ABSTRACT The objective of this study was to evaluate the productive and chemical characteristics of Marandu grass fertilized with poultry manure with or without the use of soil chiseling, during a period of 210 days. The experiment was conducted in a Dark-Red Latosol (Haplustox) of sandy texture, in a randomized block design with 4 replicates, in a 6 x 2 factorial scheme (0, 1.037, 2.074, 4.148, 6.222 t ha-1 of poultry manure and an additional treatment with chemical fertilizer based on 2.074 t ha-1, with and without soil chiseling). Grass-cutting management was performed between 95% of light interception by the canopy and the residual height of 0.15 m. The application of poultry manure resulted in an increase of forage production with higher number of... |

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.
