“…Nevertheless, this practice must be done with criteria. Frequent applications in association to high leve ls might influence the physical attributes of the soil, such as its density, structure and stability of aggregates, the aeration, draining and water retention (ERTHAL, et al 2010;SAMPAIO et al, 2010e SOUZA et al, 2010.…”

ABSTRACT:The feasibility of using sewage wastewater as a water and nutrient source for plants is an alternative to harness agricultural natural resource, observing its influence on the organic matter dynamics and soil energy. Our objective here was to evaluate the effects of applying different doses of effluent from a sewage treatment plant, in Janaúba -MG, Brazil, over the physical attributes of a soil grown with "Prata Anã" banana. From soil sample collection at depths of 0-20, 20-40, and 40-60 cm, we determined the following soil properties: soil density, total porosity, macroporosity, microporosity, organic matter, clay dispersed in water and stability of soil aggregate. The experimental design was in randomized blocks with four repetitions. Wastewater raising doses promoted increase in suspended solids, contributing to macroporosity reduction at 20-40 and 40-60 cm depths; as well as a reduction in organic matter within 0-20 cm layer. Clay dispersal was observed in the depths of 0-20 cm, being derived from an increase in sodium content. Concurrently, there was a reduction of soil aggregate stability. KEYWORDS:Musa spp, agricultural reuse of effluents, environmental sanitation, semi-arid. ATRIBUTOS FÍSICOS DO SOLO EM BANANAL FERTIRRIGADO COM ÁGUARESIDUÁRIA SANITÁRIA TRATADA RESUMO: A utilização de água residuária proveniente do tratamento de esgoto, como fonte hídrica e nutricional para as plantas, é uma alternativa para racionalizar o aproveitamento do recurso natural na agricultura, observando-se sua influência sobre a dinâmica da matéria e da energia no solo. O objetivo deste trabalho foi avaliar os efeitos da aplicação de diferentes doses de efluente da estação de tratamento de esgoto de Janaúba -MG, sobre os atributos físicos de um solo cultivado com banana 'Prata-Anã'. A partir da coleta de amostras de solo, nas profundidades de 0-20; 20-40 e 40-60 cm, foram avaliados os seguintes atributos: densidade do solo, porosidade total, macroporosidade, microporosidade, matéria orgânica, argila dispersa em água e a estabilidade de agregados do solo. O delineamento experimental foi o em blocos casualizados, com quatro repetições. O aumento das doses de água residuária sanitária tratada no solo promove: a) Incremento nos sólidos suspensos aportados ao solo, o que contribui para a redução da macroporosidade nas profundidades de 20-40 e 40-60 cm do solo; b) Redução da matéria orgânica na profundidade de 0-20 cm do solo; c) Aumento do aporte de sódio, o que determina a dispersão de argilas na profundidade de 0-20 cm, e d) Redução da estabilidade de agregados do solo.

“…The application of SW showed significant results for Ca levels, where the highest application rate corresponded to the smallest amount of Ca found (Figure 3). MENDONÇA & ROWELL (1994) reported that small changes in Ca 2+ levels in the soil can occur due to the low concentration of this element in the wastewater or its high retention by organic matter (CAOVILLA et al, 2010), since they did not observe such changes in the soil after application of SW in Dystroferric Red Latosol, grown with soybeans. These results also diverged from CASSOL et al (2012), who observed an increase in the Ca 2+ content in the layer of 0-2.5 cm when applied at a dose greater than or equal to 100 m 3 h -1 , SW and in the layer of 2.5-5 cm when the dose was of 200 m 3 h -1 .…”

Swine wastewater (SW) has high organic load, becoming an important source of macro and micronutrients to plants, promoting the improvement of soil quality and development in various cultures. However, when done without agronomic and environmental criteria, it can cause soil problems, nutrient leaching, water resource damage and plant toxicity. The objective of this study was to evaluate the soil chemical properties and the leachate in face of the association of swine wastewater and mineral fertilization (MF) in oat cultivation. An experiment in drainage lysimeter was carried out, using SW applications associated to MF or not, where treatments consisted of doses of 0, 100, 200 and 300 m 3 ha -1 with the absence or presence of MF, under field conditions. We concluded that swine wastewater provided significant increases in sodium, copper, zinc, and nitrite + nitrate as well as pH and calcium reductions in the soil; and in the leachate, significant increase in sodium. Moreover, the use of mineral fertilizer comprising nitrogen, phosphorus and potassium induced a significant increase in phosphorus, potassium and electrical conductivity and a significant reduction in magnesium in the soil; however, in the leachate, electrical conductivity was increased.

