The set of animals visible to the naked eye in an ecosystem is called a macrofauna, and it plays an important role in the soil food chain, stimulating the microbial activities responsible for soil mineralization and humidification, and supplying nutrients available to plants (KORBOULEWSKY et al., 2016). Considering that the analysis of the soil macrofauna is efficient to indicate environmental quality, researchers from the Universidade Estadual Paulista<\/em> (UNESP) in partnership with the Universidade de Rio Verde<\/em> (UniRV), Universidade Estadual de Campinas<\/em> (UNICAMP) and the Technological Innovation Center from Supera Parque de Tecnologia<\/em> evaluated the soil macrofauna of an area under recovery with planting different types of vegetation cover. The article \u201cSoil macrofauna as a bio indicator of the recovery of a degraded Cerrado soil<\/a>\u201d was published in the journal Ci\u00eancia Rural<\/em> (vol. 50, no. 8).<\/p>\n

The experimental area used is located on the Paran\u00e1 River Sedimentary Basin Plateau, on the right bank of the Paran\u00e1 River, in Selv\u00edria, Mato Grosso do Sul, Brazil. The environmental impacts present in the area are due to the construction of the Ilha Solteira<\/em> hydroelectric plant, in the interior of S\u00e3o Paulo, which started in the 1960s. In 2005, a plan to recover the degraded area in the municipality of Selv\u00edria \/ MS was started with planting of species plants adapted to the Cerrado biome, to repair an average removal of 8.60 m of soil in depth.<\/p>\n

The soil macrofauna was analyzed in 2005, 2006 and 2007, according to the method of direct collection and manual counting. During the research, numbers related to the number of species and diversity and uniformity indexes were determined. The results showed that the use of two plant species, one forest (Astronium fraxinifolium)<\/em> and another grass (Brachiaria decumbens<\/em>), associated with the use of sewage sludge increased the population and diversity of the soil macrofauna and comparatively exceeded the amount of soil species in area one with native Cerrado vegetation, indicating that it is an alternative for the recovery of degraded soils in the Brazilian Cerrado.<\/p>\n

According to researcher Rose Luiza Tavares, the research shows an alternative for the recovery of degraded areas in the Cerrado, making use of species adapted to the ecosystem itself and thus, reducing costs with the soil recovery process. \u201cOur work encourages the practice of revegetation of degraded areas, aiming to minimize soil erosion and land devaluation,\u201d adds the researcher. The use of this technique also makes it possible to reuse the biosolid from water treatment, which is currently considered problematic in terms of its final disposal.<\/p>\n
