5.1. Indirect extrapolations
The stocking rates of colonies required can be estimated indirectly by using the pollination potential of individual foragers (i.e. seed set per flower visit; sections 2.2.2. and 2.2.3.) and extrapolating the number of foraging honey bees and colonies required to pollinate a crop (Goodwin et al., 2011). This presupposes our ability to reliably measure bee densities in the crop.
