“…Biochar is a solid, carbon-rich substance created through the pyrolysis of various feedstocks with a limited amount of oxygen and has a well-developed porous structure and flexible functionality (Majumder et al, 2023). Several studies showed as biochar supports the shift to Sustainable Development Model easier by promoting climate change mitigation (Lehmann et al, 2021), increasing the amount of carbon in the soil (Novotný et al, 2023;Akbar et al, 2023a), lowering soil pollution (Rahim et al, 2022;Saleem et al, 2023), regulating nutrient and water cycles (Akbar et al, 2023b;Pan et al, 2021), and changing the physicochemical characteristics of soil (Mansoor et al, 2021), improving microbial activity (Palansooriya et al, 2019), enhancing plant performance and agricultural output (Yu et al, 2019). The previously listed benefits are mainly due to biochar's surface properties and the functional groups that facilitate their apparent performance, but it is impossible to ignore the biochar's in situ temporal performance in the complex soil system.…”

The copious amounts of data generated through publications play a pivotal role in advancing Science, Technology, and Policy. Additionally, they provide valuable and detailed information on research topics, emerging thematic trends, and critical issues that demand increased focus and attention. Over the last few decades, biochar has produced an extensive body of high-quality papers and played a crucial part in achieving the long-term Sustainable Development Goals of the 2030 agenda of the United Nations about “Climate Change,” “Sustainable Agriculture,” “Environmental Sustainability,” “Zero Hunger,” “Human Wellbeing,” and “Circular Bioeconomy”. However, most of the research is on biochar that has been modified or functionalized using various chemical reagents or catalysts and reported widely in peer-reviewed, high-quality journals. No prior work analyzed the bibliometric data on aging biochar with (a)biotic processes. This study presents an innovative data-driven bibliometric analysis technique and paradigm for extracting the essence of the available peer-reviewed literature data to offer new perspectives on the research opportunities and potential of aged biochar for agro-environmental applications. The bibliometric data analysis indicates that aging biochar research for agro-environmental applications received attention, advanced, and resulted in 165 high-quality publications in reputed journals between 2011 and 2023. However, it is evident that there is still a considerable need for further attention in this area. The identification of the research trends/frontiers shows that biochar production effectively employs various biomass resources, aging with different (a)biotic factors, characterization, effects on global climate change, long-term carbon sequestration in soil, soil nutrient dynamics, restoration of multi-polluted soils and sediments, and plant growth all require continuous attention both now and in the future.

“…To compensate for the lack of soil fertility (low N, P, and K), farmers across the globe often overapply chemical fertilisers in the expectation of increasing crop yields [4]. Urea is the most commonly used low-cost nitrogen fertiliser, and when it is applied to soil, it is rapidly converted to ammonium and carbon dioxide by microbially generated urease enzymes, thus providing essential nutrients for plant growth and development [5]. However, overapplication of urea may lead to several problems, such as soil acidification and poor fertiliser utilisation.…”

Objective: In this study, we aimed to investigate the effects of facile combinations of biochar and N, P, and K fertilisers on the growth and physiological characteristics of Lithocarpus litseifolius seedlings, and to optimise the biochar/NPK ratio of Lithocarpus litseifolius. Method: A four-factor three-level orthogonal method was used to conduct a field experiment using 2-year-old Lithocarpus litseifolius. Nine fertiliser treatments and one control treatment (CK, i.e., no fertiliser) were established in a completely randomised block group with six replications of ten treatments. The plants were planted in October 2020 and harvested in November 2021, and fertiliser was applied once in April 2021 and once in July 2021. Results: Rational application could effectively promote the growth of Lithocarpus litseifolius, and T4(C2N1P2K3) produced the highest increase in plant height growth (17.03 cm), diameter growth (5.47 mm), soluble sugar (94.60 mg/g), soluble protein (4.59 mg/g), and phlorizin (old leaf: 16.00%; tender leaf: 15.13%); T8(C3N2P1K3) resulted in the highest chlorophyll a content (1.46 mg/g), chlorophyll b content (0.62 mg/g), and total chlorophyll content (2.08 mg/g), and T1(C1N1P1K1) resulted in the highest contents of starch (11.60 mg/g) and trilobatin (old leaf: 0.29%; tender leaf: 2.28%). The indicators corresponding to the above three treatments were significantly higher than those under the other treatments (p < 0.05). The results as analysed by the affiliation function method show that the highest mean value of the affiliation function was 0.645 after T4(C2N1P2K3) treatment. Conclusions: The combination of biochar and nitrogen, phosphorus, and potassium fertilisers can effectively increase the biomass and active components of Lithocarpus litseifolius while reducing the amount of chemical fertiliser applied. A comprehensive analysis of the results showed that the T4 treatment (biochar: 20 g/plant; urea: 10 g/plant; superphosphate: 9 g/plant; potassium chloride: 12 g/plant) resulted in the highest comprehensive score, with the highest increase in plant height growth, ground diameter growth, root–crown ratio, soluble sugar, soluble protein, and phlorizin, as well as other indicators.

Many years ago, widespread and ineffective technologies led to significant ecological contamination, primarily due to heavy metals (HMs), particularly lead (Pb) and cadmium (Cd). Plant growth in heavy metals contaminated and calcareous soil is a challenge for all the growers worldwide. Several organic and inorganic amendments are used by researchers in different types of soils. However, their impact on soil contaminated with toxic metals and alkaline in reaction is still unclear. Therefore, the current pot experiment investigates the relative effect of organic (wheat straw biochar and farmyard manure) at 10 and 20 t ha−1 and inorganic (diammonium phosphate and gypsum) at 100 and 150 kg ha−1 amendments on NPK availability, soil organic matter, soil properties, and maize growth under Cd and Pb stress. Highest soil pH (7.61), soil electrical conductivity (0.25 dS m−1), soil organic matter (1.40%), plant height (92 cm), shoot dry weight (41 g), and root dry weight (5.5 g) were observed because of biochar application at 20 t ha−1. While the highest total nitrogen (N) (0.13%), and phosphorus (P) (8.16 mg kg−1) were recorded with diammonium phosphate application at 150 kg ha−1, moreover, application of farmyard manure at 20 t ha−1 increased the soil potassium (K) (108.14 mg kg−1). Biochar application at 20 t ha−1 greatly reduced the toxic metals bioavailability with a high immobilization index, that is, Cd (52%) and Pb (43.79%) lead to lower concentrations of metals in roots and shoots as well. A negative correlation was identified between soil pH, soil organic matter, and soil Cd, Pb, demonstrating the positive impact of biochar in terms of the reduction of toxic metals by enhancing pH and soil organic matter, found to be the most effective amendment for soil improvement and plant growth under Cd and Pb stress condition.
