Was Edible Bulbs - Allium, now crop rotation

I believe Janis Rucksans book "Burried Treasure" gives some information on
this subject, with advice for the crop rotation, and treatment regarding
various fungal and other problems. There was also a thread on the scottish
rock garden club forum last year discussing a black mould on the anthers of
muscari and scilla in which Janis gave significant information and pictures.
I have been advised by another nurseryman that control of "ink spot" on
reticulata Iris is only really achieved by replanting in fresh ground every
year, (though I do feel from observation of reticulata Iris, that Ink spot
primarily is brought about by irregular temperatures and periods of drought
during spring growth )

I would like to learn more about crop rotation protocols, what crops
follow
and how many years between bulb crops. In a garden situation, or a small
field how much 'space ' is needed separating crops, or are there trap
crops
to use as cover cropping for nematode, virus and root rot diseases.
Jan de Graff,......His practice was to lease land
that had never before grown lilies, and then grow a crop on them, for one
year
only. Next year, completely fresh ground.
