Okay, found the source. They don't take into account different soils or factors such as increasingly variable weather or forest fires (which are becoming an increasingly significant issue in Canada for example).
As for soil quality, I don't know enough to give an informed comment. I know northern Canada has a lot of acidic muskeg which is completely unsuited for agriculture.

>We employed the LPJmL model (Bondeau et al., 2007) to compute the effects of climate change and CO2 fertilization on yields of major crops globally at a spatial resolution of 0.5°x0.5°. Yield simulations are based on process-based implementations of gross primary production, growth- and maintenance respiration, water-stress, and biomass allocation, dynamically computing the most suitable crop variety and growing period in each grid cell
