Long-term rotation trial, established 1980, Elora Research Station, Ontario
The focus of my research program is to develop agroecosystems that are both productive and sustainable. Over the years I have studied mechanisms underlying carbon cycling, nutrient cycling and yield of crop production systems as influenced by crop species, tillage system, crop rotation, and cover crops. I oversee several long-term trials, including a rotation trial (est 1980), tillage trial (est. 1976), and a nitrogen in maize trial (est 2008). In recent years, I have initiated research to examine the above mechanisms in bioenergy crop systems, particularly C4 perennial grass production. In 2008 I initiated a long-term perennial C4 grass for biomass trial (est 2008).
