Resumo: Effect of adding organic residues to soil in ammonia losses by volatilization due to urea application is evaluated, together with autoclaving at 120°C, at 1 atm, during two hours. Samples of Ap surface of structured eutrophic dark red latisol (Rhodic Kanhapludalf, clay texture) from the municipality of Piracicaba SP Brazil, were used. Autoclaving delayed the peak of losses and increased loss of ammonia up to 56%. Autoclaving did not delete the stimulating effect of organic residues on the volatilization of ammonia (NH3). Autoclaving partially decreased the effect on peat and enhanced ammonia loss in cattle manure and house garbage. Autoclaving increased pH of soil and of cattle manure; slight changes in pH also occurred in other residues

Foram utilizadas amostras do horizonte Ap de uma Terra Roxa estruturada eutrófica (Rhodic Kanhapludalf, classe textural argila) do município de Piracicaba, Estado de São Paulo. A autoclavagem retardou o pico de perdas e aumentou as perdas de amônia em até 56%. A autoclavagem não eliminou o efeito estimulante dos resíduos orgânicos sobre a volatilização de amônia (NH3); para a turfa, a autoclavagem apenas reduziu parcialmente esse efeito, enquanto que para o esterco de curral e para o composto de lixo, a autoclavagem estimulou ainda mais as perdas de amônia. A autoclavagem elevou o pH da terra e do esterco de curral, ocasionando alterações pequenas no pH dos demais resíduosUniversidade Estadual de Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/256510.4025/actasciagron.v23i0.2565Acta Scientiarum.
