The experiment was conducted in a greenhouse in a completely randomized design with five replicates, having as a substrate Humic Cambisol, which was characterized chemically and granulometrically, in possession of these results, the soil was previously corrected with lime and NPK. After 100 days of observation, it was analyzed the soil chemical variables (pH, H + Al, Al<sup>3+</sup>, Ca, Mg, P, K, Na, S, Cr<sup>3+</sup>, CO, SB, CEC, V, RAS and PST), the morphology plant [height (H), stem diameter (DC), the number of full sheets, the main root length (CR) and dry biomass], and the concentrations of N, P, K, Ca, Mg , S, Cr<sup>3+</sup> and Na in the plant. </span><span lang="EN-US">The tanning sludge was used as a nutritional supplement in doses of 0.0, 1.5, 3.0, 4.5 and 6.0 g kg<sup>-1</sup>. <span>The tanning sludge has potential as a corrective of soil acidity, with little significant increase in indicators of salinity, sodicity and Cr<sup>3+</sup> content available. </span>However, the use of sludge did not affect the morphological characteristics of seedlings ‘paricá’, but induced an increase in levels K and S in the shoot and Na and S in the root. <span>The greatest concentration of nutrients in ‘paricá’ were obtained with 6.0 g</span></span></span>
