Abstract Anthropogenic land use modifications are causing severe degradation of terrestrial ecosystems, and multiple revegetation strategies emerging globally to counteract the loss plant richness productivity. While soil microorganisms essential for community dynamics, role microbial biodiversity in regulating changes productivity under different remains unknown. We used multitrophic co‐occurrence networks identify network modules strongly co‐occurring phylotypes along a 50‐year chronosequence agricultural abandonment afforestation. Soil within these was related nutrient cycling functions, (understorey layer afforestation), elucidating how associated with Plant increased simultaneously following both However, key taxa distinct coupled increases through regulation functions. Key involved nitrogen (N) correlated simultaneous increase abandonment. In contrast, those phosphorus (P) sulphur (S) were linked responses This reflects divergent mechanisms Synthesis. Our findings provide correlative evidence that is closely cessation management. taxa, specific each strategy, could serve as potential targets genomic cultivation‐based approaches degradation.

Impact of Exogenous Addition of Sulphur Powder on the Effectiveness of Kitchen Waste Compost Seedling Substrates

Polish Journal of Environmental Studies, Journal Year: 2024, Volume and Issue: unknown

The feasibility of using sulphur powder (SP) to improve physicochemical properties and promote growth cucumber seedlings in kitchen waste compost (KWC) was investigated cavity trays the greenhouse.The base substrate used consisted KWC, peat, rice husk perlite, respective ratios 15%:35%:40%:10% by volume.Treatments additions SP at rates 0 g (CK), 3 (T1), 6g (T2), 12 (T3) 24 (T4) per liter seedling (SS).The investigation showed that addition significantly reduced pH SS increased its EC values (p<0.05).The germination index (GI) seeds enhanced with T1 (p<0.05).However, other indicators (shoot belowground indices) maximum T2.Levels plant nutrients (N, P, K) organic matter this reflected a trend uptake order T2>T1>CK>T3>T4, while levels substances T3 T4 were consistent deleterious effects excess SP.Fluorescence analysis Fusarium spp. significant reductions copy numbers fungi (p<0.05) as sulfur decrease T4>T3>T2>T1>CK.For composition for study, T2 gave best results establishment seedlings.Other combinations must be evaluated determine appropriate amounts components under specific circumstances.
