High-resolution Quaternary record of marine organic carbon content in the hemipelagic sediments of the Japan Sea from bromine counts measured by XRF core scanner

Progress in Earth and Planetary Science, 2019
The marine organic carbon content in sediments is a useful tool for reconstructing past productivity in the ocean. Bromine has been proposed as a useful proxy for marine organic carbon, since bromine is more concentrated in marine organic matter compared

Greater mineral and aggregate protection for organic carbon in the soil amended by weathered coal than by biochar: Based on a 3-year field experiment

Geoderma, 2023
Soil carbon pool stability plays an important role in reaching carbon neutrality and mitigating global warming. Applying soil amendments is a practical strategy in agricultural production to improve soil environment.

Soil organic carbon and particulate carbon in water in riparian systems under different land use

Terra Latinoamericana, 2021
Overexploitation of hydric resources and lack knowledge of interactions between riparian vegetation, water and soil, generates loss of environmental services and ecological degradation in many mountainous riparian environments. In order to characterizing

Organic Carbon Density and Its Influencing Factors in Caofeidian Seagrass Bed Sediments, China [PDF]

E3S Web of Conferences
Seagrass ecosystems capture and store a large amount of carbon every year. However, co-mpared with other ecosystems, research on deep sediment carbon pools in China 's seagrass ecosystem is still relatively scarce.

CARBON CONTENTS AND MODELLING OF TOTAL ORGANIC CARBON FOR Pinus taeda L. FROM NATURAL REGENERATION [PDF]

Revista Árvore, 2016
ABSTRACT This study aimed to quantify total carbon and its compartments: roots, stems, branches, and aciculas, in order to select an estimated equation of the total organic carbon for Pinus taeda L. settled from natural regeneration in the forest understory of a planted forest in the municipality of Três Barras, SC.

Long-Term Application of Manure and Different Mineral Fertilization in Relation to the Soil Organic Matter Quality of Luvisols

Agronomy, 2023
Long-term field experiments were conducted on luvisol at five sites in the Czech Republic (42–48-year duration). The average total organic carbon content in the soil varied between 9.0 and 14.0 g kg−1.
