Protected agriculture helps improve agricultural productivity, but if the management is not adequate, it will increase the risk of affecting the environment and the profitability of crops. Therefore, in the municipality of Tetela de Ocampo, Puebla, in 2021, the chemical environment of the soil in greenhouses in the region that use fertigation was evaluated. To identify the details of agricultural activities, a questionnaire prepared specifically was applied to cooperating farmers, collecting a composite soil sample (five subsamples) per unit of production evaluated and uncultivated lands were included as a reference of the initial condition. The analysis of the samples was based on the NOM-021-RECNAT-2000 (NOM). The average annual yield of tomato is 31 ±7.6 kg m-2 and 87% of greenhouses have an area of less than 3 000 m2. They have technical assistance provided by companies and individuals, which include training courses and periodic soil analysis. In this study, excessive levels of all the chemical indicators established in the NOM were detected in the soil; nevertheless, the same fertilization program that has been carried out for several years in the region continues.
