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.

“…Residues from swine (Caovilla et al, 2010;Sampaio et al, 2010) and cattle (Ayuke et al, 2011) farming, for being rich in nutrients, can be used as biofertilizers in agriculture. In liquid form, these residues are more efficient when disposed on soil surface, supplying plants with water and nutrients (Caovilla et al, 2010;Sampaio et al, 2010).…”

“…In liquid form, these residues are more efficient when disposed on soil surface, supplying plants with water and nutrients (Caovilla et al, 2010;Sampaio et al, 2010). On the other hand, these residues in liquid form require more-detailed studies on their destination in the soil, because they can cause diffuse pollution, which is difficult to detect and control.…”

Swine wastewater application is a practice that can become viable in agriculture, for minimizing fertilization costs and improving soil conditions. Therefore, it is essential to establish criteria that define appropriate application doses from the agronomic and environmental perspectives. The objective of this study was to evaluate the effects of swine wastewater doses associated with mineral fertilization on soybean nutritional status and physiological quality of seed. The experiment was conducted in the agricultural year of 2010/2011, using twenty-four drainage lysimeters in randomized block design in 4 x 2 factorial scheme, with four swine wastewater doses (0, 100, 200 and 300 m3 ha-1) applied before sowing, associated with presence and absence of mineral fertilization, in three replicates. Leaves at the flowering stage were collected for determinations of N, P, K+, Ca+2, Mg+2, Cu+2, Zn+2, Mn and Fe. Symptoms of toxicity and nutritional deficiency were observed in the crop. Furthermore, higher doses of swine wastewater caused lower physiological quality in soybean seeds.

“…Sustainable alternatives are needed, mainly in agriculture where water demand is much higher compared to industrial and urban sectors. Livestock wastewater application in farm irrigation contributes to the conservation of water resources, the long-term improvement of soil quality and the reduction of fertilization costs (SAMPAIO et al, 2010;MEDEIROS et al, 2011;MAGGI et al, 2013;BATISTA et al, 2014).…”

Swine wastewater (SW) application in agricultural soils may affect its microbial community in a long term. The objective of this study was to evaluate prospective changes in soil bacterial community after eight years continuous application of swine wastewater. The wastewater doses tested were 0; 100; 200 and 300 m 3 ha -1 , being applied from the beginning of the experiment and with or without recommended fertilization. Three soil samples were taken from each plot for determinations of basal respiration, microbial biomass and metabolic quotient. We also performed DGGE analysis and made a correlation between soil chemical conditions and microbial activity. Microbial community underwent significant structural changes from swine wastewater applications. Higher SW doses (200 and 300 m 3 ha -1 ) influenced significantly (p <0.05) and benefitted certain bacteria groups.
