, is a useful indicator of soil health and the performance of mixed farms, and increasing SOC can improve productivity, stability and resilience of the soil. Thus the overall objective of the study was to …

Chemical Characterization of the Degradation of Necromass from Four Ascomycete Fungi: Implications for Soil Organic Carbon Turnover and Storage
Terrestrial soils store approximately twice as much carbon as is currently in the atmospheric CO2 pool. Despite its importance in the global carbon cycle, much is still unknown about the source, turnover, and stability of the soil organic matter (SOM) pool. For example, fungi are known to play an …

Land-use change effects on soil organic carbon, total soil nitrogen, and soil erosion in a temperate forest and grassland
… several factors that influence the retention of soil organic carbon (SOC) and total soil nitrogen (TSN) including soil texture, climate, slope length and gradient, and current and past land-use. The purpose of this study was to compare by land use the retention of SOC and TSN on sloping …

Fire and herbivory effects on soil organic carbon stocks and soil greenhouse gas emissions from South African grasslands and savannas: Implications for global change
Understanding drivers of soil organic C (SOC) stocks and soil greenhouse gas emissions in grassland and savanna ecosystems is critical for climate change mitigation considering that soils are large C reservoirs while functioning as sinks and sources of the principal soil greenhouse gases, carbon …
