13. Avaliação agronômica e econômica da aplicação de biossólido na produção de soja.
O objetivo deste trabalho foi definir parâmetros técnicos e econômicos do uso de biossólido como fertilizante para a soja. A resposta da soja à aplicação de biossólido úmido, nas doses 0, 7,5, 15, 30 e 45 Mg ha-1 foi comparada à resposta ao fertilizante mineral, aplicado em quantidades equivalentes de NPK, por dois anos de cultivo, em um Latossolo

14. Sewage sludge application in cane-plant as nitrogen and phosphorus source and its environmental effects / Aplicação de lodo de esgoto em cana-planta como fonte de nitrogênio e fósforo e seu impacto ambiental
The potential agricultural use of the sewage sludge is due to their organic matter and nutrients contents, mainly nitrogen and phosphorus, the most important constituint. However, there is a lack of research to adequate the nitrogen and phosphate fertilizer doses to be applied in agricultural fields treated with this residue. Despite the evident benefits of

15. Influência do lodo de esgoto na nodulação e no desenvolvimento do Caupi (Vigna unguiculata "L" Walp)
The intense urban growth, production of domestic and industrial residues has been increased, mainly sewage sludge. This residue has high amount of pathogenic organisms and heavy metals. The viable alternative for this residue destination is its use in agriculture improving the chemical, physical and biological soil characteristics. Allied of the capacity of

16. Uso do lodo de esgoto (biossólido) como fertilizante em eucaliptos: demanda potencial, produção e crescimento das árvores e viabilidade econômica / Use of sewage sludge (biosolids) as a fertilizer in eucalypts forest plantations: potential demand, production and growth of the trees and economic viability
This work evaluates the use of the residual sludge (biosolids) produced by sewage treatment units located in the Metropolitan Region of the City of São Paulo (MRSP) as a fertilizer in Eucalyptus grandis forest plantations. The aspects studied were potential demand, wood production response to the fertilization, trees growth and economic viability. A high le

17. Uso de lodo de esgoto na cana-de-açúcar como fonte de nitrogênio e fósforo: parâmetros de fertilidade do solo, nutrição da planta e rendimentos da cultura / Use of sewage sludge on soil planted with sugarcane as nitrogen and phosphorus source: soil fertility attributes, plant nutrition and yield
The use of sewage sludge on land can improve soil fertility considering nitrogen, phosphorus and organic matter inputs. The aim of these experiments was to evaluate the effect of sewage sludge on soil, sugarcane plants and sugarcane yield in substitution to nitrogen and phosphorus from mineral fertilizers. The effect of the sewage sludge as a source of nitro

18. Influência da aplicação do lodo de esgoto (Biossólido) sobre a concentração e o estoque de nutrientes na biomassa do sub-bosque, na serapilheira e no solo de um talhão de E. grandis. / Influence of sewage sludge application (biosolids) on the concentration and stock of nutrients in the understory biomass, litter and soil in a stand of Eucalyptus grandis.
The increasing of urban population generates the need for an ecological and social acceptable disposal of sewage sludge produced by waste treatment plants. Therefore, the use of the sewage sludge (biosolid) as fertilizer and soil conditioner in forests plantations may be a suitable solution, becoming possible the increment of renewable wood production. Howev

19. Potencial do lodo de esgoto calado como insumo agrÃcola para a cultura do milho em latossolo vermelho
The sewage sludge is a by-product resulting of the sewage treatment that contains high organic matter concentration and that, properly applied, it can to supply improvements in the soil fertility. The objective of this study was to evaluate the sewage sludge agricultural potential. The experiment was accomplished in field, in the year of 2004, with randomize

20. Ciclagem de nutrientes após aplicação de lodo de esgoto (Biossólido) sobre latossolo cultivado com Eucalyptus grandis / Nutrients cycling after sewage sludge (biosolid) apllication on oxisol planted with Eucalyptus Grandis
The treatment of wastewaters generates the sewage sludge, a residue that could be used to increase the productivity of both farming and forest plantations. The general aim of this work was to evaluate how biosolid affects the biogeochemistry of nutrients at an Eucalyptus grandis plantation. The study site is at the Experimental Station of Itatinga, linked to

21. Investigation of Salmonella infection in goats fed corn silage grown on land fertilized with sewage sludge.
A total of 36 goats were fed for 17 months with corn silage grown on land fertilized with human sewage sludge. These animals were investigated for salmonella infections. Salmonellae were not detected in cultures of fecal or silage samples. No significant agglutination titers were detected in goat sera examined. Salmonella newport C2 was isolated from the slu

22. Survival of coliform bacteria in sewage sludge applied to a forest clearcut and potential movement into groundwater.
Anaerobically digested dewatered sludge (10 to 15 cm thick) was applied to a forest clearcut as a fertilizer source in northwest Washington on gravelly glacial outwash soil. This sludge is not microbiologically sterile and may contain pathogenic organisms. Fecal coliform bacterial counts in sludge applied in summer (July) fell from 1.08 X 10(5) to 358/g in 2
