Geogenic organic carbon in terrestrial sediments and its contribution to total soil carbon [PDF]

SOIL, 2021
Geogenic organic carbon (GOC) from sedimentary rocks is an overlooked fraction in soils that has not yet been quantified but influences the composition, age, and stability of total organic carbon (OC) in soils.

Determination of Total Organic Carbons by Ion Chromatography

Analytical Sciences, 1991
A method for indirect UV detection of carbonate in solution using potassium phthalate as eluent has been developed. The detection limit for carbonate is 0.5mg/l in solution. The application of the analytical method developed to the analysis of trace organic carbon in deionised water and total carbon in air particulate was investigated and the results ...

Porosity and storage capacity of Middle Devonian shale: A function of thermal maturity, total organic carbon, and clay content

Fuel, 2019
Porosity and pore size distribution (PSD) are critical reservoir parameters. Pore surface area, pore volume, PSD, and porosity were measured using subcritical nitrogen (N2) adsorption, and helium porosimetry.

Global stocks and capacity of mineral-associated soil organic carbon

Nature Communications, 2022
Soil is the largest terrestrial reservoir of organic carbon and is central for climate change mitigation and carbon-climate feedbacks. Chemical and physical associations of soil carbon with minerals play a critical role in carbon storage, but the amount ...

Losses of soluble forms of organic carbon in relation to different agro-technical treatment of meadows

Soil and Water Research, 2016
Studies were performed to determine the loss of soluble forms of organic carbon in differently used meadows on mineral soil. In a long-term experiment two variants were distinguished: a productive meadow (N120-AN and N120-CN) and a non-productive one (Kp-

Carbon dynamics in no-till soil due to the use of industrial organic waste and mineral fertilizer

Revista Ciência Agronômica
The use of organic waste from industrial processes in agriculture is a strategy not only for improving soil properties but also for promoting the utilization of recycled nutrients by market crops and for reducing environmental impact.

Carbon sequestration potential of tea garden soil in northwest Zhejiang and its accumulation characteristic on different fractions of organic carbon

浙江大学学报. 农业与生命科学版, 2016
Organic carbon is the basis of soil system, which plays an important role in the soil quality and regulating the supply of nutrients. Physical, chemical and biological properties and productivity of soil were all closely related to the content and ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
