Ben Zonneveld, with great respect: other reasons that bulbs in the 
Netherlands rapidly increase in size and number are the same elsewhere in 
the world:

-- sometimes the growing fields are healthy soil
-- sometimes the growing fields are sterilized
-- sometimes plants are minutely observed and selected for traits such as 
rapid production of offsets.
