Isotope Ratio Mass Spectrometer for Carbon Neutrality
Achieving carbon neutrality requires a multifaceted approach, where increasing soil carbon storage in agricultural lands plays a pivotal role. However, equally significant is the detailed analysis of soil morphology, as it influences carbon dynamics, sequestration potential, and the long-term stability of stored carbon. In our research, we emphasize the integration of these aspects by employing advanced analytical tools and methodologies. By utilizing state-of-the-art equipment specifically designed for soil carbon studies, we focus on tracing isotope-derived carbon to gain a comprehensive understanding of carbon sources, pathways, and transformations within agricultural soils. This approach not only allows us to investigate the quality and stability of soil organic carbon but also provides critical insights into optimizing soil management practices for enhanced carbon sequestration. Ultimately, our research aims to contribute to the successful realization of carbon-neutral agricultural systems, aligning with global efforts to mitigate climate change and ensure sustainable agricultural productivity.



BRL. for crop rhizosphere-sensitive next generation fertilizer
We aim to synthesize and evaluate fertilizers on a laboratory scale by utilizing activated sludge sourced from domestic wastewater, livestock manure, and food waste treatment facilities. Through processes such as acid hydrolysis, hydrothermal reactions, and hydrogen peroxide oxidation, we intend to transform the organic structure of activated sludge into a composite structure comprising recalcitrant organic matter and inorganic nutrients. Additionally, we will evaluate whether this transformed structure dissolves or disintegrates in response to root exudate components. The project focuses on identifying the structural characteristics of recalcitrant organic matter and the types of inorganic nutrients concentrated during the transformation processes. Furthermore, we aim to elucidate the physicochemical principles underlying the reactivity of these materials with root exudates. Specifically, we will interpret the interactions using concepts such as supramolecular complex disassembly, ligand exchange, surface modification, and competitive metal coordination. This approach not only aims to contribute to fertilizer development but also seeks to establish its operational principles, offering significant academic insights into the interplay between transformed organic-inorganic composites and plant root exudates.



Isotope Ratio Mass Spectrometer (IRMS-EA) for C/N cycle
This study aims to contribute to achieving carbon neutrality in the agricultural and life sciences sector by employing the "isotopic labeling" technique within plants. Through this approach, we seek to identify the sources, forms, and behaviors of carbon introduced into crops. The findings will provide critical insights into enhancing carbon sequestration and stability in soils. Ultimately, this research focuses on establishing sustainable farming practices that effectively increase soil carbon storage and contribute to long-term climate change mitigation. This study is dedicated to advancing the realization of carbon neutrality within the agricultural and life sciences sector by leveraging the innovative "isotopic labeling" technique applied to plants. This approach allows for a precise investigation into the sources, forms, and dynamic behaviors of carbon introduced into crops during their growth and interaction with the surrounding environment. By tracing the pathways of carbon from its initial input into the plant system through its subsequent incorporation into soils, the research seeks to uncover critical mechanisms that govern carbon dynamics in agricultural systems. A key focus of the study is to identify how carbon is sequestered in the soil, as well as to evaluate the factors influencing its stability over time. This knowledge is essential for addressing two major challenges in sustainable agriculture: reducing atmospheric carbon dioxide levels and enhancing the long-term storage of organic carbon in soils. By integrating isotopic analysis with soil-carbon interaction studies, this research aims to bridge the gap between plant-based carbon input and soil carbon storage, providing a deeper understanding of how agricultural practices can be optimized to maximize carbon retention.


Greenhouse gases(GHGs) emissions under horticulture crops
This study evaluates the greenhouse gas emissions from seven different crop types cultivated in the horticultural orchard at Kyungpook National University (KNU), with the overarching goal of addressing the role of horticulture in contributing to and mitigating global warming. By quantifying and analyzing the specific emissions associated with each crop type, the research aims to uncover patterns in greenhouse gas production, identifying factors such as crop physiology, soil interactions, and cultivation practices that influence emission levels. The study also investigates how crop-specific characteristics, including root morphology and nutrient use efficiency, may impact emissions and their subsequent effect on the environment. Beyond quantification, the research delves into sustainable agricultural practices, proposing tailored strategies to minimize emissions while maintaining crop productivity. By integrating these findings, the research seeks to provide actionable insights that can be applied to the horticultural sector to reduce its carbon footprint. The outcomes are expected to contribute significantly to the global efforts for climate change mitigation, offering practical solutions for sustainable horticulture and supporting the broader transition toward carbon neutrality in agriculture. Through this work, the study emphasizes the importance of targeted interventions in agricultural practices to balance productivity with environmental sustainability
