“…Phosphorus was the only soil attribute that was significantly affected by the sludge doses, even though the regression models tested for each species did not allow good adjustments. This result could be explained by the fact that organic and humic substances in the sludge may have increased phosphate uptake by the plants, given that they can block phosphate adsorption sites of oxides and hydroxides of Fe and Al from the substrate -not only at the hole level but also for plot level (Sibanda and Young, 1986;Hua et al, 2008;Rocha et al, 2015). The increase in C concentration and stocks appears to modulate the phosphorus dynamic in this degraded area.…”

-Few studies have been carried out on aboveground (or belowground) and soil/substrate C accumulation in severely degraded areas, such as mined areas. The present study was developed in order to find a recovery strategy for a mined area and characterize its potential for C sequestration by planting two nitrogen-fixing Brazilian tree species (Mimosa caesalpiniifolia Benth and M. bimucronata (DC.) O. Kuntze). Sewage sludge was included in the experimental design. An experiment under randomized block condition and 2 x 5 factorial design with four replications were defined and carried out, in Rio de Janeiro State, Brazil. The treatments consisted of a combination of both tree species and five sewage sludge doses (0, 2.85; 5.70; ). M. caesalpiniifolia grows better (p<0.05) in reclaimed areas than M. bimucronata, even though neither the height nor the basal area of both species responded to the sludge application. Carbon stock in the tree trunks differ between species (27.3 and 14.3 Mg ha -1 , for M. caesalpinifolia and M. bimucronata, respectively), and was influenced by the doses of sewage sludge, whereas the soil carbon stock (0-10 cm) did not differ between species and doses (12.0 and 12.2 Mg ha -1 , for M. caesalpiniifolia and M. bimucronata, respectively). Soil fertility in the degraded site was found to be improved by legume trees six years after planting, with a small influence of the sewage sludge level. Mined areas recovered with legume trees can sequestrate significant amounts of C both in aboveground biomass and soil in a short period of time.Keywords: Soil carbon and nutrients accretion; Reclamation of soil; Aboveground biomass accumulation.

O presente estudo foi desenvolvido para encontrar uma estratégia de recuperação para uma área minerada e caracterizar o seu potencial de sequestro de C a partir do plantio de duas espécies de árvores brasileiras que fixam nitrogênio do ar (Mimosa caesalpiniifolia Benth e M. bimucronata (DC) O.

Assim, um experimento em delineamento em blocos ao acaso e esquema fatorial 2 x 5 e quatro repetições foi instalado no estado do Rio de Janeiro, Brasil. Os tratamentos consistiram em uma combinação de duas espécies arbóreas e cinco doses de lodo de esgoto

“…To assess whether forest restoration projects are feasible, monitoring of environmental quality, including soil analysis, and baseline assessment prior to monitoring are fundamental (Rocha et al ). Soil chemical indicators are important when considering soil capacity to maintain nutrient cycling, plant biomass, organic matter, and for sustaining forest production and sustainability (Schoenholtz et al ).…”

Consideration of soil quality indicators is fundamental for understanding and managing ecosystems. Despite the evidence regarding the importance of soil for provision of local and global ecosystem services, such as water regulation and carbon sequestration, soil remains an under-investigated and undermined aspect of the environment. Here we evaluate to what extent soil indicators are taken into account in restoration. We focused on the Brazilian Atlantic Forest, a highly fragmented biome and a global biodiversity hotspot. We conducted a systematic literature review and we showed that the majority (59%) of the studies on restoration did not consider any soil indicator. Studies that demonstrated the importance of soil indicators most commonly reported soil pH (71%, n = 44), followed by potassium content (66%, n = 41) and phosphorus (64.5%, n = 40), while the least reported indicator was water retention (6.5%, n = 4). Only 40% of the retrieved studies included information about reference sites or project baseline information. We complement our literature review with a case study on restoration in two areas of the Atlantic Forest. We found a relation between soil indicators such as soil organic matter, nitrogen, sodium and sand content, and aboveground indicators, confirming a necessity to include soil screening in restoration. Moreover, we found that prior to restoration none of these soil indicators were analyzed. This study highlights the gap that exists in soil data in restoration in studies on the Brazilian Atlantic Forest. We urge scientists and practitioners to include basic soil analysis to maximize the successful outcomes of restoration.

“…Na realização de estudos do solo a partir do uso de indicadores de qualidade é necessário adotar uma área de comparação, a qual deve se encontrar sob condições naturais ou pouco perturbadas (Rocha et al, 2015). Nos casos em que a área de estudo se encontra localizada em uma região próxima a fragmentos de mata, é recomendado o uso destes como área comparação (Lisboa et al ,2016).…”

Os lixões são caracterizados pela simples disposição final de resíduos sólidos sobre o solo sem qualquer medida de controle ambiental, impactando negativamente o meio em função da geração de gases, chorumes e outros subprodutos da degradação do material orgânico e inorgânico. Desde 2010 o Brasil tem buscado a desativação dos lixões. No entanto, o encerramento das atividades dos lixões resulta em áreas que sofreram degradação ambiental e necessitam de recuperação. O solo é considerado o principal desafio nos projetos de recuperação destas áreas, uma vez que seus atributos químicos, físicos e biológicos são fortemente afetados. O presente estudo teve como objetivo descrever sobre a utilização de indicadores de qualidade do solo, já estabelecida para situações agrícolas, em áreas de lixão desativado. Para tal, foi realizada uma revisão de literatura baseada em materiais científicos, legislações e documentos sobre gerenciamento dos resíduos sólidos publicadas sobre este assunto no período de 2012 a 2018. O emprego de indicadores de qualidade de solo em lixão desativado tem se tornado cada vez mais comum. No entanto, ainda são raros os estudos que combinam o emprego de indicadores físicos, químicos e biológicos na avaliação da condição ambiental destas áreas. A avaliação de áreas de lixão desativado por meio de um conjunto de indicadores torna-se essencial no processo de estabelecimento de projetos específicos de recuperação destas áreas. Evaluation of the quality of soil from disposal of disposal of land: a literature review A B S T R A C TThe dumps are characterized by simple final disposal of solid waste on the soil without any environmental control measure, impacting negatively the environment in function to the generation of gases, slurries and other by-products of organic and inorganic material degradation. Since 2010 Brazil has sought the disabling of drumps. However, the closure of the activities of the dumps results in areas that have suffered environmental degradation and need recovery. The soil is considered the main challenge in recovery projects in these areas, since their chemical, physical and biological attributes are strongly affected. This study aimed to describe the use of soil quality indicators for the evaluation of environmental condition in the disabled dump area. For this, a literature review was carried out based in scientific materials, legislation and documents about solid waste management published on this subject in the period from 2012 to 2018. The use of soil quality indicators in dump disabled area has become increasingly common. However, studies that combine physical, chemical and biological indicators in the assessment of the environmental condition of these areas are still rare. The assessment of disable dump areas by a set of indicators becomes essential in the process of establishing specific recovery projects in these areas.Keywords: Solid Waste Management, Final Disposal, Soil health.
