Welcome to my website which is about growing organic vegetable sustainably. My Garden Ecobeds use very little water and only homemade compost to maintain strong growth, and they produce lots of healthy nutritious organic food all year round. You can find out more about them on my page at http://jashxxxxxx.blogspot.com.au/p/wicking-beds-plus.html..............................................John Ashworth 27th November 2017.
Four Year Crop Rotation
Latest Update 3rd March 2018.
Four Year Crop Rotation (for annual vegetables).
Crop rotation reduces the
build up of plant pests in the soil.
borne pests target groups of
similar or related vegetables, but when the group moves to another bed,
the pests become dormant, and fall prey to their predators.
It takes 3 years for the crop to return to a given bed within the rotation in which time the pest has lost its potency and doesn't usually trouble its returned plant hosts.
In my 4 year crop rotation:-
Four different family groups of vegetables are grown separately in four garden Ecobeds.
In autumn each
family group is moved to the next bed in the rotation, and continues to be moved every year.
In a given bed, solanaceae are followed by light feeders, then by legumes, next by heavy feeders and finally solanaceae return to the bed (and so on).
The following schedule shows how the family groups move from bed to bed, year by year.
