Abstract

 

This study aimed to evaluate the effects of the application of swine wastewater treated in anaerobic digester(0, 100, 200, and 300 m3 ha-1) combined with nitrogen fertilization (doses of 0 and 100% of the recommendedculture of baby corn) on the edaphic macrofauna. Pitfall traps were used in the evaluation of the macrofauna and the collected organisms were classified at the taxonomic level by order. The diversity of the organisms was evaluated using the Shannon-Wiener, Pielou, and Group richness index. The results demonstrate that the use of swine wastewater increased the density of Hymenoptera significantly up to the dose of 200 mha-1,with a significant reduction in the dose of 300 m3 ha-1. The combined use of swine wastewater and 100% of the recommended chemical fertilization dose for the culture up to the limit of 100 mha-1 resulted in a significant increase in the density of the Coleoptera order, being positively influenced by these two factors. The swine wastewater dose of 200 mha-1 resulted in greater edaphic fauna diversity and richness.

 

Key words: Edaphic fauna, swine waste, water reutilization.
