Impacts of the Ecosystem Transformation in Red Jujube Commercial Forests on the Soil Organic Carbon Sources and Stability in the Lvliang Mountains

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Soil organic carbon (SOC) stabilization is vital for the mitigation of global climate change and retention soil stocks. The Loess Plateau a crucial ecological zone in China even worldwide major ecosystem protection. However, Plateau, there are knowledge gaps about response SOC sources to different transitions jujube economic forests. Therefore, our study used clean‐cultivated orchards as control (CK) selected five main transformation models abandoned on Lvliang Mountain: farmland (AF), replanted with Astragalus‐Bupleurum (AB), alfalfa (AL), Chinese pine (CP), arborvitae (PO). properties, physical fractions their correlations 0‐ 20‐cm layer at each sample site were analyzed. results show that significantly increased by affecting plant‐ microbe‐derived altering its components. Different treatments have varying impacts content. lignin phenol (VSC) content soils was greater than CK had following ranking: CP > AL PO AF AB ( p < 0.05). also total amino sugar (TAS) content, microbial residue (MRC), contribution carbon. Additionally, it promoted accumulation particulate (POC) mineral‐associated (MAOC) positively impacted stability.

Microbial Necromass Nitrogen Accumulation and Its Response to Soil Multifunctionality Following Plantation Restoration in a Subtropical Karst Region

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

ABSTRACT Microbial necromass nitrogen (MNN) is increasingly recognized as a major source of soil N, playing crucial role in N sequestration and sustaining balance. However, quantitative data on the contribution MNN to total its relationship with multifunctionality (SMF) karst plantation ecosystems remain lacking. In this study, (measured via amino sugar analysis) SMF (calculated using mean value method) were determined across five plantations unafforested land (control) Wuling Mountains subtropical China. The content ranged from 1.02 1.67 g kg −1 , contributing 53.8% 75.4% Cinnamomum camphora pure forest exhibiting highest values among all stand types control. afforestation enhanced nutrient provision, microbial activity, biomass, increasing by 54% compared functional parameters generally higher organic horizon than topsoil subsoil, was greater subsoil. Enzyme stoichiometry ratios indicated that P limitation prevalent both control soils, positively correlated C/P N/P ( p < 0.001).

Soil fungal community and co-occurrence network patterns at different successional stages of black locust coppice stands

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: March 18, 2025

Black locust (Robinia pseudoacacia L.) plantations transition from seedling to multi-generation coppice systems, leading declines in productivity and biodiversity. However, the structural functional reorganization of soil fungal communities during this remains poorly understood. This study aimed characterize community dynamics across successional stages black stands assess their implications for health ecosystem resilience. Soil three (first-generation forest, first- second-generation forests) were analyzed over one year using ITS high-throughput sequencing. We evaluated diversity, guild composition, co-occurrence networks, integrating statistical analyses (PERMANOVA, ANOSIM, FUNGuild) network theory seasonal shifts. Fungal richness diversity remained stable stand types seasons. these factors dramatically altered structure. Shifts composition observed stands: Ascomycota dominance decreased (72.9 57.9%), while Basidiomycota increased (6.5 11.6%). Significant changes relative abundance certain guilds by both conversion variation (p < 0.05). overall was only significantly affected variation, rather than > Furthermore, saprotrophic fungi dominated autumn/winter (66.49-76.01%), whereas symbiotic peaked spring (up 7.27%). As forests seeding stands, percentage negative edges, average degree, modularity networks all gradually decreased. Those suggested that connectivity between species, formed less organized structure, homogeneity function among microbial communities, reduced ecological functionality, resistance environmental changes. Seasonal temperature fluctuations further modulated complexity, with summer samples showing heightened edge density but cooperation. Our findings suggest can shift structure assembly, favoring reducing stability. These shifts signal progressive nutrient depletion homogenization, potentially compromising highlight fungi's role cycling, saprotrophs driving litter decomposition colder months. understanding forest management practices must prioritise preservation early stages. is vital support diverse complex ensure stability, functionality communities.
