“…The maximal concentration of K in the percolated was 59.0 kg ha -1 (ALT4), presenting a significant effect when compared to the 23.6 kg ha -1 removed in the percolate after application of the AQT0 treatment. These results were superior to those found by Brito et al (2005), in which were observed concentrations of 15.1 kg ha -1 of K in the percolation of soil columns submitted to 700 m 3 ha -1 of vinasse, and Maggi et al (2013) that observed the presence of 4.7 kg ha -1 of K in percolate of 27 lysimeters submitted to dosages of 300 m 3 ha -1 of swine wastewater (SSW).…”

ABSTRACT:The objective of this study was to evaluate the quality of the percolate in soil columns cultivated with Tiffon-grass 85 under different wastewater rates from swine slaughterhouse and dairy. The experiment was conducted at the Department of Engineering at the Federal University of Lavras, in PVC columns with 0.30 m of diameter and 1.2 m deep, filled with Dark Red Latosol cultivated with Tifton-grass 85. The treatments consisted of a (AQT0) control with recommended chemical fertilization for Tifton-grass 85 (300 kg ha -1 year -1 of N), and four doses of SSW and DPW (100, 200, 300 and 400% of the recommendation) in a CRD with 3 replications. The samples of percolated were collected and characterized weekly. The treatments of highest dosage have obtained COD, after 120 days, of 47.7 mg L -1 (AAT3) and 38.6 mg L -1 (AAT4). Although nitrate concentrations were elevated on the earlier months, the greater assimilation of nutrients by the Tifton-grass 85 and the reduction of the mineralization of organic material resulted in lower nitrate concentrations of 10 mg L -1 .

“…Rajesh et al (2009) found an increase in soil pH (7.90 to 8.07) when applying oil-refinery effluent at various time intervals; according to the authors, this result was due to the alkaline characteristics of the effluent and the high concentrations of soluble salts. In evaluating the effect on the soil of applications of wastewater from pig farming, Cabral et al (2011) found no significant variation in pH values at the applied effluent doses; results which were confirmed by Maggi et al (2013).…”

. As aplicações ocorreram em intervalos de 20 dias utilizando-se um sistema de irrigação localizada com gotejadores de vazão nominal de 4 L h -1 espaçados em 0,40 m. As doses de vinhaça aplicadas foram calculadas, seguindo recomendações da norma CETESB P4.231, de modo que o tratamento T4 suprisse a demanda por potássio do abacaxizeiro. A coleta da solução foi realizada por meio de extratores de cápsulas porosas após 30; 120 e 210 dias do início da aplicação da vinhaça e verificou-se que o aumento dos volumes de níveis aplicados resultou em maiores valores de Condutividade elétrica do solo (CEs) e concentrações de potássio (K) e nitrato (NO 3-), com maiores valores obtidos na camada de 0,20 m. Os resultados revelaram que o pH diminuiu à medida em que se aumentavam os volumes de vinhaça aplicados.Palavras-chave: Efluentes. Reuso de água. Lixiviação.

RESUMO:O objetivo deste trabalho foi avaliar as características bromatológicas de uma pastagem de Brachiaria decumbens fertilizada com dejetos suínos, bem como avaliar as alterações que a utilização desse dejeto causa em alguns atributos químicos do solo. O delineamento foi em blocos casualizados, com seis tratamentos: T1: ausência de adubação mineral e orgânica (tratamento--controle); T2 apenas com adubação mineral; T3, T4 e T5 com diferentes doses de dejetos líquidos de suínos (respectivamente ao equivalente a 60; 120 e 180 m 3 por hectare), e T6 tratamento organomineral (120 m 3 por hectare) de dejetos líquidos de suínos, com adição de fertilizante mineral). Observou-se que houve incremento em produtividade de massa seca (MS). O uso de dejetos de suínos resultou em aumento significativo nos valores de proteína bruta das plantas de Brachiaria decumbens, não tendo a mesma eficiência para os valores de fibra em detergente neutro (FDN), fibra em detergente ácido (FDA) e lignina. A aplicação de dejetos suínos aumentou os teores de N, P, Ca e Mg nas plantas de Brachiaria decumbens. Não foram constatadas alterações quando comparados os valores de pH e matéria orgânica do solo. Os dejetos líquidos de suínos podem ser utilizados para fornecer macronutrientes para as forrageiras, desde que com aplicação controlada. PALAVRAS-CHAVE:atributos do solo, fertilização de pastagem, resíduos orgânicos, suinocultura. FERTILIZATION WITH SWINE WASTE MANURE : THE INFLUENCE OF CHEMICAL CHARACTERISTICS IN Brachiaria decumbens AND CHANGES IN THE SOILABSTRACT: The objective of this study was to evaluate the qualitative characteristics of Brachiaria decumbens pastures fertilized with swine manure, as well as evaluating the changes that the utilization of manure causes in some soil chemical properties. The design was randomized blocks with six treatments: T1: absence of mineral and organic fertilizer (control ), T2 : with mineral fertilizer only, T3, T4 and T5 with different doses of swine slurry (respectively equivalent to 60 , 120 and 180 m 3 ha -1 ), T6 organic and mineral mixed treatment (120 m 3 per hectare) of swine slurry added with mineral fertilizer). It was observed that there was an increase in productivity dry matter (DM). The use of swine manure resulted in significant increase in crude protein values of Brachiaria decumbens plants, do not having the same efficiency for Neutral detergent Fiber (NDF), Acid detergent Fiber (ADF) and lignin. The application of manure increased the content of N, P, Ca, Mg in Brachiaria decumbens plants. No changes were observed when comparing the values of pH and soil organic matter. Liquid swine manure can be used to provide macronutrients for the fodder, since with controlled application.
