Abstract


Additions of poultry manure can promote improvements in the conditioning of the biological, physical and chemical properties of the soil. Thus, the present study aimed to evaluate soil chemical attributes through the superficial application of linear doses of chicken litter. The experimental design was a randomized block design, with 4 replicates and 7 treatments: T1: Witness (without application of avian bed), T2: 1 Mg ha-1, T3: 2 Mg ha-1, T4: 4 Mg ha-1, T5: 8 Mg ha-1, T6: 16 Mg ha-1, T7: 32 Mg ha-1 avian bed. The results indicate that the application of avian bed doses has an influence on K+ results, where intermediate doses as 12 and 18 ton ha-1 have higher results in potassium content in the analyzed soil. The doses of aviary bed alter the total organic carbon content. It can be said that higher doses of avian bed result in higher values of phosphorus and calcium. The calcium contents were higher than the magnesium content, potential acidity (H+ + Al3+) and Sulfur had a similar behavior to that of Calcium and Magnesium, a negative quadratic behavior. The values for pH measured did not vary greatly in relation to the doses of poultry bed applied and from the statistical data it was possible to determine that only pHCaCl2 had a significant difference. All other chemical attributes analyzed were not significantly influenced by the addition of the organic fertilizer when compared to the control, regardless of the application form in the soil.
