“…We observed rapid colonization of the soil fauna at the experimental sites in terms of both the number of individuals and classes with the composition dominated by acari and collembolas in all the treatments and references. This rapid colonization of newly created soil is consistent with other soil restoration or creation projects that also observed a rapid growth in soil fauna density [57,[92][93][94][95]. A density averaging around 10,000 indviduals/m 2 correspond to the colonisation rate observed on other technosols or brownfield sites after one year [57,96].…”

Brownfield technosol restoration represents a real opportunity to minimize land consumption, but it often requires intensive intervention and reconstruction, leading to soil donor site destruction and potential pollution. Using a former oil refinery brownfield site, this research compares the short-term (one year) impact of localized restoration methods, including soil surface scarification, organic matter addition, earthworm inoculation (locally and commercially sourced), on the soil fauna and vegetation properties. Vegetation rapidly covered the bare soil, but few significant impacts were observed in terms of the soil or vegetation structure. The initial positive impact of soil scarification on surface compaction quickly faded and earthworm inoculations did not seem to impact soil characteristics. Natural soil colonization by vegetation or fauna was the major driver in soil modification. The analysis of an intermediate reference showed a delay of multiple decades between vegetation, fauna density, and soil structure improvement, as well as the achievement of a soil of “good biological quality”. We conclude that the use of engineer species on brownfield soil in its actual form is not an early restoration step but should be tested in later steps (e.g., when organic matter content is sufficient). However, additional research is needed in engineer species selection and multi-compartment approaches. A better understanding of the impacts of natural colonization in the early stages of technosol restoration is also essential for restoration techniques’ improvement.

“…The reuse of mining waste together with other sectors, such as civil construction , has expanded the possibilities of its application. The use of technosols formed from waste recycling is a promising and sustainable alternative since the soil supports the biodiversity of organisms different to the natural environment [34]. The reuse of civil construction waste is still low, but its disposal can generate environmental, aesthetic, and public health problems, and overload municipal public cleaning systems.…”

Recovery of Degraded Areas through Technosols and Mineral Nanoparticles: A Review

et al. 2022

View full text Add to dashboard Cite

Anthropogenic sources such as urban and agricultural runoff, fossil fuel combustion, domestic and industrial wastewater effluents, and atmospheric deposition generate large volumes of nutrient-rich organic and inorganic waste. In their original state under subsurface conditions, they can be inert and thermodynamically stable, although when some of their components are exposed to surface conditions, they undergo great physicochemical and mineralogical transformations, thereby mobilizing their constituents, which often end up contaminating the environment. These residues can be used in the production of technosols as agricultural inputs and the recovery of degraded areas. Technosol is defined as artificial soil made from organic and inorganic waste, capable of performing environmental and productive functions in a similar way to natural ones. This study presents results of international research on the use of technosol to increase soil fertility levels and recover degraded areas in some countries. The conclusions of the various studies served to expand the field of applicability of this line of research on technosols in contaminated spaces. The review indicated very promising results that support the sustainability of our ecosystem, and the improvement achieved with this procedure in soils is comparable to the hybridization and selection of plants that agriculture has performed for centuries to obtain better harvests. Thus, the use of a technosol presupposes a much faster recovery without the need for any other type of intervention.

Collembola dispersion, selection, and biological interactions in urban ecosystems: a review

Most of the ecological predictions that are intended to be general have been made on the basis of observations of aerial organisms, ignoring subterranean organisms, which are subject to other -and complex -constraints compared from those present on the surface. Collembola, a soil fauna group, are good biological indicators of soil quality and could be used as model organisms in order to understand assembly rules of soil organisms in cities. Here we review available literature on soil Collembola conducted on 75 publications dealing with urban context.The major points are the following: (1) Soil properties and landscape characteristics influenced soil communities. The importance of landscape is also highlighted by the need of connectivity between urban green spaces in order to allow dispersion of Collembola.However, studies of Collembola communities in urban context are recent, offering little hindsight to understand their assembly. (2) A gap of references values, complexities by a lack of methods standardisation, is observable. Especially, knowledge on dispersion and biotic interactions are still too rare. (3) Moreover, studies on temporal aspect in order to understand better the colonisation processes are almost absent of the corpus.
