Crop rotation is the practice of
growing a series of dissimilar types of crops in the same space in sequential seasons to avoid the build-up of pathogens and
pests that often occurs when one species is continuously cropped. Crop rotation
also seeks to balance the fertility demands of various crops to avoid excessive
depletion of soil nutrients.
For the purpose of planning crop rotation, plants are grouped by
family (because they make similar demands
and have similar susceptibilities).
Here are some examples of
frequently grown crops, by plant family Cruciferae (HF)
heavy nitrogen feeders.
Pigeons are serious pests of brassicas. Protect with frames of netting or
fleece, and metal cages to keep them away from vulnerable crops.
Brassicas like fertile, well drained soil, but ensure moisture is maintained
and the ground is firm.
