Edible Bulbs - Allium

This is a link from a Netherlands Flower Bulb grower, apparently
' Nowadays all planting is done mechanically, using a 'fresh' field for every crop. By this crop-rotation we minimize the risk of diseases'

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.

California's central coast. Gilroy, CA, about ten miles north of me, calls

every year, but very little is grown there now. The area also used to be a
huge producer of cut flowers but that is all gone now too.
