Contribution
Dr. Jingna Liu’s research has made pivotal contributions to sustainable agriculture by optimizing the thermal drying process of solid digestate. Her work uncovered the fundamental mechanisms of nitrogen transformation and demonstrated that acidification prior to drying significantly reduces ammonia (NH₃) volatilization while enhancing plant-available nitrogen. This innovation boosts the fertilizer value of dried digestate, enabling its conversion into a nutrient-rich organic fertilizer. By improving nutrient retention and reducing dependency on synthetic fertilizers, her findings support circular agriculture, waste valorization, and improved environmental stewardship.
Research Focus
Dr. Liu’s research focuses on the recycling and utilization of agricultural solid waste, soil fertility enhancement, and nitrogen use efficiency. She investigates thermal drying and acidification processes to optimize nitrogen retention and reduce environmental emissions. Her work emphasizes the transformation of organic waste into effective fertilizers, offering solutions for improving soil health and reducing dependence on chemical inputs. Her studies provide scientific insights that support practical applications in sustainable farming systems.
