Applying biochar to forests as a carbon-negative technology holds great promise for sustainable forest management. However, given the inherently high carbon sequestration capacity of forest ecosystems, the potential impacts of biochar amendment on net ecosystem production (NEP) require careful evaluation. To address …

Mangrove restoration is being increasingly employed to restore degraded coastal ecosystems and strengthen blue carbon (C) sequestration. Nevertheless, total ecosystem carbon (TEC) evaluations often omit deep soils, causing inaccurate estimates of C stored in restored mangroves. This study investigated a 10–14-year chronosequence …

Root exudates represent a critical belowground carbon flux; however, direct field-based quantification of these rates on intact mangrove roots remains limited due to methodological challenges. Here, we present, to our knowledge, the first in situ evaluation of root exudation rates in a …

Abstract The increase in forest wood biomass is an important carbon sink in the biogeochemical carbon cycle. The effect of forest succession on carbon sequestration is essential for predicting the impact of future global warming. However, there are limited studies considering the …

• Extractable metals (Al, Fe, Ca, Mg) contributions on mangrove OC were studied. • Organo-metal coprecipitates are the best predictors of OC content in HF. • Stabilization of mangrove soil OC is enhanced by organo-metal coprecipitation. • Rapid inclusion of fresh mangrove-derived …

Abstract Prediction of the impact of anthropogenic disturbances and global change on organic carbon (OC) pools in mangrove soils requires a detailed understanding of the mechanisms underlying OC stabilization. Using density fractionation to physically separate OC fractions with varying degrees of mineral …

Abstract Around one-third of the world’s most carbon-rich ecosystems, mangrove forests, have already been destroyed in Thailand owing to coastal development and aquaculture. Improving these degraded areas through mangrove plantations can restore various coastal ecosystem services, including CO2 absorption and protection against …
