Through the fallow, the cultivation and rest cycles are combined. In this way it is sought that the soil does not lose its qualities. In general, during fallow the land is ara but it is not cultivated. This allows to eliminate weeds (which are used as compost) and increase the humidity of the Earth, favoring the recovery of minerals that are lost with cultivation.
It is important to highlight that the fallow land is not left abandoned or inactive, but is subjected to different labors that serve to help it recover its nutrients so that it can be sown in it during the following season.
