“…Treatments consisted of two doses (0.2 and 0.3 L/container) of raw swine wastewater (SW) with or without tetracycline (TC), chlortetracycline (CTC), and doxycycline (DC). The doses of SW followed the studies of Pereira et al (2016). The concentrations of the antibiotics tested in the experiment were determined based on values found by Jindal et al (2006), Zhou et al (2009), and Zilles et al (2005) in SW.…”

The objective of this study was to evaluate the influence of tetracyclines associated with swine wastewater on the enzymatic activity of soil over time, in relation to the biogeochemical cycle of the nutrients during two seasons of the year. The experiment was carried out in soil-containing pots that received two successive applications of swine wastewater treatments, in the summer and autumn seasons, corresponding to two experimental periods. The swine wastewater was applied in doses of 0.2 and 0.3 L, with or without tetracycline, chlortetracycline, and doxycycline. Soil samples were collected at 2, 4, 8, 15, 30, 45, and 75 days after treatment application to determine the activities of the enzymes dehydrogenase, β-glucosidase, acid phosphatase, and urease. During both experimental periods, there was an increase in the activities of all enzymes in the presence of swine wastewater. However, these activities decreased in the presence of the applied antibiotics. The observation of enzyme activity over time facilitated construction of longitudinal predictive models, which described the activity of enzymes over time. Our findings indicate that swine wastewater treatments led to a reduction in the bioavailability of nutrients, thereby reducing soil quality and fertility.

“…A high level of Cu and Zn can be associated with an abundance of these elements in the basalt, which is the parental material of the soils in the area studied (Formentini et al, 2015). However, when using LSM these levels increased significantly, raising concerns about soil contamination, as well as the transfer of these elements to the watercourses nearby (Formentini et al, 2015;Broetto et al, 2014;Pereira et al, 2016;De Conti et al, 2016;Oliveira et al, 2017). Therefore, the monitoring of these areas of continuous use of LSM is fundamental to properly planned LSM application (i.e., reducing the applied volume or even ceasing the application) in a way that avoids problems related to contamination of heavy metals in pasture areas as well as its transfer within the trophic chain of the production system.…”

Chemical and physical properties of soil can be altered with the successive application of liquid swine manure (LSM), also known as slurry. Therefore, monitoring the impact of LSM is essential to an assessment of the potential agronomic and environmental benefits and risks associated with management practices. The aim of this study was to evaluate the effects of LSM on the chemical and physical attributes of soil under pasture (Cynodon spp.), located in southern Brazil. Four areas were sampled: three areas cultivated with Cynodon spp. pasture with successive applications of 200 m 3 ha -1 y -1 of LSM for three, eight and 15 years; and untreated native forest as a reference. The soil attributes evaluated were: organic carbon (OC), active (pH water) and potential acidity (H + Al + 3 ), nutrient availability (i.e., P, K, Ca, Mg, Cu and Zn), soil bulk density, macro, micro and total porosity. Successive applications of LSM on pasture reduced soil active acidity, and increased the soil organic C and plant-available N, P, Ca, Mg, Cu and Zn contents. These effects were more intense with time and in the shallowest layers, i.e. 0-10 cm.Excessive increases in P, Cu and Zn in the soil should be carefully monitored to minimize the contamination risks to soil, ground and surface waters. Soil physical attribute changes were more associated with land use (pasture versus native forest) than LSM use, and LSM applications induced slight improvements in the soil structural quality over time.

“…Além do pH, de 7,25, caracterizaram a ARS considerando a condutividade elétrica, que foi de 4,15 mS cm -1 e elementos como nitrogênio, fósforo, potássio, cálcio, magnésio e enxofre. Pereira et al (2016) aplicaram ARS com adição de adubação mineral em solo com plantio de milho nas proporções de dosagem de fertirrigação de 0, 100, 200, 300 m 3 ha -1 , sendo que a de 100 m 3 ha -1 , segundo eles, foi a taxa ideal, tanto para absorção da cultura, quanto à conservação do solo. Além disso, caracterizaram a água residuária, e obtiveram pH de 7,6 e DQO de 2160 mg L -1 .…”

A produção agrícola e a criação de animais (rebanho, abate e produção de carne) são importantes setores econômicos do Brasil, resultando na geração de efluentes com alta carga orgânica, oriundos das lavagens dos currais, por exemplo. O despejo indevido em corpos hídricos ou solos, pelo lançamento de efluentes ou pela irrigação, pode comprometer a qualidade desses recursos, visto que existem padrões de lançamento desse residual estabelecendo limites máximos de concentrações de vários compostos. Assim, o trabalho analisou alguns casos de fertirrigação da literatura e apontou o que vem sendo feito na agroindústria em questão, considerando visitas técnicas, entrevistas com o gestor e proprietário, como também algumas análises físico-químicas do efluente, que foram de 978,4 ± 69,9 mg L-1 de DBO, 1948,2 ± 222,8 mg L-1 de DQO e pH 6,8 ± 0,09. Constatou-se que o uso da fertirrigação, mesmo com vários benefícios, pode causar danos ao solo e à água, pois necessita-se considerar as análises físico-químicas do efluente e do solo irrigado com o efluente. Portanto, para assegurar a efetividade dessa prática na agroindústria, é imprescindível realizar análises do solo a ser fertirrigado para diagnosticar sua atual condição, tanto em termos de possível acúmulo ou lixiviação dos nutrientes.
