“…Further, it has other potential benefits such as improving soil fertility, encouraging seed germination, enhancing vegetative growth of plants, increasing disease resistance of soil, adsorbing toxic pollutants, improving water retention capacity of the land, etc. [6,7]. Besides, biochar can be used as energy fuel and carbon sink.…”

Interest in biochar production from organic waste has been growing in recent years due to its broad applicability, availability, and smoother production. Biochar production techniques are being continuously modernized to improve the production rate and quality. Though numerous methods have been reported in the recent past, a systematic classification of the same is yet to be explored. Based on the advancement of the techniques being employed for biochar production and modification of conventional methods, we have categorized all major techniques of biochar production into two primary classes. In the traditional approach, ancient methods and conventional pyrolysis techniques (Slow and Fast pyrolysis) are included, whereas, in modern approaches, several advanced technologies such as Gasification, Torrefaction, Hydrothermal carbonization, Electro-modification, along with modified traditional methods (Flash pyrolysis, Vacuum pyrolysis, and Microwave pyrolysis) are comprised. Further, the systematic review was intended to evaluate various types of feedstocks (agricultural biomass, forest/woody biomass, aquatic biomass, urban waste, and paper waste) with their potential to produce biochar. It was observed that the feedstock containing high cellulose was found to be helpful in improving the overall properties of biochar, including enhanced adsorptive action and retention of nutrients.

“…Meta‐analysis shows that biochar significantly translates to increased crop biomass and plant macronutrients across all soil types and climates (Biederman & Harpole ), but the largest positive influences on plant production have been shown in acidic, nutrient poor soils (Jeffery et al ). In mine substrates, biochar has shown positive effects on native plant growth (Anawar et al ; Roberts et al ), but inconsistent effects on plant biomass (Jones et al ; Adams et al ) Thus, the utility of biochar in restoring plant communities is not clear.…”

Extreme growing conditions inhibit restoration in sandpit mines. Co-amendment of soil conditioners such as biochar, compost, and arbuscular mycorrhizal fungi (AMF) may alleviate these stresses and lead to a more successful restoration. We conducted a multiyear restoration experiment in a sandpit in Southern Ontario, Canada, following industrial-scale grassland restoration protocols. The sandpit substrate was sand with low carbon (C) and nutrients. We tested the effect of biochar, compost, and AMF inoculum in two experiments (plant plugs vs. seed application). In the plant plug trial, we investigated the treatment effects on the growth of eight grassland plant species and colonization of plant roots by AMF over two growing seasons. We found that co-amending soils with compost plus biochar (20 T/ha + 10 T/ha) was more beneficial than other amendment combinations. Amendments including AMF were not more beneficial to plant growth than those without AMF. In the seed application trial, direct inoculation of AMF in the field combined with high compost addition (20 T/ha or 40 T/ha) resulted in the highest plant cover compared to other treatment combinations. Our results indicate that co-amending sandpit substrates with biochar, compost, and AMF are practical restoration tools that enhance grassland restoration.

“…In comparison to the biochar prepared from high lignocellulosic biomass, the C content is lower in biochar prepared from seaweeds. However, seaweed biochar has a high concentration of exchangeable nutrients particularly N, P, K, Ca, and Mg and cation exchange capacity (CEC) which makes them very effective in nutrient retention and biosorbent of heavy metals for environmental remediation [3,41,42].…”
