WebD. S. Jenkinson mainly focuses on Soil water, Biomass, Soil organic matter, Environmental chemistry and Agronomy. His Soil water research integrates issues from Total organic carbon and Arable land. The concepts of his Biomass study are interwoven with issues in Fumigation, Biomass c and Incubation. WebBiomass carbon was determined using the method of Jenkinson & Powlson (1976). Incubated soils were subsampled and 30 g aliquots placed in Ehrlenmeyer flasks. These were then fumigated for 6 h with alcohol-free chloroform. After vacuum-removal of the chloroform, carbon dioxide traps containing potassium hydroxide
