“…One of the main aims of introducing bioremediation treatments to degraded areas is to prevent the migration of contaminants into the food chain where they could pose a threat to human health. 21 There are many technologies for the bioremediation of contaminated areas.…”

Transdisciplinary approaches that provide holistic views are essential to properly understand soil processes and the importance of soil to society and will be crucial in the future to integrate distinct disciplines into soil studies. A myriad of challenges faces soil science at the beginning of the 2020s. The main aim of this overview is to assess past achievements and current challenges regarding soil threats such as erosion and soil contamination related to different United Nations sustainable development goals (SDGs) including (1) sustainable food production, (2) ensure healthy lives and reduce environmental risks (SDG3), (3) ensure water availability (SDG6), and (4) enhanced soil carbon sequestration because of climate change (SDG13). Twenty experts from different disciplines related to soil sciences offer perspectives on important research directions. Special attention must be paid to some concerns such as (1) effective soil conservation strategies; (2) new computational technologies, models, and in situ measurements that will bring new insights to in-soil process at spatiotemporal scales, their relationships, dynamics, and thresholds; (3) impacts of human activities, wildfires, and climate change on soil microorganisms and thereby on biogeochemical cycles and water relationships; (4) microplastics as a new potential pollutant; (5) the development of green technologies for soil rehabilitation; and (6) the reduction of greenhouse gas emissions by simultaneous soil carbon sequestration and reduction in nitrous oxide emission. Manuscripts on topics such as these are particularly welcomed in Air, Soil and Water Research.

“…expected to spread in the soil as quickly as the microbial inoculum, which may explain why phytoremediation alone would need a longer treatment time than bioaugmentation, especially when the plant growth is affected by pollutants (Zhang et al, 2020).…”

“…Inoculant increased the contaminant removal more than the black locust, yet the inoculant and black locust combination was the most efficient remediation treatment possibly due to the root exudates in rhizosphere, which are known to stimulate contaminant-degrading microorganisms and to enhance biodegradation ability ( Grayston et al, 1997 ; Walker et al, 2003 ; Kechavarzi et al, 2007 ; Neumann, 2007 ). The plant root system is not expected to spread in the soil as quickly as the microbial inoculum, which may explain why phytoremediation alone would need a longer treatment time than bioaugmentation, especially when the plant growth is affected by pollutants ( Zhang et al, 2020 ).…”

“…The mode of action of the biochar was via an increase in the fraction of Cd bound to soil OM and the presence of its oxides and carbonates, thereby reducing Cd availability and potential plant uptake. More recent work shows that biochar production temperature can be used as factor in the development of biochars to promote phytoremediation (Zhang et al 2020a). However, despite an understanding of the mechanisms of biochar action on soil HM and the many positive experimental effects of biochar application on plant growth in non-contaminated soils (Lehmann et al 2011, Prendergast-Miller et al 2014, we have very little insight into the longer-term effects of biochar on HM remediation of plant performance or soil HM availability.…”

The focus of this study is on the soil physicochemical, biological, and microbiological processes altered by biochar application to heavy metal (HM) contaminated soils. The aim is to highlight agronomical and environmental issues by which the restorative capacity of biochar might be developed. Literature shows biochar can induce soil remediation, however, it is unclear how soil processes are linked mechanistically to biochar production and if these processes can be manipulated to enhance soil remediation. The literature often fails to contribute to an improved understanding of the mechanisms by which biochar alters soil function. It is clear that factors such as biochar feedstock, pyrolysis conditions, application rate, and soil type are determinants in biochar soil functionality. These factors are developed to enhance our insight into production routes and the benefits of biochar in HM soil remediation. Despite a large number of studies of biochar in soils, there is little understanding of long-term effects, this is particularly true with respect to the use and need for reapplication in soil remediation.
