“…The result of treatment PS + SF was noteworthy, for being similar to PS100 and PS200 and higher Mafra et al (2014) in another study in the same experimental area. These authors reported that the combined treatment PS + SF resulted in a biomass yield similar to the treatments with highest PS rates and this yield was positively correlated with the TOC fixation rate in the soil (Mafra et al, 2014).…”

the use of pig slurry (Ps) as fertilizer can affect the soil quality and increase total stocks of soil organic carbon (tOC). However, the effects of Ps on tOC amount and forms in the soil are not fully understood, particularly in areas under no-tillage (nt). the purpose of this study was to determine tOC contents and stocks in the particulate (POC) and mineral-associated C fractions (MaC) of an Oxisol after nine years of maize-oat rotation under nt, with annual applications of Ps, soluble fertilizer and combined fertilization (pig slurry + soluble fertilizer). the experiment was initiated in 2001 in Campos novos, santa Catarina, with the following treatments: Ps at rates of 0 (without fertilization -Ps0); 25 (Ps25); 50 (Ps50); 100 (Ps100); and 200 m 3 ha -1 yr -1 (Ps200); fertilization with soluble fertilizer (sF); and mixed fertilization (Ps + sF). the tOC content was determined in samples of six soil layers to a depth of 40 cm, and the POC and MaC contents in four layers to a depth of 20 cm. From the rate of 50 m 3 ha -1 yr -1 and upwards, the soil tOC content and stock increased according to the Ps rates in the layers to a depth of 10 cm. the POC and MaC contents and stocks were higher in the surface layers, with a clear predominance of the second fraction, but a greater relative amplitude in the contents of the first fraction.

“…Specific recommendations include the development of critical P limits (Gatiboni et al, 2015) to obtain the expected benefits from the chemical, physical, and biological properties of the soil and subsequent crop yield (Mafra et al, 2014;Grave et al, 2015). The concept has been adopted that organic fertilizers help promote system sustainability and should not be regarded as a potential source of environmental pollutants (Lourenzi et al, 2013).…”

Organic fertilizers derived from poultry litter and pig slurry are alternatives to mineral fertilizers in increasing soil nutrient availability. The aim of this study was to evaluate soil response, through characterization of organic C and available N, P, and K contents, and corn yield response to increasing amounts of poultry litter, pig slurry, and mineral fertilizers in an integrated crop-livestock production system (ICL) from 2011 to 2013. The experimental design consisted of randomized blocks in a 4 × 3 + 1 factorial arrangement with four replicates. The treatments consisted of four types of fertilizer, two organic (poultry litter and pig slurry) and two mineral, balanced with the same amounts of N, P and K as the organic fertilizers, one of which corresponded to the levels in the pig slurry (M1) and the other to the levels in the poultry litter (M2) in combination with three .increasing application rates of N (100, 200, and 300 kg ha -1 N) and control without fertilizer. For two years after implementing the ICL system, the application of the different rates of N using organic (pig slurry and poultry litter) or mineral (M1 and M2) fertilizers increased corn yields and K and P availability in the soil; these results were accompanied by small changes in organic C and total N content. There are similar efficiencies between the treatments pairs (pig slurry/M1 and poultry litter/M2).

“…Under this scenario, environmental agencies have shown great concern, since when the soil bearing capacity is exhausted, this waste can cause a large amount of environmental damage (SEIDEL et al, 2010). In this regard, studies investigating water reuse in the environment have gained importance, and are usually related to physical-chemical changes in the soil (CAMPOS et al, 2012;LUCAS et al, 2013;MENEGHETTI et al, 2013;KESSLER et al, 2013;KESSLER et al, 2014;MAFRA et al, 2014), contamination of surface and groundwater (MAGGI et al,. 2011;BOLZANI, OLIVEIRA and LAUTENSCHLAGER 2012;MAGGI et al, 2013;CAPOANE et al, 2015), and the contribution to crop productivity (MENEGHETTI et al, 2012;CAMPOS et al, 2013).…”

-The structure of ant communities is of particular interest as a bioindicator, given their importance in environmental impact studies, as they present abundance and species richness, specialized taxa, wide geographical distribution, and are easily sampled, in addition to being sensitive to environmental changes. Therefore, the objective of this study was to evaluate the effects of wastewater application (0, 100, 200, and 300 m³ ha -¹ ) combined with nitrogen fertilization (0 and 100% of the recommended dose for the crop) on the myrmecofauna in plantations of minimilho in the municipality of Cascavel, PR. To evaluate the myrmecofauna, pitfall traps were installed and organisms were classified by gender. The Formicidae family exhibited increased density up to 200 m 3 ha -1 doses of pig farming wastewater, but no changes were observed in response to chemical fertilization. However, when sorted by gender at the taxonomic level, no significant effects were observed on the different groups, except for the Solenopsis genus following the use of 0 or 300 m 3 ha -1 pig farming wastewater.Keywords -edaphic fauna, edaphic ants, water reuse in agriculture.Resumo -A estrutura das comunidades de formigas é de particular interesse como bioindicadoras dada sua importância em estudos de impacto ambiental, uma vez que apresentam abundância e riqueza de espécies, táxons especializados, ampla distribuição geográfica, facilmente amostrada, além de serem sensíveis às mudanças ambientais. Considerando o exposto O objetivo do trabalho foi avaliar os efeitos da aplicação de água residuária da suinocultura (0, 100, 200 e 330 m³ ha -¹ ) combinada com adubação nitrogenada (0 e 100% da dose recomendada para a cultura) sobre a mirmecofauna em plantações de minimilho no município de Cascavel -PR.". Para a avaliação da mirmecofauna, foram instaladas armadilhas de queda sendo os organismos classificados ao nível de gênero. A família Formicidae teve densidade aumentada até a dose 200 m 3 ha -1 de água residuária da suinocultura, contudo sem mostrar alterações decorrentes da adubação química. No entanto, a classificação ao nível taxonômico de gênero demonstrou não existir efeitos significativos sobre os diferentes grupos, exceto para o gênero Solenopsis, quando utilizadas as doses de 0 e 300 m 3 ha -1 de água residuária da suinocultura.Palavras-chave -fauna edáfica, formigas edáficas, reuso de água na agricultura.
