MORAN-SANCHEZ, Gerardo et al. Residual soil due to extraction for brick and corn productivity. Rev. Mex. Cienc. Agríc [online]. 2025, vol.16, n.7, e3860.  Epub 13-Fev-2026. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v16i7.3860.

The extraction of large volumes of soil from agricultural land can have implications for crop production. The objective was to determine the area of agricultural land affected by the extraction of soil for brick manufacturing, the volume extracted, and the effect it has on corn yield in the locality of Santa María Zacatepec, Puebla, in 2022. To do this, plots were georeferenced and the volume extracted and income from sale were calculated; three sites were selected, one undisturbed (Undsoil), another that has undergone soil extraction for more than 12 years (Soildis12), and one that has undergone recent extraction (Soilrecdis) to evaluate the effect on corn yield. All the three sites were planted with the HS-2 corn hybrid to evaluate the response to the factors N, P2O5, K2O and population density integrated into a central composite, rotatable matrix with almost homogeneous information. In the locality, 25.2% of the area has been affected by soil extraction; on average, 33 354.4 m3 ha-1 is extracted, which generates a net income of 555 918.30 $ ha-1. Corn yield decreased by 79.1% in the remaining soil, with a loss of 52.20 cents per peso invested. The results show that it is possible to recover soils affected by extraction by applying organic matter.
