“…They were defined based on the nitrogen concentration obtained from SWW physical-chemical analysis. The application rates are also similar to that used in the study of Meneghetti et al (2012), who defined SWW application rates based on nitrogen concentration in baby corn crop (0, 115, 230 and 345 m 3 ha -1 ). Besides the standard rates of 0, 100, 200 and 300 m 3 ha -1 , a treatment was carried out with the equivalent in available N (nitrate + nitrite + ammonia).…”

-The rate of swine wastewater application (SW) in agricultural production could result in the replacement of chemical fertilizers. However, SW destroys soil physical properties by decreasing pore bulk, which negatively affects both crop yield and development. In this context, this study aimed at monitoring the influence of swine wastewater as a cover fertilizer in maize and black oats in sequence on soil physical properties. Five application rates (0, 100, 200, 300 and 537 m 3 ha -1 equivalent to 0, 11.2, 22.3, 33.5 and 60 kg ha -1 N, respectively, based on the average nitrogen concentration in SW) were tested with four replications each. In the studied area, soil porosity, density, and water content, before maize sowing and at the end of the cycles of maize and black oats, were determined by the volumetric ring method. Data were submitted for regression analyses. There was a reduction in the macroporosity and total porosity of the soil when the SW application rate, before maize cultivation, was higher. The introduction of black oats helped to improve the physical quality of the soil and reduced the compaction of the surface layer from 0 to 15 cm and 100 to 300 m 3 ha -1 SW rates.Keywords: Swine manure.

ATRIBUTOS FÍSICOS DO SOLO APÓS APLICAÇÃO DE ÁGUA RESIDUÁRIA DE SUINOCULTURA APLICADA EM COBERTURA NA CULTURA DO MILHO E CULTIVOSEQUENCIAL DE AVEIA PRETA RESUMO -As taxas de aplicação de águas residuárias de suinocultura (ARS) utilizadas na produção agrícola podem substituir a adubação convencional, mas também podem prejudicar atributos físicos do solo pela diminuição do volume de poros, e consequentemente o rendimento e desenvolvimento das culturas. Neste contexto, o objetivo deste trabalho foi monitorar a influência do uso da água residuária de suinocultura como adubação de cobertura na cultura do milho e aveia preta em sequência sobre atributos físicos do solo. Cinco taxas de aplicação (0; 100; 200; 300 e 537 m 3 ha -1 sendo equivalentes a 0; 11,2; 22,3; 33,5 e 60 kg ha -1 de N, respectivamente, baseado na concentração média de N na ARS) foram testadas, com quatro repetições cada. No solo, foram determinados porosidade do solo, densidade, teor de água antes da semeadura do milho e ao final dos ciclos do milho e aveia preta, pelo método do anel volumétrico. Os dados foram submetidos a análises de regressão. Houve redução da macroporosidade e porosidade total do solo quanto maior a taxa de aplicação na cultura do milho. A introdução da aveia preta contribuiu para melhorar a qualidade física do solo e reduziu a compactação na camada superficial de 0-15 cm, para taxas de ARS de100 a 300 m 3 ha -1.

“…O uso desses resíduos na agricultura já é estudado e documentado (HERRMANN et al, 2016, PRIOR et al, 2015, MENEGHETTI et al, 2012MAGGI et al, 2013), sendo que a fertilização orgânica, isolada ou associada à adubação mineral, são tidas como alternativas economicamente viáveis (HERRMANN et al, 2016). Ainda, funcionando como como fonte de nutrientes ao sistema de produção agrícola torna se prática agrícola ambientalmente correta, fornecendo uma disposição final do efluente (HOMEM et al, 2014).…”

The system of intensive agricultural production, adopted by the majority of the producers, presents problems to the no tillage (SPD), mainly in the areas destined to the production of whole plant silage of maize. In this context, the objective of this work was to evaluate the fresh and dry mass of cover crops and soybean yield, under the cultivation of cover crops with and without swine wastewater (SWW). The work was developed in an agricultural property located in Matelândia, western region of Paraná. The experimental area consisted of seven management systems: soybean/silage/ black oats and turnips (SSOT); soybean/black oats and turnips (SOT); soybean/silage/chiseling + black oats and turnips (SSCOT); soybeans/silage and Brachiaria ruziziensis (SSB); soybean/ black oats and silage (SOS); soybean and silage (SS) and maize and soybean (MS), repeated for two consecutive years. In the treatments with SWW, 100 m 3 ha-1 year-1 were applied, divided in two equal doses: one on the corn and another on the cover plants. The experimental design was a randomized block design (RBD), with four repetitions per treatment, with four samples per repetitions. The application of SWW increased soybean yield as well as the production of fresh and dry mass of cover crops.

“…Many of these studies describe positive Maggi et al, 2011;Kessler et al, 2013b;Kessler et al, 2014) and negative (Doblinski et al, 2010;Sampaio et al, 2010;Meneghetti et al, 2012;Smanhotto et al, 2013;Tessaro et al, 2013) influences of SFW reuse on soil and its biota, plants, leachate and on runoff. Therefore, the challenge in wastewater management is to develop adequate application protocols, in order to minimize the polluting power of the activity and potentiate its efficiency as a liquid fertilizer.…”

A B S T R A C TIn the long run, swine wastewater can provide benefits to the soil-plant relationship, when its use is planned and the potential environmental impacts are monitored. The objective of this study was to investigate the effects of continuous application of swine wastewater, associated with mineral fertilization, after six years of management in no-tillage and crop rotation (14 production cycles), on the chemical conditions of the soil and the corn crop. The doses of wastewater were 0, 100, 200, 300 m 3 ha -1 during the cycle. The effects of the association between mineral fertilization at sowing and swine wastewater were evaluated simultaneously. Swine wastewater at the dose of 100 m 3 ha -1 promoted availability and absorption of P, K + , Mg 2+ and Zn 2+ without causing toxicity to plants or damage to the soil, constituting a viable, low-cost alternative of water reuse and fertilization for farmers. The nutrients N, P, K + and B must be complemented with mineral fertilization. Special attention should be directed to the accumulation of Zn 2+ in the soil along the time of swine wastewater application.Água residuária de suinocultura e adubação mineral no cultivo do milho R E S U M O Em longo prazo a água residuária da suinocultura pode oferecer benefícios à relação solo-planta, quando planejado o uso e monitorados possíveis impactos ambientais. O objetivo do trabalho foi investigar os efeitos da aplicação continuada de água residuária de suinocultura associada com adubação mineral após seis anos de manejo em plantio direto e sucessão de culturas (14 ciclos de produção) acerca das condições químicas do solo e da cultura do milho. As doses de água residuária foram 0, 100, 200, 300 m 3 ha -1 durante o ciclo. Simultaneamente foram avaliados os efeitos da associação de adubação mineral na semeadura com água residuária de suinocultura. A água residuária da suinocultura na dose de 100 m 3 ha -1 proporcionou disponibilidade e absorção de P, K + , Mg 2+ e Zn 2+ sem causar toxicidade às plantas ou danos ao solo constituindo viabilidade de reúso de água e fertilização alternativa de baixo custo ao produtor. Os nutrientes N, P, K + e B devem ser complementados com adubação mineral. Atenção especial deve ser direcionada ao acúmulo de Zn 2+ no solo, ao longo do tempo de aplicação de água residuária da suinocultura.
