Resumo: Improving the efficiency of the earthworms separation process from its substrate (humus) is important because this is the most labor and time intensive stage. In this study the same techniques used in electrical fishing was employed with some adaptations for earthworm separation. Therefore, the effect of an electric field produced by controlled electric signals was studied for displacement of the earthworm Eisenia fœtida. The study was conducted at the Energy in Agriculture Laboratory of the Department of Agricultural Engineering, Federal University of Viçosa, MG. The earthworms preferentially moved towards one of the electrodes, as observed in more than 90% of the cases. Therefore, based on these results, it could be concluded that utilization of controlled electrical signals is technically suitable for separation of earthworms from humus.

Neste trabalho, as mesmas técnicas usadas na pesca elétrica foram utilizadas com adaptações para a separação de minhocas. Assim, avaliou-se o efeito de um campo elétrico, produzido por sinais elétricos controlados, no deslocamento de minhocas Eisenia fœtida. O estudo foi realizado no Laboratório de Energia na Agricultura do Departamento de Engenharia Agrícola da Universidade Federal de Viçosa, Viçosa, MG. As minhocas se deslocaram preferencialmente para o anodo, em mais de 90 % das observações. A partir dos resultados obtidos, pode-se afirmar que a utilização de pulsos elétricos controlados é viável tecnicamente para separação de minhocas do húmus.Engenharia na Agricultura2017-12-19T16:22:01Z2017-12-19T16:22:01Z2013-07-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf2236-5176http://www.seer.ufv.br/seer/index.php/reveng/article/view/411/287http://www.locus.ufv.br/handle/123456789/15675engv. 21, n. 6, p. 527-538, Nov./Dec. 2013Moraes, Maria Joselma deOliveira filho, DellyMartins, José HelvécioSantos, Luiz Carlos dosinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T08:33:18Zoai:locus.ufv.br:123456789/15675Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T08:33:18LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
