I have been studying the agricultural application of rock powders for 8 years and finished my Ph.D. about remineralizing soils the beginning of this year. Through my studies, experiments and exchange with farmers I gathered a comprehensive and nuanced knowledge about rock powders in agriculture. It became clear already many years ago, that the tropics have the highest need but also the highest potential for EW. Thus, together with my research team I am currently creating the most suitable measurement methodology for EW. Besides that, I evaluate the wider impact of using rock powders, like indirect CO2 emission reductions through reduced fertilizer usage and import.
