Unraveling the Impact of Diverse Vegetative Covers on Soil Carbon Fractions

Sustainability, Journal Year: 2025, Volume and Issue: 17(3), P. 1080 - 1080

Published: Jan. 28, 2025

Evaluating SOC lability is crucial for sustainable agriculture policies and environmental quality. This study assessed the impact of well-stocked forest cover on pools compared to shrubby soil. Geo-referenced soils under Red pine (Pinus brutia), Black nigra), Cedar (Cedrus libani), Fir (Abies cilicia), Juniper (Juniperus excelsa), Oak (Quercus L.), Carob (Ceratonia siliqua), degraded shrubs were collected from a depth 0 30 cm in Seyhan River Basin, Mediterranean Turkey. The analysis soil organic carbon (SOC), AC (active carbon), PC (passive carbon) analyzed understand management across diverse vegetation types. forests have highest (27.98 g/kg) (27.35 g/kg), followed by (SOC: 27.64 g/kg, PC: 27.05 26.44 25.85 g/kg). Shrubby areas lowest (4.06 (3.61 had CLI (1.16), suggesting relatively higher proportion labile than other forests. CPI indicates greater storage capacity (1.09) shrublands (0.18), with also having CMI (0.83). findings emphasize critical role forests, especially sequestration climate change mitigation within Basin

Thinning Modulates the Soil Organic Carbon Pool, Soil Enzyme Activity, and Stoichiometric Characteristics in Plantations in a Hilly Zone

Forests, Journal Year: 2024, Volume and Issue: 15(11), P. 2038 - 2038

Published: Nov. 19, 2024

Thinning, a core forest management measure, is implemented to adjust stand density and affect soil biogeochemical processes by changing biotic abiotic properties. However, the responses of organic carbon (SOC), enzyme activity (EEA), stoichiometry (EES) in plantations hilly zones thinning have received little attention. To test hypothesis that has regulatory effects on SOC pool, EEA, EES characteristics, field sampling indoor analysis were conducted 9 years after thinning. Thinning significantly influenced properties, especially topsoil, greater mineral-associated (MAOC) contents observed high-density treatment. The EEAs topsoil tended increase with increasing density. SOC, MAOC, C phosphorus (C:P) had greatest influence EESs. Microbial metabolic limitations change from nitrogen fractions, available nutrients, elemental drove microbial positively correlated β-glucosidase, stoichiometry, EES. This study deepens our understanding EEAs, nutrient dynamics under practices elucidates how tending measures processes, thereby providing ideas for developing strategies mitigate adverse impacts human interventions.

N-fixing tree species promote the chemical stability of soil organic carbon in subtropical plantations through increasing the relative contribution of plant-derived lipids

Forest Ecosystems, Journal Year: 2024, Volume and Issue: 11, P. 100232 - 100232

Published: Jan. 1, 2024

Biodiversity experiments have shown that soil organic carbon (SOC) is not only a function of plant diversity, but also closely related to the nitrogen(N)-fixing plants. However, effect N-fixing trees on SOC chemical stability still little known, especially with compounding effects tree species diversity. An experimental field manipulation was established in subtropical plantations southern China explore impacts richness (i.e., one, two, four and six species) with/without stability, as indicated by ratio easily oxidized (EOC/SOC). Plant-derived C components terms hydrolysable lipids lignin phenols were isolated from soils for evaluating their relative contributions stability. The results showed rather than had significant EOC/SOC. Hydrolysable negatively correlated EOC/SOC, while contributed more EOC/SOC phenols, occurrence trees. presence led an increase N availability decrease fungal abundance, promoting selective retention certain key lipids, thus enhancing These findings underpin crucial role shaping therefore, preferential selection mixed appropriate silvicultural strategy improve plantations.
