My research over the last few years has focused on (i) understanding of water vapor sorption processes in soils, and the utilization of hygroscopic water content as a predictor of soil properties (clay content, surface area, CEC, Atterberg limits, etc.), (ii) the use of biochar, glacial rock flour, compost, and manure in temperate and tropical agricultural systems to improve soil fertility and crop yields, (iii) mechanisms of soil compaction recovery, and (iv) soil health
