Abstract


he study of physico-chemical characterization of soils sustaining crops (8912 ha) of the Actopan-Ixmiquilpan zone is realised, which are irrigated with black waters. The physico-chemical characterization was realised by means of established determinations in NOM-021- RECNAT-2000 from the saturation extracts. The potential Z was moderate in these extracts and were correlated with physico-chemical parameters. From the calculated correlations it was possible to be determined that a correlation between physico-chemical properties of grounds like the pH and the potential Z exists (pZ). Also other correspondences between the values of pZ settle down, with the years of applications of the irrigation with black waters in these grounds. These studies provide the bases for later evaluations of probable affectations to the quality of grounds by the extensive use of irrigation with black waters.
