1. Electrical Conductivity and Chemical Composition of Soil Solution: Comparison of Solution Samplers in Tropical Soils
ABSTRACT Soil solution samplers may have the same working principle, but they differ in relation to chemical and physical characteristics, cost and handling, and these aspects exert influence on the chemical composition of the soil solution obtained. This study was carried out to evaluate, over time, the chemical composition of solutions extracted by Suolo A

2. 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

3. Efeitos da aplicação de glifosato na química de solos alagados / Effects of glyphosate on the chemistry of flooded soils
This study aimed to evaluate the effects of the herbicide glyphosate in the chemistry of the flooded soils in two humid tropical areas included in the Brazilian savanna, observing these effects in the solid fraction and the soil solution. We used soil from an area of lowland irrigated rice cultivation and a preserved area of path, constituting, respectively,

4. Relações entre nutrientes na fase sólida e solução de um latossolo durante o primeiro ano nos sistemas plantio direto e convencional / Relationship between nutrients in solid phase and soil solution of a “latossolo” (oxisol) in the first year of no-tillage and conventional systems
Somente a análise dos nutrientes da fase sólida pode não representar a disponibilidade de nutrientes porque não considera a sua relação com a solução do solo. Realizouse um trabalho visando a estudar a relação entre nutrientes na fase sólida e na solução de um Latossolo durante o primeiro ano da instalação dos sistemas plantio direto e convenc

5. Environmentally induced cracking of API grade steel in near-neutral pH soil
Environmentally induced cracking of pipeline steels in contact with soil have been investigated. Different soils were prepared in order to determine their physical, chemical and bacteriological characteristics. Slow strain rate testing was carried out by using electrolytes obtained from soil samples and NS4 standard solution. Stress vs. strain curves of API

6. SIMULATION OF THE VERTICAL TRANSPORT OF ZINC, LEAD AND COPPER IN CONTAMINATED SOILS / SIMULAÇÃO DO TRANSPORTE VERTICAL DE ZINCO, CHUMBO E COBRE EM SOLOS CONTAMINADOS
The environmental contamination by metallic trace elements is a problem that is getting worse around the world due to the growth and the technologic development of the humanity. Among the main sources of this kind of contamination are the atmospheric deposition of particles in soils located around industrial complexes and the prolonged and concentrated appli

7. Avaliação da co-disposição do lodo de tanques sépticos e fração orgânica de resíduos sólidos domiciliares em reatores anaeróbios / Evaluation of co-disposal of sludge from septic tanks and organic fraction of domestic solid waste in anaerobic reactors
Despite being an emerging country, unfortunately the sanitary situation of Brazil is quite precarious. Only 52.2% of the 5,507 brazilian municipalities have some type of sanitary service (IBGE, 2000). In this alarming scenario, individual solutions are gaining more importance. The adoption of septic tanks as an alternative to the solution of the sewage becom

8. ASPECTOS NUTRICIONAIS DE UM SISTEMA AGROFLORESTAL COM EUCALIPTO NO SUL DO RIO GRANDE DO SUL, BRASIL / NUTRITIONAL ASPECTS IN AN AGROFORESTRY SYSTEM WITH EUCALYPTUS IN SOUTH BRAZIL
This study was conducted at an experimental area at Aroeira Farm, belonging to Votorantim Celulose e Papel company, under the geographic coordinates 31 45 50.7 S e 53 50 34.9 W, located in Candiota county. In the area there is an experimental field, where some production factors involved in an agroflorestry system are being monitored, with four different tre

9. Estudo comparativo da aplicaÃÃo de vinhaÃa tratada e in natura em solos sob cultivo de cana-de-aÃÃcar
Brazil is the world leader in sugarcane plantation. Its economical exploration generates residues, standing out the vinasse. Due to the problems of ecological and social order caused by the vinasse, the most plausible solution for its disposition is the application to the soil as fertilizer. However, that application requests studies to guide the management

Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Use of filer of quarries in the metropolitan area of Goiania flexible pavements in urban [manuscript]: assessment technical and socio-environmental / Aproveitamento de filer de pedreiras da região metropolitana de Goiânia em pavimentos flexíveis urbanos [manuscrito]: avaliação técnica e sócio-ambiental
The generation of industrial waste has been the object of increasing attention in the field of Science and Technology because of the problems which arise when it is stored and inadequately disposed of. This can have negative consequences for the worker, the company and for the neighboring population. In addition it can generate liabilities for the environmen

12. Isolamento e identificação de Klebsiella de solo de cerrado e o uso de suas enzimas para modificação química de fungicidas / Isolation and identification of Klebsiella in cerrado soil and its use of enzymes for chemical modification of fungicides
In this research, open ground samples (Brazilian Savannah Cerrado) proceeding from treated cultures of soy with Opera (epoxiconazol and piraclostrobin) had been used as source of resistant microorganisms to fungicide. The sample were collected in July 2006, in three points of planted area and two depths, 0 to 20 cm, and from 80 cm to 1m, next to the state hi
