Resumo: | The aim of this work was to compare aggregate disruption of undisturbed soil samples by ultrasonic energy to aggregate disruption caused by the energy of simulated raindrops, to provide equations that can describe this relationship, and to evaluate whether aggregate stability, expressed by sonication method, may be used to estimate the effect that raindrops have on undisturbed soil samples. Undisturbed soil samples from A, Bi and C horizons of a Cambisol were submitted to different levels of ultrasonic energy and simulated raindrops. Sieved samples (aggregates) were also submitted to different levels of ultrasonic energy so that both disturbed and undisturbed conditions of samples could be compared. The results showed that the method using ultrasonic energy on undisturbed soil samples can simulate the amount of aggregate disruption of soil due to raindrop impact. Dispersion curves of disturbed samples may not be used to estimate the effect of raindrops on undisturbed soil samples. |

Amostras indeformadas dos horizontes A, Bi e C de um Cambissolo Háplico foram submetidas a diferentes níveis de energia ultra-sônica e gotas de chuva simulada. Amostras peneiradas (agregados) também foram submetidas a diferentes níveis de energia ultra-sônica para obtenção de curvas de desagregação. Os resultados mostraram que a quantidade de solo desagregado pelo impacto das gotas de chuva pode ser simulada pela aplicação de energia ultra-sônica sobre amostras indeformadas de solo. Curvas de desagregação de amostras deformadas não podem ser usadas para estimar o efeito das gotas de chuva sobre amostras indeformadas de solo.Universidade Federal de Lavras2019-10-15T18:55:01Z2019-10-15T18:55:01Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRIBEIRO, B.

Undisturbed soil samples from A, Bi and C horizons of a Cambisol were submitted to different levels of ultrasonic energy and simulated raindrops. Sieved samples (aggregates) were also submitted to different levels of ultrasonic energy so that both disturbed and undisturbed conditions of samples could be compared. The results showed that the method using ultrasonic energy on undisturbed soil samples can simulate the amount of aggregate disruption of soil due to raindrop impact. Dispersion curves of disturbed samples may not be used to estimate the effect of raindrops on undisturbed soil samples. |
