My research interests include soil acidity, the development of methods to estimate the acid-neutralising value of soil amendments, carbon sequestration, and drought stress management. I also worked on digital soil mapping and the development of digital soil information for site-specific management of soils.Currently, I am investigating the influence of soil amendments on pH and nutrient availability in acidic soils.
