Soil multifunctionality is essential for the enhancement of soil carbon sequestration, but disturbances such as thinning practices can influence microbial activity and cycling. Microbial residues, particularly residue (MRC), are important contributors to organic (SOC), effects intensity on MRC accumulation remain poorly understood. This study evaluated impact four treatments-control (CK, 0%), light-intensity (LIT, 20%), medium-intensity (MIT, 30%), high-intensity (HIT, 45%)-on in Chinese fir plantations five years after thinning. nutrient provision, biomass, enzyme activity, were assessed. The results showed that significantly affected provision with MIT HIT showing higher levels than CK LIT. Specifically, MIT's HIT's total increased by 0.04 0.15 compared CK. Enzyme was highest LIT (+0.89), followed (+0.07), a decline (-0.84). including bacterial PLFAs (B-PLFAs), fungal (F-PLFAs), biomass (MBC), nitrogen (MBN), MIT, lowest HIT, 0.13 increase (MRC) positively correlated (TN), available (AN), easily oxidized (EOC). content 0-20 cm layer observed (10.46 11.66 g/kg, respectively), while lower, reduced 24% 12%, respectively. These findings highlight significant role Medium-intensity 30%) identified most effective approach promoting enhancing cycling forest soils, making it an optimal management aimed at increasing sequestration.

Short-term impacts of soil enzyme activity in rhizosphere and bulk soils by forest gap size of a Platycladus orientalis plantation

Forest Systems, Journal Year: 2025, Volume and Issue: 34(1), P. 20913 - 20913

Published: May 5, 2025

Aim of study: We investigated how changes in forest gap size influence soil enzyme activities both the rhizosphere and bulk soils, mediated by effects (RE). Area Xuzhou, Jiangsu Province, China. Material methods: The study was conducted a 46-year-old Platycladus orientalis (L.) Franco, 1950 plantation Xuzhou its aim accomplished sampling one year after gaps establishment, from three levels sizes: small (S, with radius 4 m), medium (M, 8 large (L, 12 as well control plots (CK, without any gaps). Soil activities, including peroxidase (PER), dehydrogenase (DEH), urease (URE), invertase (INV), were quantified. Main results: Gap season strongly affected RE on DEH URE. interaction size, location significantly DEH, URE, INV. Enzyme soils more sensitive to nutrient availability than microbial biomass played crucial role modulating activity. Furthermore, L S exerted an activity, exhibiting most extensive impact. Research highlights: This observed that activity did not increase enlargement size. However, gaps, impact range extensive.
