Abstract

Purpose The objective was to evaluate the effect of the application of composted and non-composted poultry litter, as fertilizer in agricultural areas, on the survival and reproduction of the springtails (Folsomia candida) through standardized ecotoxicological tests.
Methods The treatments included in the application of composted and non-composted poultry litter on Entisol were in the following doses 0, 10, 20, 40, 60, 80, 100 t ha^-1, for the lethality test, and 0, 5, 7.5, 10, 15, 30, 40, 60 t ha^-1 for th­­e reproduction test.
Results For the composted litter, the LC₅₀ value was 76.45 t ha^-1 and for EC_50, it was 17.96 t ha^-1. For the non-composted poultry litter, the values of LC₅₀ was 43.12t ha^-1 and EC₅₀ value was 19.36 t ha^-1.
Conclusion The highest toxicity was observed in the non-composted litter, emphasizing the importance of stabilization of the organic compound before its use as fertilizer.
