1. Soil compaction in areas of maize used for silage with the application of wastewater
RESUMO Durante dois anos consecutivos, a resistência mecânica do solo à penetração (RP) foi avaliada em áreas de produção de milho segunda safra para silagem. A retirada da parte aérea do milho no processo de silagem deixa o solo exposto, sujeito à compactação, o que pode comprometer o sistema plantio direto (SPD). Neste contexto, este trabalho t

2. CHEMICAL COMPOSITION OF SWINE WASTEWATER, SOIL, AND TIFTON 85 AFTER 8 YEARS OF APPLICATION
RESUMO O objetivo deste trabalho foi avaliar a composição química da água residuária da suinocultura (ARS) e efeito nos atributos químicos do solo e planta em um experimento de longa duração. A área destina-se a 8 anos a produção de feno de capim Tifton 85 (Cynodon spp.), com aplicação média anual de 360 m3 ha-1 dividida em 6 aplicações. Tamb

3. SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
ABSTRACT: The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are inserted. In this sense, the aim of this study was to assess the impact of swine wastewater and mineral fertilization application o

4. CORN FERTILIZATION USING SWINE WASTEWATER AND SOIL-WATER ENVIRONMENTAL QUALITY
ABSTRACT: Soil application of swine wastewater for nutrient cycling may represent a correct destination of these residues and reduction in production costs. However, when applied to soil, such residue may cause environmental impacts. This study aimed to analyze the chemical characteristics of the soil, corn, and leachate after successive swine wastewater app

5. SOIL MESO- AND MACROFAUNA IN TWO SOYBEAN CROPS AFTER SWINE WASTEWATER APPLICATION
ABSTRACT Hog raising generates a large amount of residues that is commonly discarded into the soil as fertilizer even with environmental risks. In this context, the aim of this study was to assess the application effects of different doses of swine wastewater (SW) associated with mineral fertilization on the abundance and diversity of organisms of soil meso-

6. Solid-Liquid Extraction with Low Temperature Purification Coupled with Gas Chromatography and Mass Spectrometry for Determination of Polychlorinated Biphenyls in Sewage Sludge
Sewage sludge is the residue produced by the wastewater treatment plants, which can be used as soil conditioner in agriculture. However, the current legislation recommends monitoring chemical contaminants such as polychlorinated biphenyls (PCBs). In this study, solid-liquid extraction with low temperature purification (SLE-LTP) was optimized and validated fo

7. DinÃmica de fÃsforo em manguezais impactados por Ãguas residuÃrias no Estado do CearÃ. / Dynamics of phosphorus in mangroves impacted by the state of CearÃ.
Recent studies demonstrated the efficacy of mangrove retaining nutrients and, in particular, the ability of the mineral component of the buffer in its high soil phosphorus levels. In general, the mangroves have been considered as important sinks of nutrients due to its high capacity purification of effluents. However, depending on the geochemical conditions

8. Reúso de efluente de esgoto sanitário anaeróbio e nitrificado em irrigação de roseiras / Reuse of anaerobic and nitrified wastewater effluents for irrigation of roses
Wastewater secondary treatment plants effluent may contain, yet, nutrients in amounts harmful to the environment. These effluents discharging can cause eutrophication in receiving waters, making it unsuitable for intended uses, such as provision for human consumption, leisure activities, etc. Besides the problem of eutrophication, there is the difficulty to

9. Estudo de uma metodologia para estimar a quantidade de carbono em amostras de solo utilizando espectroscopia de emissão óptica com plasma induzido por laser (LIBS) / Study of a methodology to estimate the carbon content in soil samples by laser induced breakdown spectroscopy (LIBS)
Soils are an important component in the biogeochemical cycle of carbon, storing about four times more carbon that biomass plants and nearly three times more than the atmosphere. Moreover, the carbon content is directly related on the capacity of water retention, fertility, among others properties. Thus, soil carbon quantification in field conditions is an im

10. Estudo geoquímico da bacia do ama e avaliação da qualidade de água
The quality of water in a drainage basin reflects the natural processes of a water catchment and the changes of environmental conditions reflect on physical and chemical water chemistry. The present work was realized in two drainages on Gama Catchment, Gama brook and Cedro stream, whose waters discharge into Paranoá Lake (Brasília, Federal District). The a

11. Caracterização física, química e ecotoxicológica de efluente da indústria de fabricação de explosivos
The production and use of nitroaromatic explosives have resulted in their dissemination into the environment, where their presence in waterways and soil represents an ecological and health hazard. The hazardous characteristics of these compounds need to be carefully studied, so that the impact of their discharge on the environment can be better evaluated. Th

12. Effects of sprinkler irrigation with treated sewage effluent, rich in sodium, on the chemical and physical properties of a typic hapludults cultivated with Tifton 85 grass. / Efeito da irrigação com efluente de esgoto tratado, rico em sódio, em propriedades químicas e físicas de um argissolo vermelho distrófico cultivado com capim-Tifton 85.
The natural scarcity of freshwater in the world has been aggravated by the pollution of the watercourses. The systems of treatment of sewage generate residues, such as treated sewage effluent, that when launched into rivers, has caused environmental impact. The use of the sewage effluent has been considered an important practice to minimize the negative impa
