Biografi

Dedicated researcher with experience in soil science, sustainable agriculture, and climate change adaptation. Academic journey includes a Ph.D. and postdoctoral research focused on soil organic matter stabilization and carbon sequestration in agriculture. Led and coordinated multiple research projects, utilizing advanced techniques such as isotope labeling and synchrotron-based methods, and collaborated with esteemed professors and international research teams.

Work spans various global initiatives, including projects on organic waste management, diversified cropping systems, and no-tillage practices in tropical and subtropical regions. Contributed to educational efforts by developing teaching materials, assisting students, and writing accessible content for broader audiences.

Deeply interested in multidisciplinary soil science research, particularly focusing on soil structure and the persistence of organic matter. Research interests encompass the functionality of soil organic matter in both agricultural and natural systems, primarily focusing on mechanisms for its persistence through organo-mineral associations.

Sammendrag

Soils are the third largest carbon pool on Earth and play a crucial role in mitigating climate change. Therefore, understanding and predicting soil carbon sequestration is of major interest to mitigate climate change globally, especially in countries with strong agricultural backgrounds. In this study, we used a new database composed of 5029 samples collected up to 1-meter depth in three biomes that are most representative of agriculture, Pampas (Prairie), Cerrados (Savanna), and Atlantic Forest (Forest), to explore soil organic carbon (SOC) stocks and its environmental drivers. The Cerrado (Savanna) biome was the only one where croplands presented higher SOC stocks than native vegetation (Native vegetation 121.23 Mg/ha and croplands 127.85 Mg/ha or 5 % higher). From the tested models, the Random Forest outperformed the others, achieving an R2 of 0.64 for croplands and 0.56 for native vegetation. The accuracy of the models varied with soil depth, showing better predictions in shallow layers for croplands and deeper layers for native vegetation. Our results highlight the importance of clay content, precipitation, net primary production (NPP), and temperature as key predictors for soil carbon stocks in the studied biomes. The findings emphasize the importance of protecting the surface layers, especially in the Cerrado biome, to enhance SOC stocks and promote sustainable land management practices. Moreover, the results provide valuable insights for the development of nature-based carbon markets and suggest potential strategies for climate change mitigation. Enhancing our understanding of SOC dynamics and adopting precise environmental predictors will contribute to the formulation of targeted soil management strategies and accelerate progress toward achieving climate goals.

Sinograin III: Smart agricultural technology and waste-made biochar for food security, reduction of greenhouse gas (GHG) emission, and bio-and circular economy


The Sinograin III project’s overall objective is to contribute to the UN SDGs by widely implementing precision agriculture technologies and application of “waste-to-value” biochar products to achieve sustainable food production with minimized GHG emission, improve soil fertility and promote green growth/zero waste in modern agriculture in China.
