Research & Resources

SoilVision® and SVOffice™ were developed based on research in unsaturated soils performed at the University of Saskatchewan in Saskatoon, SK, Canada. The most recent methods for analyzing unsaturated soils have been implemented in our software. We are committed to the continual improvement of our software, and will continue to make available our peer-reviewed research findings in conference and journal papers as we receive permission from publishers.
