Abstract This experiment assessed the effects of biosolids in the soil’s chemical and physical characteristics. Soil was mixed to a biosolid in a totally randomized design, within a 5× 4 factorial scheme: five doses of biosolid (0, 60, 120, 180, and 240 m3 ha-1) and four depths (0-0.10; 0.10-0.20; 0.20-0.30; 0.30-0.40 m). Soil was placed in 50 L-tubs imitating the soil profile. Doses of biosolid were added to the soil and samples were retrieved after 120 days. Biosolid tended towards acidification, with very low P and K rates. Nutrient leaching, such as Mg, increases microporosity and the reduction of soil macroporosity should be considered in high doses of biosolid.
