Dr. Lal deep in discussion with Visiting Scholars at the International Scholar Research Exposition

November 7th — Dr.  Lal accompanied Visiting Scholars Xiaodan Gao, Fengkui Qian, Yingde Xu, Nour El Houda Abed and Karabi Pathak to the OSU’s Office of International Affairs Annual International Scholar Research Exposition. There, Drs. Gao and Qian presented posters of the research that they completed during their time as Visiting Scholars at C-MASC and received recognition for their work in the form of an official certificate and commendation from OSU’s President, Dr. Micheal Drake. They enjoyed the support they received from their collegues in C-MASC as well as delicious refreshments and the chance for great comeraderie as they shared the new insights they discovered at C-MASC.

Dr. Xiaodan Gao at the International Scholars Research ExpositionDr. Gao's reasearch involved soil organic-mineral complex and the stability of organic matter. She elaborates: "Long residence times of soil organic matter have been attributed to reactive mineral surface sites that adsorb organic species and cause inaccessibility due to physical isolation and chemical stabilization at the organic–mineral interface. This study explored the stabilization mechanism of mineral adsorbtion of organic matter in the mesoscale range of 1-1000 nm, from the perspective of the interactive forces between minerals and organic matter. The results suggested that adjusting soil internal forces is a feasible approach to regulating particle aggregation and promoting soil organic carbon stability."

 Dr. Fengkui Qian at the International Scholar Research ExpositionDr. Qian's research involved systems for basic farmland protection. He summarizes: "Under the pressure of urbanization and industrialization, the decreasing quantity and declining quality of farmland has attracted attention from the government and scholars to implement strict policies and pursue in-depth research for solutions in China. The land evaluation and site assessment (LESA) system, widely tested and applied for farmland protection in the U.S., is introduced in Lingyuan County, Liaoning Province, Northeast China. The final LESA scores illustrated comprehensive characteristics of farmland from suitability and compatibility. Therefore, the implementation of U.S. LESA system has proven to be more efficient and scientific in guaranteeing stability and permanence of farmland compared with ad hoc administrative interference in the basic farmland protection."
