Macrofauna edáfica como bioindicadora de qualidade de solo com diferentes tipos de uso, Campo Mourão, Paraná.

Abstract

The edaphic macrofauna is composed of organisms that live all or part of their lives in the soil performing important functions, such as litter and soil modification. In addition, they are important for soil quality assessment. This work aimed to characterize the soil macrofauna of three soils with different exposure in order to verify the quality of the three areas located in the Rural Association of Parents and Friends of the Exceptional (APAE) of Campo Mourão-PR. The study period covered August, October and December, 2017, and February and April, 2018. Data on the environmental variables of soil temperature and soil moisture were collected weekly at the three points within each area. always in the mornings. The soil for obtaining macroinvertebrates was collected bimonthly. The laboratory analysis of soil macro and micro nutrients was carried out in October 2017 and April 2018, in the three study areas, in order to obtain the pH, Al, Ca, Mg, K, P, CTC and COT. Hymenoptera was the most prominent group in the three study areas being represented entirely by the family Formicidae, followed by Isoptera and Annelida. Almost all taxonomic groups in the three study areas had the largest abundance of individuals in the first soil extract (0-10 cm), with decrease as the depth of the samples increased. The highest diversity was presented by the Forest (H '= 0.68), which also presented greater abundance homogeneity (E = 0.61) (Table 2), ie better distribution of invertebrates in the taxonomic groups collected, a fact that may represent higher quality soil.
