Why do we need crop rotation?
- Beneficial in minimising plant problems.
- Previous crops can benefit following crop.
Here is a basic three year rotation plan:
|Year One||Brassicas, Roots, Legumes|
|Year Two||Roots, Legumes, Brassicas|
|Year Three||Legumes, Brassicas, Roots|
Alternative growing methods:
not everything needs to be grown in the ground, Tubs / Raised beds / Hanging baskets / Growbags / Flower borders are all suitable alternatives.
most vegetables can be divided into specific groups and these are used when planning your crop rotation:
- Brassicas – Cabbages, Brussels Sprouts.
- Roots – Beetroots, Carrots.
- Legumes – Runner beans, Peas, French beans.
- Alliums – Onions, Shallots, Leeks
- Salads – Lettuce, Tomatoes.
- Permanent – Rhubarb, Asparagus, Globe Artichokes.
- Alliums can be incorporated within Legumes. Potatoes can be incorporated within Roots.
Each vegetable group tends to have its own nutritional requirement and the table below indicates the main requirements.
|BRASSICAS:||Lime acidic soils||General-purpose fertilizer before planting|
|ROOTS:||Don’t add manure||Don’t add lime||General-purpose fertilizer before planting|
|LEGUMES:||Add plenty of well-rotted manure / compost when digging||General-purpose fertilizer before planting|
Again there are specific terms that are associated with crop planning these are:
- Successional growing. Sow same crop at week/fortnightly intervals (Carrots / Lettuce).
- Intercropping: Fast growing crops between slow growers (Lettuce between Brassicas).
- Catch crop: Fast growing crop used in area before a required main crop is ready (Lettuce, Radishes, Spring onions).
