Earth and Soil of Jeju Island - Potential for Agriculture & Water Purification

For Earth & Soil of Jeju Island & Sustainable Agriculture, I researched "How Biochar Use Improves Soil Erosion Issues for Sustainable Agriculture in Jeju" under Sandile Mtetwa, focusing on Environmental Science and Earth & Planetary Science.

For Jeju Island Water Purification, I researched the "Effect of Mud Balls on Improving Water Quality in Sanji Stream" and conducted a year-long experiment to demonstrate their effectiveness.
