Crop successions

When we grow several different vegetables in the garden, they do not all tend to have the same cultivation duration. For example, if we look at the planting calendar , we can see that a lettuce may be ready to harvest in 3 or 4 months while cabbage may take 6 or 7 months to be ready to harvest.

Also, combining short-cycle vegetables with long-cycle vegetables is done when the long-cycle vegetables will need more space during their maturity and by then we will have harvested the short-cycle ones, so we take advantage of the terrace without causing damage to development. of the plants.

Furthermore, to make better use of the space available for cultivation (especially in small orchards) and not leave the terraces at half their yield, we must plan the successions or rotations of the crops very well.

Crop rotation or succession

Crop rotation is a widely used technique in agroecology to maintain soil fertility, among other issues. What must be taken into account mainly is that the plants that we are growing successively are of different species, so they will have different needs and we will help to avoid the depletion of the land.

Each vegetable has its own chemical composition and needs nutrients in specific proportions during its life cycle. If we only grow the same plant in the same place for several years in a row, the plant will be absorbing the same nutrients while there will be others accumulating in the ground and not being used.

Other substances that the plant discards through its roots during metabolism also accumulate in the soil.

The consequences that most commonly happen when we do not practice crop rotation is that the chemical characteristics of the soil, the microflora, its pH, the permeability and even the texture change little by little. All these changes will be damaging more and more to the plant and it will be more difficult to produce fruits and it will be more vulnerable to pests and diseases.

In general, shallow root species are compatible with deeper root species, and species with dense foliage with other species with more limited foliage.

From what you are reading, you will imagine that it is important to write down in the garden notebook what vegetables you grow and with what others you are alternating them, in order to change in the rotations of the following years.
