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. A two‐dimensional proposed considering Richards equation parameters mixture, based finite element theory further employed validated through comparing experimental observations simulations, high accuracy simulating process MP‐contained Our elucidate influence confirm potential using simulations predict

As a perennial plant, the nutrient supply for tea bushes is predominantly dependent on soil. Yunnan plantations exhibit significant topographic slope variations, yet combined impact of positions soil chemistry and microbial communities remains unexplored. This study investigated chemical properties community structures across three distinct areas within single plantation. The results showed that contents organic matter (OM), total nitrogen (TN), available nutrients (AN) at top (TS) were significantly higher than those foot (FS) (p < 0.001), while cation exchange capacity (CEC) potassium (TK) reached peak levels in middle (MS), with FS having lowest levels. Redundancy analysis (RDA) indicated bacterial primarily influenced by TK, magnesium (Mg), CEC, phosphorus (TP), pH, whereas fungal mainly regulated Mg, highlighting role shaping diversity distribution. Bacterial composition no slope-related differences, but varied notably family/genus MS exhibited highest network complexity, suggesting stronger species interactions. metabolic functions trophic modes conserved regions, indicating functional stability independent structural changes. reveals slope-driven soil-microbial dynamics plantations, offering insights into assembly adaptation under gradients. These findings support precision fertilization, ecological conservation, sustainable management plantations.

Microplastics (MPs) in agricultural soils pose risks to human health their potential accumulation along the food chain, and characteristics require further understanding implement targeted measures. This study investigated MP typical mulching from different farming scales Sichuan Province, which is one of China’s key regions, it also innovatively measured ecological risk by incorporating size into assessments. The sites showed average microplastic abundances 19696.81 ± 13226.89, these were dominated small-sized ethylene–propylene copolymer (E/P), polypropylene (PP), polyethylene (PE) particles yellow-to-brown black-to-shallow-gray soil. Size-considered evaluation suggested that most at a high level risk. It was found pollution varies with scales. Larger-scale primarily received MPs plastic mulching, while smaller-scale likely affected range non-agricultural sources. assessment significant contributions polyamide (PA) polyphenylene sulfide (PPS). These results indicate environmental management strategies should tailor source control measures according prioritize high-risk polymers, as well evaluations include “size” “pollution load” “chemical composition” better reflect impact on ecosystems.
