Phytomanagement with grassy species, compost and dolomitic limestone rehabilitates a meadow at a wood preservation site

Brownfield surface is expanding in Europe, but as often abandoned or underused, these areas become refuge for microbial, faunal and floral biodiversity. However, brownfield sites are generally contaminated, likely posing severe environmental risks. At a former wood preservation site contaminated with Cu, we evaluated the efficiency of compost dolomitic limestone incorporation into soil, followed by revegetation Cu-tolerant grassy species, phytomanagement option to increase vegetation cover plant diversity while reducing pollutant linkages. 7 years enhanced natural through improvement soil physicochemical properties, particularly compost-based amendments. The increased Cu solubility; however, no increment availability reduction Cu-induced phytotoxicity were observed compost. improved nutrient mitigation compost-amended soils facilitated over growth beneficial colonists, including leguminous which can potentially promote essential functions. Soil treatments did not affect uptake translocation plants shoot levels indicated risk food chain. Overall, long-term combining an initial amendment cultivation populations ameliorate such Cu-contaminated soils, mitigating risks induced excess, ultimately allowing development meadow that provide ecological economic benefits terms ecosystem services.
