1. Humic Substances and Chemical Properties of an Acrisol Amended with Vermicomposted Vegetal and Animal Residues
ABSTRACT Vermicomposted vegetal and animal residues are rich in nutrients and humic substances and thus can be applied to the soil as a source of functionalized organic matter (OM) and as an alternative to chemical fertilizers. In Southern Brazil, many animal and vegetal residues are easily accessible. Therefore, this study aimed to evaluate alterations in s

2. Edaphic macrofauna in degradation of animal and vegetable residues
Resumo Este estudo objetivou avaliar a capacidade de degradar a matéria orgânica pela macrofauna edáfica (minhocas), a relação carbono/nitrogênio (C/N) e o potencial hidrogeniônico (pH), durante o processo da vermicompostagem em diferentes resíduos orgânicos. Os tratamentos foram constituídos por resíduos orgânicos de origem animal (esterco bovi

3. 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

4. Crude glycerin in anaerobic co-digestion of dairy cattle manure increases methane production
ABSTRACT Anaerobic digestion of crude glycerin (CG) along with animal waste has been an excellent option for increasing the production of biogas and methane to achieve efficiency in the treatment of both residues. This study aimed to evaluate improvements in specific productions of biogas and methane, reductions in solid and fibrous components in substrates

5. 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

6. Microbiology of organic and conventionally grown fresh produce
ABSTRACT Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues o

7. Stabilization of confined beef cattle manure: characteristics of produced fertilizers
ABSTRACT The growing demand for animal protein is directly related to the feedlot system of animals and their assumptions, such as the waste management. The characterization of the final products becomes an important factor in decision making by one or by other process. The objective was highlight characteristics that fertilizers present due to the used of s

8. Halotolerant bacteria in the São Paulo Zoo composting process and their hydrolases and bioproducts
Halophilic microorganisms are able to grow in the presence of salt and are also excellent source of enzymes and biotechnological products, such as exopolysaccharides (EPSs) and polyhydroxyalkanoates (PHAs). Salt-tolerant bacteria were screened in the Organic Composting Production Unit (OCPU) of São Paulo Zoological Park Foundation, which processes 4 ton/day

9. Avaliação ecotoxicológica do uso de dejetos de suínos em solos de Santa Catarina / Ecotoxicological evaluation of swine manure usage in soils from Santa Catarina State Brazil
O Brasil ocupa a quarta posição entre os maiores produtores mundiais de carne suína. Destaque nacional deve ser dado ao estado de Santa Catarina, que detém 25% da produção do Brasil. Em Santa Catarina, a intensificação da produção em pequena área territorial gera um grande aporte anual de dejetos de suínos por unidade de área agrícola. Isso se

10. AvaliaÃÃo do potencial de aproveitamento tÃrmico do metano a partir de dejetos suÃnos na microbacia hidrogrÃfica do Rio Marreco, oeste do Paranà / Evaluation of the potential thermal utilization of methane from swine manure in Rio Marreco watershed, west of ParanÃ
A produÃÃo de proteÃna animal à uma atividade que vem se destacando na regiÃo Oeste do estado do ParanÃ. O desafio à gerir este sistema do ponto de vista ambiental, pois esta atividade produz quantidades significativas de dejetos com alta carga poluente. Em contrapartida, apresenta grande potencial de geraÃÃo de energia, pois, se tratada adequadamen

11. Tratamento e reuso do efluente de biodigestores no processo de biodigestão anaeróbia da cama de frango / Treatment and reuse of efluent of digesters in the anaerobic digestion of poultry litter
The anaerobic digestion process contributes as a method of treating poultry litter and energy generation. However, its applicability may cause some counter-intuitive, requiring for dilution to provide a suitable environment for microorganisms active in the anaerobic process. This dilution increases volume and difficulty of disposal of effluent. Thus, the obj

12. Seed quality and optimal spatial arrangement of fodder radish
Besides the use of fodder radish (Raphanus sativus var. oleiferus Metzg.) as green manure plant cover crops and animal feed, the seeds have high oil content and low viscosity, ideal characteristics for the production of biodiesel. Studies related to the technology of seed production for this species are insufficient to define the best spatial arrangement of
