**2. Soil preparation**

To achieve success in *S. lycopersicum* production megafactories, planning well in advance is essential. Among them, the preparation of the land, plot, or farm for cultivation stands out. Tracking and fallow by means of adequate machinery are determining factors for anchoring and root distribution. Once the land has been prepared, it will be necessary to carry out soil sampling. Soil subsamples can be taken in Zig-Zag or with another methodology according to the ground conditions. The variables of the physical–chemical analysis mentioned above will help to manage a good development of the crop in each growth stage [1]. Once the laboratory sends the results to the users, those responsible for the farm will take action to manage the soil. These actions may include applications of amendments, vermicompost, or mineral fertilizers (personal communication).
