“…The use of char in agriculture and its positive effects have been extensively reviewed [ 16 , 34 , 35 , 36 , 37 ]. Moreover, its porous structure represents a perfect habitat for microbial growth [ 17 , 38 , 39 ]. The high cargo capacity of char was utilized and demonstrated in this work.…”

Commodity crops, such as wheat and maize, are extremely dependent on chemical fertilizers, a practice contributing greatly to the increase in the contaminants in soil and water. Promising solutions are biofertilizers, i.e., microbial biostimulants that when supplemented with soil stimulate plant growth and production. Moreover, the biofertilizers can be fortified when (i) provided as multifunctional consortia and (ii) combined with biochar with a high cargo capacity. The aim of this work was to determine the molecular effects on the soil microbiome of different biofertilizers and delivery systems, highlight their physiological effects and merge the data with statistical analyses. The measurements of the physiological parameters (i.e., shoot and root biomass), transcriptomic response of genes involved in essential pathways, and characterization of the rhizosphere population were analyzed. The results demonstrated that wheat and maize supplemented with different combinations of selected microbial consortia and biochar have a positive effect on plant growth in terms of shoot and root biomass; the treatments also had a beneficial influence on the biodiversity of the indigenous rhizo-microbial community, reinforcing the connection between microbes and plants without further spreading contaminants. There was also evidence at the transcriptional level of crosstalk between microbiota and plants.

“…There have been several physical and chemical methods also are available for the remediation of soils contaminated with HMs, including encapsulation, soil washing, freezing, electrokinetic remediation, membrane filtration, reverse osmosis (RO), 3 electrodialytic remediation (EDR), landfilling, nanomaterials, immobilization, and surface capping (Barati et al, 2018;Liu et al, 2018;Kiran and Prasad, 2019;Shah and Daverey, 2020). However, all the aforementioned techniques have several limitations, including high economic costs, creating secondary pollution for the environment, inapplicability in wide areas, high energy consumption, and extensive chemical needs (Paz-Alberto and Sigua, 2013;Gkorezis et al, 2016;Lin et al, 2019;Yrjälä and Lopez-Echartea, 2021), therefore, finding cheaper and more effective methods can be a remedial to reduce pollution in soils contaminated with HMs.…”

Phytoremediation is one of the cheapest and most widely used technologies for stabilizing and extracting pollutants from contaminated sites. Recently, a variety of solutions, such as the use of different elements, compost, nanoparticles, microorganisms, etc., have been explored for improving and accelerating the phytoremediation process. Biochar has also gained attention for its affordability, abundance, ability to improve soil structure and plant morpho-physiology and biochemistry, lack of environmental hazards, etc. As a first step, this study aimed to provide an overview of biochar’s properties, and operation by identifying the method of production and examining the differences between different types of biochar. Following that, by examining various factors that pollute the environment, the influence of different types of biochar on phytoremediation efficiency was explored. Also, in this study, an attempt has been made to examine the effect of the combination of biochar with other factors in improving the phytoremediation of pollutants, as well as the use of the residues of phytoremediation for the production of biochar, so that future research can be planned based on the results obtained.

“…Numerous remediation strategies depending on their mobilization or immobilization mechanisms have indeed been established to address these issues ( Akcil et al, 2015 ; Wang et al, 2021 ). However, they are typically very expensive, and planned remediation is often delayed due to the absence of sufficient funds ( Yrjälä and Lopez-Echartea, 2021 ). Unique nature-based substances are emerging that ought to be cost-effective in remedial work but necessitate further development because they require useful insights into the structure–function relationships ( Byrne et al, 2018 ).…”

A number of anthropogenic and weathering activities accumulate heavy metals in soils, causing adverse effects on soil characteristics, microbial activity (diversity), agricultural practices, and underground aquifers. Controlling soil heavy metal pollution is difficult due to its persistence in soils, resulting in the deposition and transmission into the food web via agricultural food products, ultimately affecting human health. This review critically explores the potential for remediation of metal-contaminated soils using a biochar-based responsible approach. Plant-based biochar is an auspicious bio-based residue substance that can be used for metal-polluted soil remediation and soil improvement as a sustainable approach. Plants with rapid growth and increased biomass can meet the requirements for phytoremediation in large quantities. Recent research indicates significant progress in understanding the mechanisms of metal accumulation and contaminant movement in plants used for phytoremediation of metal-contaminated soil. Excessive contamination reduces plant biomass and growth, which has substantial hyperaccumulating possibilities and is detrimental to the phytoremediation process. Biochar derived from various plant sources can promote the growth and phytoremediation competence of native or wild plants grown in metal-polluted soil. Carbon-enriched biochar encourages native microbial growth by neutralizing pH and providing nutritional support. Thus, this review critically discusses the influence of plant and agricultural waste-based biochar on plant phytoremediation potential in metal-contaminated soils.
