Environmental recovery from deactivated open dumping using direct seeding of native and short life-cycle species
Year: 2025
Type: article
Abstract: The present study aimed to evaluate the efficacy of recovering a solid waste deposit area, deactivated 17 years ago, using the no-seeding of native species of the Brazilian savannah and cover. We conducted the study between 2016 and 2018 in 1 ha with the dominance of exotic grasses Urochloa decumbes and Melinis minutiflora. We delimited four environments of 11m x 29m (319 m2) with ten plots of 5 x 5m (25m²). The environments showed low concentrations of macronutrients and organic matter (OM). This study is relevant for scientific advancement and the practical resolution of socio-environmental problems, especially in a context where inadequate solid waste management continues to be a growing challenge. We found a lower establishment rate and survival percentage for Cerrado species, 2400 plants.ha-1 (3.26%) and 71300 plants. ha-1 (96.74%) of short life-cycle species. The most satisfactory procedure was the treatment that used density II + sowing in soil without manure. This research fills the gap in the literature on the recovery of solid waste deposits. This study's results can help manage and recover areas similar to this in other regions of the country.
