Effects of microplastics, vermicompost and zeolite on microflora of soils with different physical properties
AI summary Read the abstract
Researchers studied the effects of microplastics, vermicompost, and zeolite as additives on soil microflora and physical conditions in two soil varieties including Vertic Phaeozem clay, conducting laboratory experiments to compare how these inorganic, organic, and mineral amendments alter microbial communities.
The effect of additives of different composition and origin - non-organic (microplastics), organic (vermicompost) and mineral (zeolite) on microflora and soil physical conditions of two soil varieties was studied. A laboratory experiment was performed on soil samples, taken from the surface (0-20 cm) soil layer of Vertic Phaeozem (clay textural class), from the experimental field Gorni Lozen under grassland and of Haplic Cambisol (loam textural class), from the experimental station of potatoes Samokov, cultivated land. The concentrations of the additives were 10% by mass of the sample. The amount of main groups of soil microorganisms was determined - ammonifying and cellulolytic microorganisms, mineral nitrogen-utilizing bacteria, actinomycetes and microscopic fungi. The changes of water retention properties of the studied mixtures were analyzed. It was found that the distribution of soil microorganisms was influenced in a different way by the applied additives in the studied soils.

Interaction effects and mechanisms of microorganisms and microplastics in soil environment
AI summary Read the abstract
This review examines how microplastics and soil microorganisms interact: microplastics disrupt soil structure, reduce water retention, and impede plant root growth, while certain bacteria and fungi can colonize and partially degrade plastic particles through a multi-step process involving colonization, fragmentation, assimilation, and mineralization. Different polymer types (PE, PP, PS, PVC, PET) attract different microbial communities, and factors like temperature, moisture, and plastic additives affect degradation rates. Understanding these interactions is key to assessing long-term soil health impacts and developing microbial strategies to reduce plastic accumulation in agricultural soils.
