That gives 72391.68 acres! Ratnieks measured bees going 7 miles (11km) for heather. Surely they will do that for OSR as well. So, when the public require to be reassured that there is no GM source of honey, even though we are not talking organic, then each location requires a minimum of 50 sq miles (120 sq km).
