EMBRAPA FLORESTAS | Soil macrofauna communities in various land use systems in Canoinhas and Três Barras, Santa Catarina state, Brazil

Citation

Description

Soil macrofauna communities were evaluated in May 2011 in five land use systems in the region of Canoinhas and Três Barras, Santa Catarina state, Brazil. In Três Barras, samples were taken in a native Atlantic Forest fragment and an Araucaria angustifolia tree plantation in the Três Barras National Forest, as well as in an annual grain crop production system under no-tillage on a private farm. In Canoinhas, samples were taken in an agropastoral system with Italian ryegrass (Lolium multiflorum), and in a permanent pasture of native grasses. Nine samples were taken in each land use system in a 3x3 square grid with 30 m distance between samples. Samples were taken using the standard methodology of the Tropical Soil Biology and Fertility Programme (TSBF), where soil (down to 20 cm depth) and litter fauna were hand-sorted from monoliths of 25x25 cm, and the abundance of a total of 42 taxa was assessed.
