Microplastic (MP) can significantly affect soil behaviour and the ecosystem. This paper presents an experimental study to investigate effects of MP contamination leachate exposure on desiccation cracks, hydraulic conductivity, water retention properties natural black clay. The was from a landfill in Australia. clay incorporated with up 2.0% MPs by weight (w/w) diverse dimensions mixed water/leachate. measured include saturated conductivity (k

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.
