Fertilization

I don't' mean to throw a spanner in the works, but how is it possible to
ever have a healthy soil if a field has been sterilized?  Once you wipe out
all of the beneficial micro-organisms, it always seems that it's the
pathogenic ones that come back first, making it necessary to get on the
chemical treadmill to have a saleable crop.  As an old organic grower, I've
found that if you maintain a healthy soil, the incidence of disease is much
less or non-existent.

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.
