Retired in 1996, Les Henry is a professor emeritus at the University of Saskatchewan, a private consultant, and farmer. He is a renowned soils expert and in 2010 he released a lighthearted book about his passion for soils titled “Henry’s Handbook of Soil and Water”. On this episode of the SWAT Agronomy Podcast, Les reflects on his career milestones including conducting soil surveys, helping farmers solve problems like soil salinity, teaching and research he has done in both Canada and abroad, his 48 years of writing, his views on farmer-led research and extension and much much more.
