Fauna edáfica influenciada pelo uso de culturas e consórcios de cobertura do solo

Abstract: A fauna edáfica é sensível e responde, com relativa rapidez, ao impacto de diferentes tipos de sistemas de produção, possibilitando, deste modo, o seu uso como componente ativo na avaliação da qualidade do solo. O presente trabalho objetivou determinar a influência do cultivo de aveia preta, nabo e ervilhaca e dos consórcios nabo/aveia preta e ervilhaca/nabo/aveia preta, na estrutura e composição da fauna edáfica. O delineamento foi em blocos casualizados, em esquema fatorial 6x4, sendo seis culturas de cobert… Show more

“…In this regard, the Shannon's diversity index showed a tendency of association in the BOFT system, dominance and abundance of individuals showed a tendency of association with WL, and Margalef's richness did not associate with the studied systems (Figure 1). Similar results were described by Silva et al (2013a), where there was a tendency of association of fauna diversity with combined cover crops. Therefore, the use of combined cover crops seem to favor the edaphic fauna diversity.…”

“…According to Chauvat et al (2003) this variable is influenced by the quality of the plant residues. In this regard, it has been observed that leguminous plants allow for a larger relative density of invertebrates in the soil (SANTOS et al, 2008), as a result of the lower C/N ratio (SILVA et al, 2009), and the use of consortia of different cover crops increases the total individuals density (SILVA et al, 2013a). Such evidences can explain the larger amount of individuals in FL, because of the higher diversity of plant species in this system, which act as a consortium of wild plants, and in WL and VT for being leguminous plants.…”

“…Uma dessas estratégias se refere ao uso de rotações de culturas e plantas de cobertura, que contribuem diretamente nas relações entre a biota encontrada sobre e sob a camada superficial do solo, principalmente a fauna edáfica, conforme estudos realizados por Silva et al (2013) e Gatiboni et al (2011). O primeiro estudo verificou que plantas de cobertura pertencentes a família das leguminosas favorecem uma maior densidade relativa de invertebrados do solo, enquanto que as gramíneas favorecem os grupos da serrapilheira.…”
