Arthropofauna of soil associated with cultivation Dominico Hartón (Musa AAB) in Calarcá, Quindío

Abstract

In this paper we analyze the edaphic arthropod community structure associated to a secondary forest in Calarcá-Quindío, and a plantain crop under organic amendments (Necromasa, Compost) and under agrochemicals, with two planting distances between plant and plant (1.7m and 2.5m), between June 2013 and January 2014, under the methodology proposed by the Programme Tropical Soil Biology and Fertility; during the analysed period were taken three (3) soil monoliths every month. Were collected 18929 individuals distributed in 52 families of insects, 16 of millipedes, 8 of arachnids and 1 crustaceans. Sampling effort is represented by ACE and Chao 1 estimators higher than 82% for both coverages (crop and forest). In general, there were no differences in the community structure due to the treatments. Nevertheless the arachnid and myriapod communities were substantially affected, while insects were altered by the crop microclimate variation. It is concluded that the type of fertilization and planting distances do not affect the soil arthropods, but modifies the soil microclimatic and biological conditions.
