ABSTRACT The aim of this study was to evaluate the influence of fruit-crop management (mango, guava and coconut) on the composition and distribution of soil arthropods (mesofauna and macrofauna) during seasonal periods in the Curu Valley region of the State of Ceará, Brazil. The study was carried out during the following periods: rainy/dry (July/August 2013), dry (October/ November 2013), dry/rainy (January/February 2014) and rainy (April/May 2014). Pitfall traps were used to capture the arthropods. After sorting, the Shannon-Wiener diversity index and the Pielou evenness index were calculated. Diversity values were compared in pairs using Student's t-test (α = 0.05) in the SAS v 9.0 software (2002). The similarity of the areas and groups was evaluated by... |

ABSTRACT: The use of wastewater in agriculture has been practiced on an increasing scale over the past decades because of its fertilizing potential and the reduction in demand for surface water and groundwater. However, this practice may bring harm when performed without planning, not respecting the capacity of the soil to recycle organic waste. The most common problems are contamination of surface and groundwater via leaching and runoff, as well as accumulation of nutrients and potentially polluting elements that compromise chemical, physical and biological characteristics of the soil. The biological compartment, represented by the micro, meso and macrofauna, plays an important role in nutrient cycling, decomposition of organic matter, particle movement... |
