ABSTRACT Extensive usage of agricultural plastic film correspondingly leads to excessive residues microplastics (MPs). MP accumulation alters soil hydraulic properties and water flow. However, little is known about the combined effects concentration particle size on hydrological properties, a numerical approach for modelling infiltrated flow has not been well developed. Hence, we determined affected by established model suitable MP‐contaminated soils. Quantitative findings indicated that saturated conductivity soil–MP mixture was 10.8%–50.0% smaller than pure soil, which decreased increased with increase in size, respectively. The always had significant influences conductivity; contrast, generated under condition small size. Besides, higher or MPs led weaker water‐holding capacity, residual content 0.6% – 41.5% 0.2% 11.6%, Furthermore, presence inhibited infiltration, wetting front migration rate cumulative infiltration 7.1% 29.4% 4.7% 21.7%, respectively, Correlation analysis negatively correlated saturated/residual moisture, infiltration; addition, conductivity, compared (15.63%), (46.28%) played major role response movement changes external environment.

Abstract Plant invasions pose a major threat to terrestrial biodiversity, and microplastic pollution in soil could exacerbate this problem. Seed germination, crucial stage for plants, can be affected by microplastics through both physical interference of plastic particles chemical leaching from additives. We conducted greenhouse experiment using native invasive plant species European grasslands, evaluated individual combined effects additives on germination parameters. found that primarily seed as agents, while these exerted comparatively lesser impact. Particles negatively all species. Germination velocity, synchrony total decreased ~30%, ~11% ~11%, respectively, soils containing compared those without. Certain were For Achillea millefolium Dactylis glomerata , velocity ~26% ~7%, ~21% with than without them. Plastic may have blocked pores inhibited hypocotyl radicle growth, toxic compounds disrupted key processes. By contrast, generally did not affect species, suggesting the negative experienced natives, whether or chemical, counteracted resulting novel conditions created microplastics, which include amelioration properties such increased porosity aeration, potential positive plant–soil feedbacks. Invasive profit windows variable resource availability, germination. Synthesis . promote invasion affecting having neutral The delayed natives due poses threat, leading competitive disadvantages, reduced reproductive success vulnerability Microplastic appears favour over during early stages highlighting effect ecosystems more severe previously thought.
