“…Biochar is absorbed into the soil once it is applied, making it impossible to remove. Because of its fine-grained texture, biochar cannot be used to generate energy in combined heat and power plants because it would be difficult to evenly feed thermal energy systems with the required amount of biochar [60]. There is always a possibility that dangerous materials found in biochar, like heavy metals, could be released.…”

Improving the condition of the soil is essential for successful agriculture since it increases crop output and soil fertility. Applying biochar to the soil can boost crop yields and soil fertility. Biochar is a solid carbon-rich substance made by pyrolyzing biomass, which includes trash, wood, and agricultural crop leftovers under low oxygen conditions. Because biochar has potential uses in waste recycling, soil nutrient retention, and greenhouse gas emission reduction, it is significant for sequestering carbon. Over the last two decades, biochar has received substantial attention in agriculture and the environment. Agriculture soil productivity has long been increased by the application of synthetic fertilizers, some of which leached into the environment and released greenhouse gases (GHG). Improving soil microbiology and water retention, as well as increasing fertilizer efficiency, are some of the basic problems facing agricultural practices. Biochar is becoming more and more popular as a soil supplement to increase crop yields and sequester carbon. Biochar is one of the many conservation agricultural techniques that can be used to improve soil fertility, and crop productivity, and slow down global warming. It is also a readily available and important input for sustainable agriculture. Furthering global food security, biochar may improve soils' ability to produce crops under various biotic and abiotic stress. This review examines the numerous uses of biochar to guarantee the long-term, safe enhancement of soil fertility. An overview of the characteristics, manufacturing process, and applications of biochar in agriculture is given in this review. Researchers, farmers, and academics interested in using biochar might find this review to be a helpful resource.

“…Biochar, primarily derived from the pyrolysis process involving the combustion of biomass or organic material under limited oxygen conditions and low temperatures (≤700°C), plays a crucial role in enhancing soil water retention and reduce nitrous oxide emission (Mukhtar et al, 2023;Rassaei, 2023Rassaei, , 2024. Physically, biochar is highly porous, thus its application to soil is considered to improve a range of soil physical and chemical properties including soil moisture content, plant available water content (PAWC) (Hardie et al, 2014), water retention capacity and nutritional status of rhizosphere (nitrogen, phosphorous, and potassium) (Ghassemi-Golezani et al, 2023). Moreover, this is achieved by reducing soil bulk density (Abel et al, 2013;Da Silva Mendes et al, 2021), increasing soil pore volume (Obia et al, 2016;An et al, 2022), and promoting soil aggregation (Herath et al, 2013;Islam et al, 2021).…”

IntroductionAddressing the global demand for rice production necessitates innovative approaches to enhance upland rice yield in rainfed agroecosystems, considering the challenges posed by increasing population, limited land fertility, low productivity, and water availability.MethodsIn this study, our study investigated the impact of biochar and organic fertilizer on ten promising rice lines (G1 – G10) and two control (G11 – G12) cultivars under rainfed conditions. The experimental design used a split-plot design with four soil amendments as main plots, namely control, organic fertilizer, biochar, and biochar + organic fertilizer and 12 rice genotypes as subplot.ResultsThe absolute attainable yield gaps, differentiating organic and control (GAP1), biochar + organic and control (GAP2), and biochar and control (GAP3), ranged from 1.5 to 3.7 or increased of 91–580%, 0.8 to 3.5 (72–560%), and 0.6 to 2.58 tons/ha (58–472%), respectively. Notably, G2 + organic exhibited the highest positive absolute yield gap, ranging from 1.1 to 5.38 tons/ha, based on the yield gap matrix. Furthermore, genotype main effect plus genotype-environment interaction (GGE) biplot analysis identified G2 as the most promising rice line, displaying superior yield performance for cultivation in biochar and organic amended soils.DiscussionThese findings provide valuable insights for farmers, governments, and stakeholders, offering a roadmap to optimize rainfed areas for rice production, serving as practical guidance to enhance overall rice productivity in rainfed agroecosystems.
