N2 - Wastewater sludge, chemical fertilizer, and bovine manure were applied to a typical soil from the southeast part of Durango City, Mexico, in order to estimate and to compare the potential benefits in sorghum foliage (Sorghum vulgare Pers.). Concentrations of heavy metals were quantified from the aerial part of the plants and their roots, to detect if the plant absorbs the metals, because they cannot be degraded in the soil. Wastewater sludge comes from the wastewater plant of Durango City, and it is not impacted by industry; only domestic wastewaters are treated. A complete randomized block experimental design with five treatments and five repetitions and comparisons among treatment means were done using Tukey's method. Results show that production of dry matter is higher using wastewater sludge and bovine manure treatments, whereas lower production is obtained for chemical fertilizer and control treatments.
