1. Soil physical indicators of management systems in traditional agricultural areas under manure application
ABSTRACT Studies of the successive application of manure as fertilizer and its combined effect with long-term soil management systems are important to the identification of the interdependence of physical attributes. The aim of this study was to evaluate changes in the physical properties of a Rhodic Kandiudox under management systems employing successive ap

2. Phosphorus fractions in soil with a long history of organic waste and mineral fertilizer addition
ABSTRACT Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. In an experiment conduc

3. Odor from anaerobic digestion of swine slurry: influence of pH, temperature and organic loading
Farm slurry management from storage and/or treatment is the main source of odors from swine production, which are determined by factors such as operational variations (organic loading), cleaning of facilities and animal diet (pH) or environmental conditions (temperature). The aim of this study was to evaluate the influence of pH, temperature and organic load

4. PRODUÇÃO DE GRÃOS, MATÉRIA SECA E ACÚMULO DE NUTRIENTES EM CULTURAS SUBMETIDAS À ADUBAÇÃO ORGÂNICA E MINERA / PRODUCTION OF GRAIN, DRY MATTER AND NUTRIENT ACCUMULATION IN CROPS SUBMITTED TO ORGANIC AND MINERAL FERTILIZATION
In Brazil, one of the main activities on small farms is the creation of small animals. The waste produced in this activity can be used as an alternative fertilizer because it contains a number of chemicals readily available or after the process of mineralization can be absorbed by plants. However, the imbalanced composition of the organic fertilizers because

5. DEJETOS LÍQUIDOS DE SUÍNOS AFETAM A DECOMPOSIÇÃO DE PALHA DE AVEIA? / DOES PIG SLURRY AFFECT OAT STRAW DECOMPOSITION?
No sistema de plantio direto a aplicação dos dejetos de animais é feita na superfície do solo, sem incorporação. Nessa condição, é comum aplicar os dejetos sobre resíduos culturais de aveia, os quais variam quanto a sua relação C/N, em função do estádio em que a cultura é manejada. Poucos estudos foram conduzidos até o momento para avaliar o

6. NITROUS OXIDE EMISSION AND CARBON MINERALIZATION OF COVER CROPS AND PIG AND DAIRY CATTLE SLURRIES IN NOTILLAGE OF CASTOR BEAN / EMISSÃO DE ÓXIDO NITROSO E MINERALIZAÇÃO DO CARBONO DE PLANTAS DE COBERTURA E DE DEJETOS DE SUÍNOS E BOVINOS EM PLANTIO DIRETO DE MAMONA
The increase in the availability of nutrients to soil microorganisms, especially carbon (C) and nitrogen (N), through crop residues and animal slurries can increase dioxide carbon (CO2) and nitrous oxide (N2O) emissions to the atmosphere. In order, to evaluate this hypothesis, two studies in field conditions were conducted in a typic Hapludalf at experimenta

7. Listeria spp. e L. monocytogenes in the hot dog frankfurters production and consuption practices / Listeria spp. E Listeria monocytogenes NA PRODUÇÃO DE SALSICHAS TIPO HOT DOG E HÁBITOS DE CONSUMO
Listeria monocytogenes is a gram-positive bacterium, anaerobic facultative, that grows under refrigerator temperature and it can cause listeriosis in human and animals. It is widely distributed in the environment and it has been isolated from food of animal and vegetal origin that was associated to outbreaks of high lethality in many coutries. Thus, this bac

8. "Validation of an analytical methodology to the determination of sodium diclofenac in slurry samples from the water treatment station of Araraquara-SP" / "Validação da metodologia analítica para a determinação do diclofenaco sódico em amostras de esgoto da estação de tratamento da cidade de Araraquara-SP"
Os resíduos de fármacos presentes em matrizes ambientais têm sido foco em pesquisas no mundo todo. Este tema tem sido bastante discutido devido ao fato de que fármacos são freqüentemente encontrados em efluentes de estações de tratamento de esgotos (ETE´s), águas de abastecimento público e em outras matrizes ambientais, tais como solos, sedimentos

9. Caracterização, decomposição e biodisponibilidade de nitrogênio e fósforo de materiais orgânicos de origem animal e vegetal / Characterization, decomposition and mineralization of nitrogen and phosphorus of organic materials from animals and plants
This work presents results of a set of experiments carried out under laboratory, green house and field conditions regarding to the chemical and biochemical characterization of organic materials: raw animal manures, industrial residues, green manures and composts elaborated with coffee husk. With the objective to evaluated their decomposition, mineralization

10. Persistence of a Salmonella enterica Serovar Typhimurium DT12 Clone in a Piggery and in Agricultural Soil Amended with Salmonella-Contaminated Slurry
Prevalence of Salmonella enterica on a Danish pig farm presenting recurrent infections was investigated. A comparison of the pulsed-field gel electrophoresis patterns of fecal isolates from piggeries, waste slurry, and agricultural soil amended with Salmonella-contaminated animal waste (slurry) and subclinical isolates from the same farm (collected in 1996 a

11. Examination of Prepared Foods in Plastic Packages for Clostridium botulinum
The incidence of Clostridium botulinum organisms was determined in a variety of plastic-packaged “vulnerable” foods (food requiring little or no heating prior to consumption). A total of 113 foods were examined by use of an enrichment recovery procedure followed by toxin testing in animals. Results of the survey indicate that the incidence of C. botulinu

12. Analysis of Escherichia coli O157:H7 Survival in Ovine or Bovine Manure and Manure Slurry
Farm animal manure or manure slurry may disseminate, transmit, or propagate Escherichia coli O157:H7. In this study, the survival and growth of E. coli O157:H7 in ovine or bovine feces under various experimental and environmental conditions were determined. A manure pile collected from experimentally inoculated sheep was incubated outside under fluctuating e
