Soil GHG flux potentials and their microbiological mechanisms under urban forest and grassland

Soil Use and Management, Год журнала: 2025, Номер 41(1)

Опубликована: Янв. 1, 2025

Abstract Urban soils, both sources and sinks for greenhouse gases (GHGs) like carbon dioxide (CO 2 ), methane (CH 4 ) nitrous oxide (N O), significantly impact Earth's temperature. However, knowledge gaps remain regarding how variations in vegetation types, soil horizons seasons affect GHG fluxes, complicating predictions of soil‐atmosphere exchanges. Soil samples collected from the forest grassland Jinnan District, Tianjin, China, were used to determine physicochemical properties, extracellular enzyme activities (EEAs) fluxes. Meanwhile, structures functional genes microbial community analysed using metagenomic sequencing technology. Compared soil, flux potentials greater. Although not statistically significant, demonstrates lower CO potential CH compared soil. Notably, N O surpasses that Metagenomic analysis confirmed conclusion; relative abundance related fermentation, aerobic respiration fixation was higher The also exhibited a involved oxidation ( pomABC methanogenesis. shows levels source gene nirS sink nosZ than Combining three major GHGs, has larger global warming

Influence of soil organic carbon fractions on the soil priming effect under different vegetation restoration modes

Soil Use and Management, Год журнала: 2024, Номер 40(4)

Abstract The soil priming effect is a key mechanism influencing carbon (C) cycling processes between the forest organic (SOC) pool and atmosphere. Different vegetation restoration modes have different SOC compositions, it not clear whether such differences affect effect. Therefore, we selected from six typical Platycladus orientalis (PO), Pinus sylvestris (PS), Quercus acutissima (QA), shrub (SH) wasteland (WL) in rocky mountainous areas of northern China measured properties, microbial communities, necromass (MNC), fractions content decreased order PO (21.33 g kg −1 ), PS (22.00 QA (13.67 SH (13.33 ) WL (10.33 trends mineral‐associated (MAOC) fungal (FNC) were same as those content. was greater both forests shrublands than wastelands, with greatest occurring forests, where reached 159.91 mg CO 2 ‐C after 30 days incubation, which 1.4 times that WL. mainly determined by difference MAOC In addition, C/N ratio bacterial community diversity also indirectly affected MNC fractions. Overall, afforestation increased content, contribution mineral conservation, increasing This theoretical foundation supports enhancement sequestration capacity implementing various future.

Deep return of straw improves topsoil health and maize productivity more efficiently than shallow return

Soil Use and Management, Год журнала: 2024, Номер 40(4)

Опубликована: Окт. 1, 2024

Abstract Straw return is an important nature‐based solution to identify optimal management practices maintain cropland soil health and food security. However, there still limited information available regarding the impacts of different straw strategies on health, especially when considering a comprehensive assessment physical, chemical biological characteristics. Soil microorganisms are core key maintaining health. The present research aims determine impact depths index (SHI) crop productivity across layers. We conducted 3–year field experiment with four treatments: blank control no (NR), treatments shallow (SR), mulch (MR) deep (DR), application rate was 10,500 kg/ha. results showed that it microbial indicators dominated effects rather than organic carbon (SOC). Specifically, we found SR treatment exhibited highest extracellular enzyme activities both hydrolases oxidases in subsoil, peroxidase (PEO) activity 758.99 nmol/g/h. In addition, compared MR DR treatments, abundance symbiotroph fungi increased by 78.41% 54.38%, releasing more nutrients soil. Hence, SHI mainly increasing PEO NO 3 − –N content, significantly 25.59% 22.16% treatments. By contrast, greatly topsoil 43.33% 58.98% SM due enhanced biomass N (MBN) dissolved nitrogen (DON). had lowest bulk density (BD) which Bacteroidota but decreased Methylomirabilota abundance, thus resulting accumulation MBN. Moreover, led maize yield SHI. To conclude, effective method improve nutrient‐rich topsoil, while has much better effect subsoil. Our will provide theoretical paradigm for selecting strategies, crucial promoting productivity, achieving high yields, supporting sustainable agricultural development.
