“…O grupo Collembola também se mostrou relacionado ao pH, o maior valor do parâmetro decorrente da calagem em B1 e B2 pode ter favorecido o grupo uma vez que, este responde as mudanças de pH advindas do manejo do solo (Silva et al, 2016). A calagem, com consequente elevação do pH, somada a existência de cobertura de solo (restos culturais) nos bananais pode ter beneficiado o grupo Acari, principalmente em B2 (maior pH) já que, no estudo de Giracca et al (2008), a elevação do pH através da calagem em áreas com cobertura de solo (plantio direto) teve efeito positivo sobre o grupo Acari.…”

AGRONOMIA (AGRONOMY)RESUMO: A fauna do solo é sensível as modificações no ambiente e, portanto, pode ser eficiente como indicadora de qualidade em áreas de produção de banana. O objetivo do estudo foi avaliar os efeitos da produção de banana sobre a fauna edáfica em função das diferentes práticas culturais, manejos e aspectos químicos e físicos do solo. Avaliaram-se dois bananais e uma área de mata nativa, no sul de Santa Catarina em duas épocas. Para coleta de fauna utilizou-se o método de armadilhas de queda e o monólito de solo e ainda, avaliou-se a química e física do solo. Para fauna avaliou-se a abundância e riqueza de organismos amostrados, índices de diversidade de Shannon-Wiener e Pielou e procederam-se análises multivariadas. Os grupos de destaque na coleta por armadilhas de queda nos bananais foram Collembola, Formicidae e Acari e na coleta pelo monólito de solo, os grupos Oligochaeta e Diptera (larvas). Quanto aos índices de diversidade os bananais apresentam maiores índices na última coleta pelo monólito de solo. Identificou-se relação da fauna com pH, Al +3 , Fe +3 , Zn +2 , Mg +2 , macroporosidade e densidade do solo. Conclui-se que as principais práticas culturais dos bananais relacionadas com a fauna são a calagem, adubação e disposição dos restos culturais no solo.

“…The surface liming influence on BD, TP and Ma might be related to biopore formation in the soil through (i) the slow and gradual decomposition of the fasciculate roots and stolons of the forage which covered the area prior to the experiment installation (Six et al ., ); (ii) crop root growth increases (Caires et al ., ); and (iii) higher density and activity of the soil macrofauna (Giracca et al ., ; Han et al ., ).…”

It is generally accepted that liming ameliorates soil acidity. However, the method of lime application is thought by many to influence its effectiveness in acid soils. In this study, we wanted to assess the degree of effectiveness of surface-applied lime and lime incorporated into the soil on soil structural attributes and water retention of a Dystrudept soil in the SE region of the State of Paran a, Brazil. Lime was added at the rate of 15 t/ha to soil through: (i) surface broadcasting, (ii) incorporation via ploughing and harrowing, (iii) incorporation via subsoiling and harrowing. A control treatment with zero lime application was included in the experiment. The addition of lime by surface broadcasting resulted in significant reductions in soil bulk density (BD) and macroporosity (Ma) and increases in total porosity (TP) and microporosity (Mi) of the top soil layer (0-0.10 m). The reverse was the case in the 0.10-to 0.20-m soil layer; where lime was incorporated via ploughing and harrowing, increases in BD and reductions in TP and Ma were observed. Addition of lime also significantly increased soil water retention, with maximum retention recorded from soil amended with surface broadcast lime. Changes in soil chemical attributes (increases in pH, Ca 2+ and Mg 2+ contents; reductions in potential acidity and Al 3+ content) were responsible for the changes observed in structural and physical attributes, and water retention. Bearing in mind the lower application costs, improvement in the soil chemical attributes for plant development and soil physical quality, surface broadcast lime can be considered a promising alternative for no-till farmers.

“…One way of evaluating whether the management practices used after mining are efficient is based on evaluating the presence, absence, density, diversity and functional role of soil organisms (Baretta et al, 2010), which are considered sensitive biological parameters to the effects of soil degradation (Giracca et al, 2008;Menta et al, 2011).…”

Soil Macrofauna as Indicator of Environmental Recovery in a Mining Area

et al. 2018

This work aimed to characterize the composition of the soil macrofauna in non-mined and mined areas recovered with native vegetation, Eucalyptus dunnii Maiden and Acacia mearnsii De Wild. plantations, in a coal mine. Five areas were evaluated, namely, three non-mined areas and two mined and recovered areas. Six soil samples per area were collected using a 10x10 cm circular probe, every month during one year. Defragmentation of the soil and removal of specimens was carried out in a laboratory. A total of 3,195 specimens from 11 taxa were collected. The most abundant groups were Hymenoptera, Isoptera and Coleoptera. There were significant correlations (p<0.05) between the total abundance of Isoptera and Coleoptera with some meteorological variables. The recovery process of the mined areas with black-wattle and eucalyptus plantations proved to be efficient because there was similarity of macrofauna groups between the non-mined, mined and native vegetation areas.