“…Técnica de valorização agronômica e ambiental, e consequentemente econômica, que associe tais fatores é a fertirrigação, prática que visa ao aproveitamento agrícola de águas residuárias geradas na criação de animais e em agroindústrias. Assim, q uando cuidadosamente planejado, o uso agrícola dessas águas residuárias pode concorrer, não apenas com a eliminação de um passivo ambiental, mas também com seu aproveitamento como fonte nutricional para culturas agrícolas (DOBLINSKI et al, 2010;SAMPAIO et al, 2010a;SAMPAIO et al, 2010b;CAOVILLA et al, 2010;PELISSARI et al, 2009;ANAMI et al, 2008;DAL BOSCO et al, 2008;ANAMI et al, 2007;SAMPAIO et al, 2007;FRIGO et al, 2006;CAOVILLA et al, 2005;SUSZEK et al, 2005).…”

RESUMO: O uso de água residuária em solo agrícola pode-se caracterizar como uma fonte alternativa de adubação, além de melhorar as condições edáficas do solo devido à matéria orgânica adicionada. Neste contexto, este trabalho teve por objetivo avaliar os efeitos na cultura do milho e em Latossolo Vermelho distroférrico típico, devido à aplicação de água residuária de suinocultura associada com adubação química. No experimento, utilizou-se de cinco doses de ARS (0; 112,5; 225; 337,5 e 450 m 3 ha -1 ) durante o ciclo do milho, combinadas com duas adubações químicas (50 e 75% da dose recomendada), para compor os respectivos tratamentos, com três repetições. Os parâmetros da cultura do milho avaliados foram: produtividade (PROD), altura de plantas (AP), teor de macronutrientes (N, P, K e Mg) e de micronutrientes (Fe, Zn, Cu e B). Os parâmetros de solo avaliados foram: conteúdo de matéria orgânica (MO), soma e saturação por bases (SB e V), pH e teores disponíveis de N, P, K, Cu, Zn, Fe e Mn. A partir dos resultados obtidos, concluiu-se que: na cultura do milho, a aplicação de água residuária da suinocultura é fator predominante no aumento da produtividade e na nutrição mineral em K, Mg, Fe, Cu e B, e insuficiente para N e P; no solo, de modo geral, a água residuária da suinocultura propiciou aumentos positivos nos parâmetros de P, Zn, Cu, pH e SB, negativos nos teores de K e Fe, e nenhum efeito nos parâmetros N, V, MO e Mn; os parâmetros P, Cu e Zn aumentaram significativamente os teores no solo ao longo do experimento, indicando a importância do fator tempo nesse tipo de estudo. PALAVRAS-CHAVE: reúso de água; resíduo animal, valorização agronômica. ESTUDY OF ASSOCIATION BETWEEN SWINE WASTEWATER AND CHEMICAL FERTILIZER IN CORN AND SOIL ABSTRACT:The use of wastewater in agricultural soil can be characterized as an alternative source of fertilizer, and improve soil conditions due to soil organic matter added. In this context, this study aimed to evaluate the effects on corn and in a Hapludox soil due to application of swine wastewater associated with chemical fertilizers. In the experiment, it was used five doses of swine wastewater (0, 112.5, 225, 337.5 and 450 m 3 ha -1 ) during the corn cycle, combined with two chemical fertilizer (50 and 75% of the recommended dose) to compose their treatments with three replicates. The parameters of maize crop were: productivity, plant height, macro nutrients (N, P, K and Mg) and micronutrients (Fe, Zn, Cu and B). The soil parameters were: organic matter, pH, N, P, K, sum of bases, base saturation, Cu, Zn, Fe and Mn. From the results it was concluded that: the culture of corn, the application of swine wastewater is the predominant factor in increasing productivity and mineral nutrition in K, Mg, Fe, Cu and B and insufficient for N and P; in the soil, generally, swine wastewater has positive increases in parameters of P, Zn, Cu, SB and pH, negative levels of K and Fe and no effect on the parameters N, V, MO and Mn; the time factor is extremely important in this type of study, for t...
