Avaliação da comunidade de invertebrados de solo em diferentes sistemas agrícolas

Abstract

It was made the evaluation of the community of soil invertebrates in different agricultural systems. Invertebrates were collected in areas with covers of Mucuna (Mucuna), Crotalaria (Crotalaria juncea), Millet (Pennisetum glaucum), Guandu (Cajanus cajan), Spontaneous vegetation and Mowing area. The sampling was performed through the pitfall traps placed by random draw in areas with about 10m² in size. The evaluation occurred in the countryside of Chapecó, in the experimental field of Agronomy at the Federal University of Fronteira Sul. The objective of the evaluation was to identify the abundance, diversity and dominance of soil invertebrates. The results showed significant differences between areas in relation to abundance, diversity and dominance.The mowing area had greater diversity. In abundance of soil invertebrates, the areas with Guandu, Milheto and Crotalaria had larger amounts. In relation to the dominance, the areas with Crotalaria, Milheto and Guandu had higher indices, with predominance of the order Collembola and the family Formicidae.
