**1. Introduction**

For the intensive production of tomato, it must include the selection of the variety of interest, the germination of seeds in a certified nursery, the care of the seedlings in which it must include irrigation, temperature measurements, pest and disease control. And above all, take care of the height of the seedling, as it is a determining factor for good development in the field. Very tall seedlings present stress during planting in soil. Losses during the transplant process can reach 10–15%.

Before germinating the seeds of interest in the nursery, it is necessary to consider the preparation of the soil. During soil preparation, it is essential to carry out a physical–chemical analysis of the soil. This analysis should include: availability of primary and secondary macronutrients (ppm), organic matter (OM), EC, pH, bulk density (BD), and cation exchange capacity (CEC). Also, it will be necessary to carry out an analysis of the water quality. This analysis must include: pH, EC, the presence of bicarbonates (meq L−1), and take actions for its displacement with acids (HNO3, H2SO4, and H3PO4), to lower the pH, provide nitrogen, phosphorus, and remove salt from the irrigation system. With the soil analysis, amendments will be applied (t ha−1), application of OM (compost and vermicompost), agricultural plaster, and agricultural lime.

In addition, it is necessary to know and monitor the average temperature in each of the stages of the plant (germination – growth – flowering – fruiting). Temperature should include daytime and nighttime. This variable is extremely important because the success of production depends on it. In this chapter, we will address the importance of the available technologies for the intensive production of *Solanum lycopersicum* in soil.
