Characterization, bioenergy value, and thermal stability of biochars derived from diverse agriculture and forestry lignocellulosic wastes

Preparation and nutrient release kinetics of enriched biochar-based NPK fertilizers and agronomic effectiveness in direct seeded rice

“…Proximate and elemental analysis representing the recalcitrance and stability of biochar relates the qualitative traits of resultant biochar (Table 1). These results are common for biochar from different feedstock's produced at low temperature (Chaturvedi et al, 2021;Shaheen et al, 2019).…”

“…Proximate and elemental analysis representing the recalcitrance and stability of biochar relates the qualitative traits of resultant biochar (Table 1). These results are common for biochar from different feedstock's produced at low temperature (Chaturvedi et al, 2021;Shaheen et al, 2019 (Wen et al, 2017). Under pyrolysis temperature of 200 to 400 ℃, the feedstock was carbonized incompletely, so numerous oxygen functional groups were remaining in biochar, which could provide abundant negative potential charges for the adsorption of NH 4 + , owing to hydrogen bonding and electrostatic interactions (Cai et al, 2016).…”

“…Due to the farming and ecological applications, enriched biochar fertilizers have received growing attention. Recent studies suggest that biochar-based fertilizers delay the release of nutrients in the soil displaying a slow-release effect (Chaturvedi et al 2021). Enrichment of soil with biochar-based fertilizer adjust the soil pH, reduce the bulk density, improve soil aeration and water permeability and retention to increase the crops yield (Gao et al 2012;O'Connor et al 2018).…”

“…Control-release fertilizers delays the availability of nutrients after application for plant uptake and use, or which extends the nutrient availability to the plant for signi cantly longer period compared to the conventional fertilizers and thereby enhance nutrient use e ciency. Biochar prepared from agricultural wastes viz., rice straw and husk may be utilized as a suitable matrix to prepare control release fertilizers (Singh et al 2020;Chaturvedi et al 2021). It will not only enhance NUE but also improve soil health and crop yield with most economic management of agro-wastes.…”

Biochar‐assisted eco‐restoration of coal mine degraded land to meet United Nation Sustainable Development Goals

“…-p interactions between ring structure of tetracycline molecule and graphite-like sheets of biocharsLin et al (2012) agricultural wastes, forest sweeps and animal manure will produce about 50% biochar, which is returned to the soil, and 50% bioenergy in the form of syn-gas and bio-oil. In a study conducted byChaturvedi et al (2021), they reported that the heating values of raw biomasses vary in the range of 13-18 MJ kg À1 with the highest observed for Eucalyptus (18.0 MJ kg À1 ) followed by L. camera (16.63 MJ kg À1 ) and minimum for rice straw (13.00 MJ kg À1 ), which can be used for as biofuel after pyrolysis.
