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 EC50, 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.
目的通过标准化的生态毒理学试验，评价在农业地区施用堆肥和非堆肥禽畜粪便作为肥料对假丝虫(Folsomia candida)存活和繁殖的影响。方法在Entisol上施用堆肥和非堆肥禽窝，分别按0、10、20、40、60、80、100 t ha-1进行致死试验，按0、5、7.5、10、15、30、40、60 t ha-1进行繁殖试验。结果堆肥凋落物LC50值为76.45 t ha-1, EC50值为17.96 t ha-1。未堆肥家禽窝产中LC50为43.12t ha-1, EC50为19.36 t ha-1。结论未堆肥的凋落物毒性最高，强调有机肥在用作肥料前应进行稳定化处理。
