“…In our study, doses of PS for maximum technical efficiency (MTE) were 106, 96 and 81 m 3 ha -1 of dry matter yields with 8,012, 12,843 and 8,494 kg ha -1 in the years 2010, 2011 and 2012, respectively. Crop response to high doses of PS was also observed by Ceretta et al (2005), who determined around 85 m 3 ha -1 as the MTE dose for the production of oat dry matter and corn grain in an Ultisol.…”

“…Grain yield was high due to the good soil fertility in the area and the favorable weather conditions (temperature and precipitation) during the course of this experiment. Ceretta et al (2005), Seidel et al (2010) and Lourenzi et al (2014) reported increases in corn grain yield under pig slurry application. In these experiments, the maximum grain yields were, respectively, 15, 10 and 11.6 t ha -1 , exceeding the yield of this study.…”

“…Several reports in the literature mention improvements in soil fertility and increases in crop yields when using pig slurry as organic fertilizer, without having gone through biodigestion (Ceretta et al, 2003;2005;Scherer et al, 2010;Lourenzi et al, 2014). However, successive applications of this organic fertilizer can promote excessive increases in P, Cu and Zn in soil, posing a potential contamination risk of soil and surface and subsurface water bodies Girotto et al, 2010;Veiga et al, 2012).…”

“…Embora esses dejetos possam ser fontes de nutrientes (Evans et al, 1977;Scherer & Baldissera, 1986;Ceretta et al, 2005), causam desequilíbrios quantitativos na oferta de nutrientes às plantas (Kirchmann, 1994;Hountin et al, 2000;Ceretta et al, 2003). Os dejetos podem ser considerados fertilizantes não balanceados, pois é praticamente impossível ajustar as diferenças entre as necessidades das plantas (quantitativa e temporalmente) e a oferta dos nutrientes pelo solo, ar e água.…”
