ABSTRACT Poultry manure and mechanical management may influence the distribution of nutrients in the soil profile. The objective was to evaluate physical and chemical changes in a soil with palisade grass ( Brachiaria brizantha cv. Marandu) fertilized with doses of poultry manure with and without use of soil chiseling, after 180 days of application. The design was a randomized blocks with four replicates, in a 5 x 2 factorial arrangement with five doses of manure (0, 1.073, 2.074, 4.148 and 6.222 Mg ha-1), with and without soil chiseling at 0.20 m. Soil chiseling caused physical changes with an increase of macroporosity in the layer of 0-0.2 m and reduction in soil density and increase in macroporosity and total porosity in the layer of 0.2-0.4 m. With manure doses, pH in the layer of 0-0.1 m showed quadratic fit with maximum value of 7.2. The increases in Ca and Zn in the layer of 0-0.1 m were, respectively, 0.61 cmolc dm-3 and 2.99 mg dm-3. In the interaction of Dose x Management, without soil chiseling, K showed a linear fit and increased 1.39 times; while in the interaction of Dose x Management, with soil chiseling in the layers of 0.1-0.2 and 0.2-0.4 m, P increased by 8.10 and 3.95 mg dm-3, respectively. In the contrast between the dose zero and manure dose, there was significance for pH, Ca, P and Zn in the layer of 0-0.1 m.
