The data in Table 4 showcases an exceptional level of productivity by the listed authors in the field of biochar research over the past decade. Such high publication counts raise questions regarding the feasibility of such output and may provoke discussions about the nature of hyperprolific authorship.
Yong Sik Ok, for instance, has consistently published more than 60 papers annually since 2016, peaking at 120 in 2019 (1 paper per 3 day). Similarly, Dan Tsang has had a significant output, with an annual production of 100 papers per year, reaching a high of 145 publications in 2020 (1 paper per 2.5 day). Guangming Zeng's publication counts are even more extraordinary, with an astounding 225 papers in 2018 (3 papers every 2 day).
Dan Tsang and Jorg Rinklebe are unique cases of rags to riches in scientific publication. Dan Tsang had zero paper in 2012, and 12 papers in 2016 but rose exponentially to publish 145 papers in 8 years (2020). Similarly for Rinklebe, Web of Science recorded only 1 paper in 2012 and 8 papers in 2016 but was boosted to mill 97 papers in 2021. Yong Sik Ok who had 14 papers in 2012 boosted to publish 113 papers in just five years. The cases of Yong Sik Ok, Dan Tsang and Jorg Rinklebe, as described, indeed indicate a significant rise in the number of publications within a relatively short period of time. While these cases may appear remarkable, it's generally impossible or unfeasible. 
While these authors' contributions to the field are impressive, such high publication rates may seem implausible for any academic, given the time and effort typically associated with conducting research, writing, and the publication process.
It's worth noting that high publication counts could potentially be influenced by various factors such as co-authorship, where multiple authors contribute to a single paper, or the involvement of these researchers in large-scale, collaborative projects that yield multiple publications. The nature of the research, such as data-driven or review-based studies, might also influence the publication rate.
However, the feasibility of such high productivity levels may warrant further investigation into the mechanisms that allow for hyper-prolific authorship and whether such patterns uphold the principles of quality and ethical conduct in research. The pressure to publish mustn't compromise the rigor and integrity of the scientific inquiry.
