It is with great pleasure that I write this testimonial for my PhD advisee, Md. Nayem Hasan Munna. He has consistently demonstrated high academic performance, dedication, and commitment to excellence. He is committed to scientific rigor, intellectual curiosity, and perseverance in the field of soil science and climate-resilient agriculture. Munna’s doctoral research on soil physical quality and sustainable land management has addressed some challenges in ecological restoration and climate-resilient farming. He conducted field experiments and laboratory analyses and demonstrated a strong capacity to integrate practical fieldwork with robust scientific inquiry. Beyond his dissertation research, Munna has been actively involved in scholarly collaboration, co-authoring book chapters, review articles, and original research papers. Indeed, his research will continue to generate knowledge of relevance to ecological restoration and climate-resilient agriculture.

I had the privilege of teaching Munna in my graduate-level Soil Fertility course, ENR5270, where he stood out as one of the best students in the class. He earned an outstanding grade of 98.28% (A), which reflects not only his strong grasp of the subject matter but also his consistent effort, focus, and commitment to the subject of soil and environmental science. He was always engaged, asked thoughtful questions, and performed at a very high level on both assignments and exams. Outside the classroom, I have interacted (and continue to do so) with Munna through seminars and discussions within the CFAES Rattan Lal Center for Carbon Management and Sequestration. In these settings, he has showed genuine curiosity, professionalism, and the ability to connect soil fertility with larger issues of sustainable agriculture and environmental management. Munna is diligent, respectful, and motivated. He works well with others, communicates clearly, and shows maturity beyond his career stage.

Md Nayem Hasan Munna has completed his Master’s thesis entitled “Production and Characterization of Slow Pyrolysis Acid-Modified Biochars and Their Effects on Soil Salinity” under my supervision. His research work demonstrated strong scientific rigor and deep commitment to sustainable agriculture and environmental management, particularly in developing biochar-based solutions to improve soil health and reduce salinity stress. Mr. Munna has consistently shown exceptional academic ability, curiosity, and discipline throughout his graduate studies. His analytical thinking and hands-on laboratory skills were evident in the design, execution, and interpretation of his thesis experiments. He combines theoretical knowledge with practical problem-solving, reflecting a maturity well beyond his academic level. I am confident that Md Nayem Hasan Munna will continue to make significant contributions to the field of soil and environmental science.

It is a pleasure to write this testimonial for Md Nayem Hasan Munna, whose academic excellence, research capability, and professional integrity have been consistently impressive. Mr. Munna has built strong expertise in soil science, with research spanning biochar applications for saline soil remediation and soil physical quality improvement under long-term no-till management. His work demonstrates exceptional experimental precision, analytical ability, and scientific rigor. He combines field research with advanced laboratory analyses to address critical challenges related to soil health, nutrient management, and sustainable agriculture. He also exhibits excellent communication skills, professionalism, and a collaborative spirit. Given his technical skills, academic accomplishments, and passion for research, I am confident that Md Nayem Hasan Munna will continue to contribute meaningfully to the advancement of soil and environmental sciences.

It is a great pleasure to provide this testimonial for Md Nayem Hasan Munna, whose academic and research journey I have had the privilege to follow from his Master’s program in Bangladesh to his ongoing Ph.D. studies at The Ohio State University. During his Master’s degree at the University of Barishal, he conducted his thesis under my supervision in the Agronomy Laboratory at Patuakhali Science and Technology University, titled “Production and Characterization of Slow Pyrolysis Acid-Modified Biochars and Their Effects on Soil Salinity.” His research was well designed and executed, addressing soil salinity challenges in coastal Bangladesh with scientific rigor and practical relevance. Mr. Munna is a highly motivated and disciplined researcher with strong analytical ability, a deep understanding of soil processes, and a genuine passion for sustainable agriculture. His collaborations on a book chapter and an original research article further reflect his commitment to scientific excellence and scholarly contribution.

I came to know Md Nayem Hasan Munna during my time as a visiting research scholar at the CFAES Rattan Lal Center for Carbon Management and Sequestration (Lal Carbon Center). During this period, we attended seminars together, visited long-term experimental sites at Waterman Farm, and engaged in many stimulating academic conversations. This ability to bridge concepts across disciplines demonstrates his intellectual curiosity, creativity, and analytical depth. Mr. Munna has developed a strong expertise in soil processes, ecological restoration, and sustainable land management. His doctoral research on soil physical quality and sustainable land management is both rigorous and highly relevant, building upon long-term no-till experiments at OSU. He skillfully combines demanding field work with precise laboratory analysis, while also contributing to collaborative publications and scholarly writing. His originality, clarity of thought, and dedication to translating science into practice mark him as an emerging leader in the field.

I am familiar with Md Nayem Hasan Munna for quite a long time. It is tough to find someone at his stage having too much interest in research. But he is an exceptional student who always take challenges for conducting empirical research. By evaluating some of his research, I found he has a good experience in lab analysis using different instruments, social data collection, and analysis through statistical software, and also has good knowledge on the social-technical approach of research. He is good at different research idea generation and formulating methodology in a problem-solving manner. His hard-working attitude and passion for learning make him an ideal candidate for learning from any world renounced university. His future plan is to contribute to Bangladesh’s environmental sector through scientific research which is very needful for the country.

I first met Md Nayem Hasan Munna when I joined as an Assistant Professor at the Department of Soil and Environmental Sciences, University of Barishal, Bangladesh in March 2015. After joining this department, I have taken two undergraduate courses in their batch. Later on, I switched to the Department of Coastal Studies and Disaster Management at the same University. I rarely come across real talents who stand out like Md Nayem Hasan Munna. He is an exceptional student who always takes challenges in conducting research. He had given an outstanding effort on several research projects of mine.
