Role of Plants and Urban Soils in Carbon Stock: Status, Modulators, and Sustainable Management Practices

Plants, Journal Year: 2025, Volume and Issue: 14(4), P. 546 - 546

Published: Feb. 10, 2025

Urban soils are vital components of urban ecosystems, significantly influenced by anthropogenic activities and environmental factors. Despite misconceptions about their quality, play a pivotal role in carbon (C) cycling storage, impacting global emissions sequestration. However, challenges such as soil contamination, land use changes, expansion pose significant threats to quality C storage capacity. Over the last two decades, there has been an increasing interest potential part climate change mitigation strategies. In this review, bibliometric analysis covering twenty years (2004-2024) was performed offer insights into research trends, mainly Mediterranean region. This paper also identifies gaps proposes essential solutions for mitigating negative impacts urbanization on biodiversity functions. Key modulators, including plants, microbes, features, highlighted dynamics, emphasizing importance effective vegetation management enhance sequestration ecosystem services. Strategies reintroducing nature areas applying organic amendments promising improving microbial diversity. Further awareness maximize effectiveness these strategies, ensuring sustainable resilience.

Microplastic Transport by Overland Flow: Effects of Soil Texture and Slope Gradient Under Simulated Semi-Arid Conditions

Soil Systems, Journal Year: 2025, Volume and Issue: 9(2), P. 40 - 40

Published: April 29, 2025

Microplastic pollution in soils and surface waters is a growing environmental concern, yet the mechanisms governing transport by overland flow remain unclear. This study investigated influence of soil texture slope gradient on movement microplastics with different shapes polymer compositions under simulated rainfall typical agricultural conditions semi-arid climate. Small flumes were subjected to controlled simulations replicating rain patterns, microplastic was quantified using collection flasks. The results indicated that neither nor significantly affected total transport. However, fibres exhibited greater retention compared other shapes. Polymer composition did not play major role mobility, except for polystyrene pellets, which transported more readily than polyethylene pellets. Field observations history sludge application confirmed predominance topsoil, reinforcing tendency this shape resist mobilisation. These findings suggest runoff primarily governed particle buoyancy rather properties or inclination. Future research should explore roles size, intensity, organic matter content mobility natural field conditions.

Mitigating the detrimental impacts of low- and high-density polyethylene microplastics using a novel microbial consortium on a soil-plant system: Insights and interactions

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 283, P. 116805 - 116805

Published: Aug. 3, 2024

The accumulation of polyethylene microplastics (PE-MPs) in soil has raised considerable concerns; however, the effects their persistence and mitigation on agroecosystems have not been explored. This study aimed to assess detrimental PE-MPs a soil-plant system evaluate using novel microbial consortium (MC). We incorporated low-density (LDPE) high-density (HDPE) at two different concentrations, along with control (0 %, 1 2 % w/w) into sandy loam for duration 135 days. samples were also treated MC incubated comprised three bacterial strains (Ralstonia pickettii (MW290933) strain SHAn2, Pseudomonas putida ShA, Lysinibacillus xylanilyticus XDB9 (T) S7-10F), fungal (Aspergillus niger F1-16S). Sunflowers subsequently cultivated, physiological growth parameters measured. results showed that adding LDPE significantly decreased pH by 1.06 units compared control. Moreover, HDPE resulted more significant decrease electrical conductivity (EC) relative A dose-dependent increase dissolved organic carbon (DOC) was observed, highest DOC found LDPE. addition higher dosages reduced bulk density (BD) than HDPE. increased water drop penetration time (WDPT) but mean weight diameter aggregates (MWD) water-stable (WSA) revealed levels enhanced basal respiration (BR) biomass (MBC). interaction MP percentages considerably pH, EC, BD, WDPT DOC, MWD, WSA, BR, MBC. Regarding plant growth, incorporating responses sunflower: chlorophyll content (Chl; -15.2 %), Fv/Fm ratio (-25.3 shoot dry (ShD; -31.3 root (RD; -40 leaf area (LA; -38.4 stem (StemD; -25 %) control; ameliorated harmful investigated responses.
