Please join us in celebrating the Inaugural Lecture of Professor Sami Ullah (Geography, Earth and Environmental Sciences). About the lecture: Nitrogen (N) availability modulates crop production in agriculture and carbon capture in natural ecosystems. Humans have perturbed the N cycle via excessive synthetic fertilizers input into soils. Crops available N is viewed as the “good” N. However, excessive input results in transforming the good N into the “grim” forms polluting air, water and soil. For example, agriculture contributes ~70% of the anthropogenic source nitrous oxide emission. Although referred to as the “laughing gas”, nitrous oxide emission into air is a grim matter contributing to global warming. Above all, parts of the N cycling processes are highly enigmatic to measure making it very difficult to find optimum pollution solutions. I will highlight latest methodological developments together with process understandings of soil N cycling in support of policy actions for constraining the impacts of the grim N forms!
