The intensive forage production for hay increases the risk of soil physical degradation and soil chiseling, with or without organic and mineral fertilization, could be alternatives to soil structural recovery. The objective of this study was to evaluate the soil chiseling and poultry litter fertilization effects on soil bulk density and porosity and Tifton 85 production. The experiment was conducted in a soil with a ten years hay production with Tifton 85. Significant changes in soil physical properties occurred only with chiseling, especially at 0.03-0.08m depth, keeping for at least nine months. The short period between the first cut and chiseling harmed the Tifton 85 production, with no difference between the soil management in the end of Bermuda grass growing season. The productivity was higher in treatments with nitrogen reapplication. Tifton 85 with poultry litter produced less dry matter than with mineral fertilizer on tfhe sum of four cuts of Bermuda grass
