“…Soil was then filled in a tall slender jar (like a quart jar) 1 4 full. Water was added until the jar was 3 4 full and a teaspoon of powdered, non-foaming dishwasher detergent was added. The jar was sealed with a tight-fitting lid, shaken manually for 10 to 15 min to break the soil aggregates, and then left undisturbed.…”

“…Thus, sustainable land use and protection of soils play a key role in food, climate, and human security [2]. Fertile soils are a non-renewable resource by human time spans as their formation and renewal could take hundreds, if not thousands of years [3]. For this reason, the human management of soil resources will have wide-ranging consequences on human security for generations to come [4].…”

A heavily degraded hardé area in the community of Gawel (Extreme Nord) was rehabilitated with a ReviTec approach. To evaluate the efficiency of introduced plants for rehabilitation, the site was monitored with the BioSoilPlot experiment over two years during the dry and rainy seasons (January 2018/2019, June 2018/2019, respectively). ReviTec was applied to accelerate ecological succession and improve the establishment of vegetation on these degradation-prone sites (Gawel 1 and Gawel 2). Growth volume, height and percentage cover of the herbaceous plants and soil physical and chemical parameters were assessed. Growth volume increased in both sites between 2018 and 2019 with Pennisetum pedicellatum exhibiting the highest values (Gawel 1: 3.41 dm3/m2 and 3.50 dm3/m2; Gawel 2: 3.47 dm3/m2 and 3.62 dm3/m2). Bunds were suitable for herbaceous growth, Sesbania sesban having the highest growth height (Gawel 1: 1.91 cm and 1.95 cm; Gawel 2: 1.95 cm and 1.97 cm) and Pennisetum pedicellatum the best percentage cover (Gawel 1: 53% and 58.33%; Gawel 2: 40.67% and 56.67%). Soil changed from sandy and strongly acid to clay-loam and slightly acid at Gawel 1, and from sandy and strongly acid to clay-loam and alkaline at Gawel 2. Soil water content and soil nutrient had increased within the ReviTec site compared to the outside with the application of compost-biochar-mycorrhiza treatment as the most promising over the two years of monitoring. Such results suggest that ReviTec approach can be used in sustainable restoration of soil hardé.

“…Human activity is altering the time scale of soil formation. It has been argued that the anthropogenic factor is orders of magnitude faster than the “natural” processes that affect soil formation (hundreds of years vs hundreds of thousands and even millions of years, respectively 24 ). It is noted that there are also several fast, natural processes, like landslides or flood events; although many of them are attributed to climate change, they also involve anthropogenic factors.…”

Soilthe thin outer skin of the Earth's landis a critical and fragile natural resource. Soil is the basis for almost all global agriculture and the medium in which most terrestrial biological activity occurs. Here, we reconsider the five forming factors of soil originally suggested more than a century ago (parent material, time, climate, topography, and organisms) and updated over the years to add human activity as the sixth forming factor. We demonstrate how present anthropogenic activity has become the leading component influencing each one of the original forming factors. We thus propose that, starting from the Anthropocene, human activity should no longer be considered as a separate forming factor but rather a main driving force of each of the five original ones. We suggest that the importance of soil and the strong direct and indirect effects of anthropogenic factors on soil-forming factors should be considered together to ensure sustainability of this critical resource.

“…Environmental hazards lead to over a hundred human illnesses and traumas that cause around 12.6 million deaths every year worldwide (Prüss-Ustün et al, 2016). Environmental contamination by various substances such as metals, metalloids and organic compounds like hydrocarbons is a global ecological problem (Dror et al, 2016;Prüss-Ustün et al, 2016). Polycyclic aromatic hydrocarbons (PAH) are chemically stable, hydrophobic contaminants causing dramatic damages to living organisms (IARC, 2018).…”

Biostimulation and bioaugmentation have been proposed as sustainable alternatives to physicochemical treatments for the environmental decontamination of polycyclic aromatic hydrocarbons (PAH). PAH-removing Pseudomonas monteilii P26 and Gordonia sp. H19, alone or combined with organic and inorganic biostimulants, were previously proposed as candidates to be included in biotechnological products to be used in eco-friendly decontamination processes. This work aims to study the effect of biostimulants on the growth, cell hydrophobicity and emulsifying activity of P. monteilii P26 and Gordonia sp. H19, and to evaluate the influence of selected biostimulants and bacterial inoculation procedure on PAH bioremoval. A complete factorial experimental design was applied to determine the effect of KNO 3 , K 2 HPO 4 , corn steep liquor (CSL) and a PAH mixture on the growth, cell hydrophobicity and bioemulsifying activity of bacterial cultures. The kinetics of PAH bioremoval was evaluated in simultaneous and sequential cultures of P. monteilii P26 and Gordonia sp. H19 in the presence of selected biostimulants. CSL was the only nutrient that exerted positive effects on all responses evaluated, although these effects were not significant in all cases. In mixed cultures, maximum bioremoval of phenanthrene and pyrene was evidenced when the bacterial strains were simultaneously inoculated, independently of the presence or absence of CSL. These results support the biotechnological characterization of two PAH-removing autochthonous Patagonian strains.

Microchemical contaminants as forming agents of anthropogenic soils

Abstract: Within historically accepted, major soil-forming major processes, the role of chemicals as a human-induced factor was neglected until the middle of the last century.
