Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?
The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...
