The Content Of The Article:

Crop rotation is an important aspect of gardening, especially for vegetable gardens. Since the growth of a crop depends largely on the nutrients from the soil, it will be preferable to group together the vegetables that have the same nutritional and displaced requirements in the garden so as to make the most of the reserves that are in this batch., that year.

Interests of rotation in the garden

The grouping of vegetables makes it easy to treat a plot with fertilizer, for example, for the vegetables that need it, and leave the soil untreated for those who do not require it.
It seems reasonable the following year to add fertilizer to the lot that did not receive it the previous year and to grow the plants that need it. "Reasonable" because if this soil did not receive its nutrient dose, it would soon lose its fertility and would be favorable for groups of plants whose requirements are even more modest.
Crop rotation is not just about linking plant needs to nutrients brought in by the soil. She also participates in the control of pests and diseases. If you put the same plant in the same place every year, it is likely that there will develop insects and diseases that prey on these plants. On the other hand, if the plants are transferred from one corner of the garden to another, any parasite born of the soil, as well as any disease, will remain where they are, without the plants which serve them as hosts: they will disappear or their population will be reduced. significantly before the host plant is re-planted at this location.

Rotation plan

The rotation plan can be done on a 3 or 4 year basis
There is usually one more plot compared to the groups that have to rotate, since some plants, such as rhubarb and artichokes, will require permanent implantation. Thus the 4th plot in a rotation over 3 years and the 5th in a rotation over 4 years are reserved for this type of plants and do not rotate with the rest.
The different possibilities of organization depend on what one wants to cultivate, on the space available, on how one can distribute these plants.
*The rotation plans, described here, are only suggestions. A winter evening can be pleasantly busy making your own plan.

Basic plan for a 3-year rotation

Basic plan for a 3-year rotation

ParcelOccupation of the plot
Zone 1The first plot will be composed of vegetables whose roots go deep and who like a rich soil. This includes beans, peas, leeks, celery, tomatoes, and squash, for example. This parcel will have to be turned twice and a lot of fertilizer or compost will be added to the soil.
Zone 2The second plot is reserved for cabbages with root tuber: cabbages, broccoli, Brussels sprouts. Organic fertilizers such as bone meal, dried blood, fishmeal, but not chemical fertilizers can be incorporated into the soil. You can also add a light touch of lime. The positioning of some members of this family poses a slight problem, especially rutabagas, turnips and kohlrabi. These vegetables are generally considered to be root vegetables since their roots are consumed, although they are very close to the cabbage family. They are therefore susceptible to the same diseases and also have the same requirements as cabbages. From a nutritional point of view, no matter where they are planted, but from the point of view of diseases it is dangerous to grow these different vegetables on the same plot 2 years in a row
Zone 3The third plot will be returned only once, and an advanced decaying fertilizer will be incorporated. This is for root vegetables (potatoes, parsnips, carrots, beets) and leafy greens (lettuce) as well as onions.
Zone 4The fourth plot is reserved for plants that require only very few transfers and are not part of the rotation. For example asparagus, rhubarb, artichokes and perennials.

Basic plan for a 4-year rotation

In principle, the 4-year rotation works in the same way as the 3-year rotation, except that the extra plot is attributed to more popular vegetables than the others. For example, it can be entirely devoted to potatoes or salads.
