Intensive vegetable production under plastic mulch: A field study on soil plastic and pesticide residues and their effects on the soil microbiome

Oxytetracycline Increases the Residual Risk of Imidacloprid in Radish (Raphanus sativus) and Disturbs the Plant-Rhizosphere Microbiome Holobiont Homeostasis

“…With OTC exposure, the abundance of Firmicutes, Actinobacteria, and Elusimicrobia were increased and Aminicenantes and Euryarchaeota were decreased, as shown in Figure B. Beriot et al found that pesticide residues in agricultural soil and their effects on microbial communities may impact crop production . The changes of Firmicutes, Acidobacteria, and Verrucomicrobia could regulate nitrogen acquisition of vegetables …”

“…Beriot et al found that pesticide residues in agricultural soil and their effects on microbial communities may impact crop production. 41 The changes of Firmicutes, Acidobacteria, and Verrucomicrobia could regulate nitrogen acquisition of vegetables. 42 The comparison between the single-pollution and combined-pollution groups is shown in Figure 4C,D.…”

Exploring the potential of earthworms to reduce microplastic pollution in soils

“…A survey on farmlands in the US with 23 years of biosolid application history showed that the MPs contents were 360-500 items kg -1 soil (Adhikari et al, 2024). In another study, soils from vegetable farms in southeast Spain were found to contain ∼2×10 3 items kg −1 (equivalent to ∼60 cm 2 kg −1 ) MPs (Beriot et al, 2023). A study involving 19 provinces in China showed that the abundances of MPs increased over time in the locations where plastic mulching was continuously employed, with concentrations of 80.3 ± 49.3, 308 ± 138.1, and 1075.6 ± 346.8 items kg −1 soil in fields with 5, 15, and 24 years of continuous mulching, respectively (Huang et al, 2020).…”

“…Varying the polymer types (non-biodegradable plastics, biodegradable plastics), particle sizes (nanoplastics, microplastics), soil types, dosages (environmental concentrations, high concentrations), and incubation time (short-term, long-term), among other parameters, researchers have mostly reported that MPs can exert influence on soil microbiome in different environments, e.g., crop rhizospheres (Qi et al, 2020;, forest soil and vegetable farmlands (Beriot et al, 2023). A meta-analysis based on existing literature suggested that soil biota exposed to MPs under high concentrations and for long periods are more likely to receive negative effects on the structure and function (Liu et al, 2023).…”
