    The objective to evaluate the production of dry matter , crude protein and the chemical and physical soil for different levels of fertilization of pelleted poultry litter attributes . The test was conducted at the experimental farm of the University of North Paraná State - Campus Luiz Meneghel ( UENP / CLM ), the Bandeirantes - Paraná , the predominant soil in the area is the Oxisoil . The experimental design was randomized blocks , contained in five treatments with 0 , 5 , 10 , 15 and 20 Mg ha- 1 year-1- of pelleted poultry litter, with four replications , totaling 20 plots . Data were subjected to analysis of variance and regression parameters for the production of dry matter ( Mg ha- 1) and crude protein content . The physical and chemical soil variables was analyzed by Tukey test at 5% probability. The soil chemistry parameters was assessed levels of organic matter , potassium, phosphorus, calcium and magnesium from the soil and the soil physical attributes parameters evaluated were soil density, macro, micro, total porosity, percentage of aggregates and mechanical resistance soil penetration . The results showed: the of pelleted poultry litter can be considered an important source of nutrients to the grassy studied providing the increased production of dry matter, content of organic matter, exchangeable K and influence on soil aggregation.
