The use of plastic agricultural mulching films presents a “double-edged sword”: while these enhance crop yields, they also lead to the accumulation film residues in soil, creating new pollutants (microplastics). Our understanding “plastisphere”, niche formed by where unique microbial communities and soil conditions converge remains limited. This is particularly true for protists, which are recognized as key determinants health. Therefore, this study simulated field experiment analyze effects long-term on structure protist rhizosphere, bulk plastisphere oilseed rape well their nutrients. results revealed that residual underwent significant structural chemical degradations. Protist diversity co-occurrence network complexity were markedly reduced soils. In addition, moisture content, inorganic nitrogen available phosphorus levels declined, leading deficiencies Functional shifts consumer protists phototrophs along with weakened interactions, have been identified drivers impaired nutrient turnover. underscores critical role maintaining cycling highlights profound adverse ecosystems. These findings provide valuable insights into mitigating residue preserve fertility ensure sustainable productivity.

Root metabolite secretion plays a critical role in increasing nutrient acquisition, allelopathy, and shaping the root-associated microbiome. While much research has explored ecological functions of root exudates, their relevance to horticultural practices, particularly soilless cultivation, remains underexplored. Steering exudation could help growers enhance effectiveness plant growth-promoting bacteria. This review summarizes current knowledge on systems, examining its process discussing environmental influences context cultivation. Plants systems exhibit higher total carbon rates compared those natural soils, with profiles varying across species. decreases age, most adaptations occurring during early growth stages. Several factors unique affect exudation. For instance, availability major impact Light intensity reduces rates, light quality species- environment-dependent manner. Elevated CO2 temperature increase Factors related hydroponic solution growing media composition remain insufficiently understood, necessitating further research.
