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
recommended culture of baby corn) on the edaphic macrofauna. Pitfall traps were used in the
evaluation of the macrofauna and the collected organisms were classified atthe 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 m3 ha-1, with a significant reduction in the dose of 300
m3 ha-1. The combined use of swine wastewater and 100% of therecommended chemical fertilization
dose for the culture up to the limit of 100 m3 ha-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 m ha resulted in greater edaphic fauna diversity and richness.
Key words: Edaphic fauna, swine waste, water reutilization.
Swineproduction has increased year by year in the
Brazilian and the international market. Brazil was
responsible for 3.06% of the world production in 2008, a
total of 2.01 million tons, of which 625 thousand tons
were exported (USDA, 2008). Swine production has an
important place in the Brazilian economy, as it is carried
out in different degrees in all the states. However, 50% of
the production isconcentrated in the southern region
(Abipecs, 2008). Another aspect of this activity is the
large amount of waste it produces, which induces
producers to use this waste as an organic fertilizer.
However, not all producers have arable land large
enough for the proper usage of waste as water and

As a consequence, it is the buildup of nutrients (NO3, Cu,
Zn) and pathogens in soil, which can be carried, away by
either runoff or leaching and contaminate the water
sources (Baretta et al., 2003; Zhu et al., 2004). Therefore,
the use of swine wastewater has been intensively studied
all over the world (Suresh et al., 2009); on the other
hand, theinvestigation of variations of edaphic fauna in
response to the adoption of soil and culture management
in Brazil is still incipient.
According to Baretta et al. (2003), the use of organic
waste as fertilizer can affect the soil biota, mainly by
providing nutrients to organisms and modifying the soil
temperature and cover. Among the soil organisms,
macrofauna and invertebrates play a key rolein the
ecosystem as they occupy several trophic levels in the
soil food chain and affect the primary production both
directly and indirectly, by changes in soil structure and
