“…Moreover, the desorption of nitrification or denitrification inhibitors adsorbed by biochar due to its blocked pores and decreased adsorption capacity may decrease the suppression of the N 2 O production (Spokas 2013). These findings could explain the gradual weakening or even disappearance of the N 2 O abatement effect of biochar found in the metaanalysis as the duration of the experiment increased (Guo et al 2023). However, opposite results have also been observed, possibly because the labile C of aged biochar (6 years) decreased significantly, with the remaining recalcitrant C unavailable to most denitrifiers (He et al 2019).…”

Biochar has gained significant attention in agricultural and environmental research over the last two decades. This comprehensive review evaluates the effects of biochar on soil organic carbon (SOC), emission of non-CO2 greenhouse gases, and crop yield, including related mechanisms and major influencing factors. The impacts of biochar on SOC, methane and nitrous oxide emissions, and crop yield are controlled by biochar and soil properties and management practices. High-temperature biochar produced from lignin-rich feedstocks may decrease methane and nitrous oxide emissions in acidic soils and strengthen long-term carbon sequestration due to its stable aromatic structure. In contrast, low-temperature biochar from manure may increase crop yield in low-fertility soils. Applying biochar to farmlands in China can increase SOC content by 1.9 Pg C and reduce methane and nitrous oxide emissions by 25 and 20 Mt CO2-eq year−1, respectively, while increasing crop yields by 19%. Despite the increasing evidence of the positive effects of biochar, future research needs to explore the potential factors that could weaken or hinder its capacity to address climate change and secure crop production. We conclude that biochar is not a universal solution for global cropland; however, targeted applications in fields, landscapes, or regional scales, especially in low fertility and sandy soils, could realize the benefits of biochar as a climate-smart measure.Highlights The findings of research on biochar's effects on soil C sequestration, GHG mitigation, and crop production were summarized. The factors influencing the impact of biochar on soil functioning were reviewed. The effects of biochar on soil C sequestration and GHG mitigation in farmlands of China were quantified.

“…However, these models still have limitations (see original manuscripts for more details). For example, they include short‐term laboratory experiments that might differ from real soil effects (e.g., biochar‐induced changes in soil N 2 O emissions are suspected to be only short‐term or may not be observable on field scale experiments (Borchard et al., 2019; Guo et al., 2023; Verhoeven et al., 2017)). Biochar's effect on soil NO x emissions is less studied than N 2 O, and the long‐term effects are unclear.…”

Negative emissions are essential to limit global warming, but their large‐scale deployment rises sustainability concerns. At the same time, agricultural soils are under increasing threat of degradation, as measured by losses in soil organic matter, water holding capacity, and nutrient retention, with increasing negative effects on plant productivity. Biochar from biomass residues is a technically mature option that does not compete for land and can typically restore key functions of degraded soils while delivering negative emissions. However, quantitative estimates of its potentials in Europe and a detailed spatially‐explicit analysis of the co‐benefits and trade‐offs for agricultural land are unclear. Here, we estimate an annual negative emission potential of biochar from forest and crop residues available in Europe from 1.7% to 3.9% of 2021s European greenhouse gas emissions (15.2%–35% of the agricultural emissions), depending on residue potentials and biochar scenarios. At the same time, biochar application to cropland increases water holding capacity (+6.5%‐9%), crop production (+7.1%‐8.4%), NH3 volatilization (+21.7%‐24.2%), and reduces soil N2O emissions (−13.7%–34.7%) and nitrogen leaching (−17.5%–22.7%). There are spatially heterogeneous trade‐offs for some soil effects (ammonia volatilization and yields) and air pollution (mainly due to emissions from biochar systems). Biochar offers synergistic solutions that co‐deliver across different sustainability challenges, but its optimal deployment requires strategies tailored to local conditions.

“…Konstruksi permukaan biochar bersifat permeabel dengan kandungan karbon tinggi yang memiliki struktur berbeda, Sifat biochar seperti porositas dan kapasitas adsorpsi yang tinggi, juga telah disarankan untuk digunakan dalam pengembangan pembawa N untuk pertanian berkelanjutan (Ippolito et al, 2020) (Chen et al, 2018;Guo et al, 2022;Laghari et al, 2016). Ketika ditempatkan di dalam tanah, C yang bandel dapat bertahan ratusan hingga ribuan tahun, dan oleh karena itu, penerapan biochar pada lahan mungkin berperan dalam mitigasi iklim (Borchard et al, 2019b;Li et al, 2019;Sohi et al, 2010;Wang et al, 2020).…”

Biochar is widely used for water and soil remediation due to its local availability and low production costs. However, its effectiveness depends on the physicochemical properties related to the raw material and pyrolysis temperature, as well as the environmental conditions where it is used. Additionally, biochar is susceptible to natural aging caused by changes in soil or sediment moisture, which can alter its redox properties and interactions with contaminants such as arsenic. Therefore, we are interested in conducting fundamental research on raw materials from grass types and their influence on the growth and production of QPM corn plants. In this research, we carried out laboratory content tests and field experiments. The treatments were: p0 control, p1 = 3 tons ha-1 biochar, p2 = 6 tons ha-1 biochar, p3 = 9 tons ha-1, p4 = 12 tons ha-1, p5 = 15 tons ha-1. The experimental results showed that the administration of biochar made from Arundo Spp. 12 tons Ha-1 can increase the effective growth and production of corn plants
