During a year away from studies in 1987-88, Dr. Paul Sanborn developed a successful grant proposal to the Science Council of BC (SCBC) to pursue a postdoctoral project with Dr. Tim Ballard in relation to sulphur-deficient soils in BC and prescribed fire. This project built on an existing broadcast burning study conducted by Macmillan Bloedel Ltd. near Port Alberni on Vancouver Island, led by Bill Beese (later at Vancouver Island University). Dr. Sanborn's work addressed sulphur forms and amounts in the soils at these sites, and the chemical processes influencing sulphur availability in relation to prescribed fire.

Only one part of this work was eventually published:
Sanborn, P.T. and T.M. Ballard. 1991. Combustion losses of sulphur from conifer foliage: Implications of chemical form and soil nitrogen status. Biogeochemistry 12: 129–134. https://doi.org/10.1007/BF00001810

The remainder of the work was documented in this Project Completion Report to SCBC, dated February 28, 1990, and entitled "Effects of Prescribed Fire on Sulphur in Forest Soils".
