Agromining describes the technique of growing plants to "mine" metals present in naturally enriched or contaminated soils. This technique comprises a series of processes including improvement of soil quality and production of biomass in order to obtain metals from the ash of harvested hyperaccumula-tors, which can be considered bio-ore. The aim of...
Grasslands play a crucial role in European agriculture and ecology, but are often underutilized due to low-value end-products. The utilisation of late-harvest grass for biochar and heat generation on farm-level is being studied as a potential negative emissions technology. Technical (energy provision and carbon sink), economic (cost vs. benefit), p...
Purpose
Rhizosphere processes are known to modify uptake of elements from soil, but limited information is available for hyperaccumulators. We investigated labile Ni fractions and their kinetics of replenishment in the rhizospheres of the Ni-hyperaccumulator Odontarrhena serpyliffolia, the Ni-excluder Holcus lanatus and in bulk soils collected at t...
The diversity of cultivable bacteria associated with plants from phytomanaged soils with mixed trace metal (TM) and polycyclic aromatic hydrocarbon (PAH) contamination in Pierrelaye (France) was evaluated. The emphasis was on the cultivable bacterial community since the overall objective is to obtain inoculants to improve the remediation of this ty...
The effects of climate change threaten food security by affecting the production and quality of crops that are part of the world's food base, such as wheat. The crop-tree association can act as a tool to mitigate and adapt to climate change, and it is important to analyze the influence of the shade cast by the tree canopy on the yield of important...
Integrating woody perennials and agricultural crops combined is a centuries-old practice, nowadays called agroforestry. Because agroforestry is being promoted by public administrations, it is essential to obtain scientific knowledge about the effect of different factors (e.g. tree shade) on crop characteristics. In this study, the effects of light...
Rural depopulation as well as the intensification of farming systems in southern Europe have led to important changes in landscape and the ecosystem services they provide. Indoors livestock production is translated into a reduction or absence of grazing which ends up with a rapid expansion of bushes and extensive processes of natural forestation. T...
Climate change affects temperate areas by increasing the risk of suffering extreme climatic events and sharping major problematics. Moreover, climate change and its related effects jeopardize water and food supply. Rural areas are key for sustainable development and provide socio-economics advantages, but it also exists a downside on key aspects su...
The study of root-associated microbial communities is important to understand the natural processes involved in plant recolonisation at degraded areas. Root associated bacterial and fungal communities of woody species colonising a red gypsum landfill (a metal-enriched environment) were characterised through metabarcoding. Among trees naturally grow...
La réhabilitation des sites de stockage de déchets industriels est un enjeu majeur pour limiter l’impact des résidus miniers sur l’environnement. Cette étude a caractérisé la communauté bactérienne de sols végétalisés et non végétalisés d’une décharge de gypse rouge résultant de l’extraction industrielle du titane. L’approche traditionnelle par iso...
The successful restoration of well-engineered tailings storage facilities is needed to avoid mine tailings problems. This study characterized the bacterial communities from vegetated and non-vegetated soils from a red gypsum landfill resulting from the industrial extraction of titanium. A set of 275 bacteria was isolated from vegetated soil and non...
Industrial waste dumps are rarely colonized by vegetation after they have been abandoned, indicating biological infertility. Revegetation of industrial tailings dumps is thus necessary to prevent wind erosion, metal leaching and has been shown to restore soil functions and ecosystem services. However, little is known about the microbial colonizatio...
Several phytotechnologies have been developed for the treatment of soils contaminated with organic compounds and/or trace elements, or for a sustainable exploitation of metalliferous soils inadequate for conventional agroforestry. These plant-based techniques can allow for a sustainable and profitable management of such sites, within the concept of...
Soil contamination by trace elements (TEs) is still one of the major environmental problems on a global scale. Only in Europe, it is estimated that the number of potentially contaminated sites exceeds 2.5 million and near 35% of them are affected by TEs. Multi-contamination events and the high potential toxicity and persistence of these elements in...
We evaluated the effect of compost amendment and/or bacterial inoculants on the growth and metal accumulation of Salix caprea (clone BOKU 01 AT-004) and Nicotiana tabacum (in vitro-bred clone NBCu10-8). Soil was collected from an abandoned Pb/Zn mine and rhizobacterial inoculants were previously isolated from plants growing at the same site. Plants...
Plants interact closely with microbes and these can enhance plant growth and health by increasing nutrient uptake and improving plant resistance to pathogens and stress. Plant-associated microorganisms are commonly used as ‘biofertilisers’ in agriculture but their incorporation into phytoremediation systems to improve plant establishment and growth...
(Aided) phytostabilisation has been proposed as a suitable technique to decrease the environmental risks associated with metal(loid)-enriched mine tailings. Field scale evaluations are needed for demonstrating their effectiveness in the medium- to long-term. A field trial was implemented in spring 2011 in Cu-rich mine tailings in the NW of Spain. T...
Ni phytomining is a promising technology for Ni recovery from low-grade ores such as ultramafic soils. Metal-hyperaccumulators are good candidates for phytomining due to their extraordinary capacity for Ni accumulation. However, many of these plants produce a low biomass, which makes the use of agronomic techniques for improving their growth necess...
In this study different bacterial inoculation methods were tested for tobacco plants growing in a mine-soil contaminated with Pb, Zn and Cd. The inoculation methods evaluated were: seed inoculation, soil inoculation, dual soil inoculation event and seed+soil inoculation. Each inoculum was added at two bacterial densities (10(6) CFUs mL(-1) and 10(8...
Aim: Plant-associated bacteria can improve phytoextraction by increasing plant growth and/or metal uptake. This study aimed to characterise the culturable rhizobacterial community associated with two Ni-hyperaccumulators and to obtain a collection of isolates for application in Ni phytomining. Methods: Non-vegetated and rhizosphere soil samples wer...
ABSTRACT The last few decades have seen the rise of Gentle soil Remediation Options (GRO), which notably include in situ contaminant stabilization ("inactivation") and plant-based (generally termed "phytoremediation") options. For trace element (TE)-contaminated sites, GRO aim to either decrease their labile pool and/or total content in the soil, t...
We present the efficiency of phytomanagement solutions implemented at the field plot level in the European network EU FP7 GREENLAND, coupling the management of trace element-contaminated soils by phytoremediation options, the production of plant biomass for non-food use, and ecological restoration of ecosystem services. The trials evaluate the perf...
Metals can be stabilized by soil amendments that increase metals adsorption or alter their chemical forms. Such treatments may limit the risk related to the contamination through reduction of metal transfer to the food chain (reduction of metal uptake by plants and its availability to soil organisms) and metals migration within the environment. The...
Bacterial strains were isolated from the rhizosphere of three populations of the Ni-hyperaccumulator Alyssum serpyllifolium subsp. lusitanicum (A. pintodasilvae; M, S, and L), one population of Ni-hyperaccumulator A. serpyllifolium subsp. malacitanum (A. malacitanum; SB), and one population of the non-hyperaccumulator A. serpyllifolium subsp. serpy...
