Carbonating magnesia for soil stabilization

Canadian Geotechnical Journal, 2013
This paper investigates the potential for carbonating reactive magnesia (MgO) to serve as a more sustainable soil stabilization method by providing rapid and significant strength development of the stabilized soil through absorbing substantial quantities of CO2.

Accounting for two-billion tons of stabilized soil carbon

Science of The Total Environment, 2020
The pedosphere is the largest terrestrial reservoir of organic carbon, yet soil-carbon variability and its representation in Earth system models is a large source of uncertainty for carbon-cycle science and climate projections. Much of this uncertainty is attributed to local and regional-scale variability, and predicting this variation can be ...

Stability of elemental carbon in a savanna soil

Global Biogeochemical Cycles, 1999
We have investigated the stability of oxidation‐resistant elemental carbon (OREC) in a sandy savanna soil at the Matopos fire trial site, Zimbabwe. The protection of some soil plots from fire for the last 50 years at this site has enabled a comparison of OREC abundances between those plots which have been protected from fire and plots which have ...

Applying Multiwall Carbon Nanotubes for Soil Stabilization

Procedia Engineering, 2015
AbstractThe chemical stabilization of a soil is a technique where the soil is mixed with cementitious material in order to improve its mechanical behavior. The chemical stabilization is dependent on a wide range of parameters, being the most important ones associated to the soil properties and cementitious material characteristics.

Stabilization of carbon in composts and biochars in relation to carbon sequestration and soil fertility

Science of The Total Environment, 2012
There have been increasing interests in the conversion of organic residues into biochars in order to reduce the rate of decomposition, thereby enhancing carbon (C) sequestration in soils. However energy is required to initiate the pyrolysis process during biochar production which can also lead to the release of greenhouse gasses.

Stability of soil organic carbon in the subsoil

2021
Soils contain the largest carbon (C) pool of the global terrestrial carbon cycle and can act as sources or sinks for CO2. Although, more than 50 % of the global soil organic carbon (SOC) stocks are stored in subsoils (> 30 cm deep) and the high mean residence time of subsoil organic carbon (OC) indicates that SOC in subsoils is more stable than in ...

Glomalin: A Key Indicator for Soil Carbon Stabilization

2021
In the last decades, many studies were addressed focusing on soil protection that helps sequestration and stabilization of organic carbon in soil aggregates. Soil aggregates are an association of primary soil particles, bacteria, fungi, plant root and soil organic matter.

Effects of carbon input on soil carbon stability and nitrogen dynamics

Agriculture, Ecosystems & Environment, 2014
Abstract Improved understanding of the process of carbon (C) stabilization is critical to managing emissions from agricultural soils and optimizing crop yield. We assessed soil organic C (SOC) stability and nitrogen (N) dynamics in a long-term fertilization experiment (started in 1972) conducted at three different locations in India (Jabalpur ...

Microbial regulation of soil carbon stabilization shapes soil carbon projections

Enhancing SOC accumulation is considered as a pathway for mitigating climate change. However, projection of soil organic carbon (SOC) exhibits large uncertainties, and microbial activities, the key regulator of SOC dynamics, are omitted in most Earth System Models (ESMs).

Soil pH Modulates the Global Stabilized Soil Organic Carbon

Global Change Biology
ABSTRACT Soil mineral‐associated organic carbon (MAOC) constitutes over 50% of total soil organic carbon (SOC) and serves as a key determinant of its long‐term stabilization. Although soil pH is recognized as a “master variable” in biogeochemical cycles, it remains unclear how soil pH influences MAOC and SOC at large spatial scales ...
