The objective of this work was to evaluate the abundance of the soil macrofauna in four green manure species, before the cotton crop.
The experimental design was a randomized block design with four treatments:
Mucuna pruriens (gray mucuna), Canavalia ensiformes (pork bean), Cajanus cajan (pigeon pea) and Crotalaria juncea (crotalaria). The macrofauna was captured by means of collections with collections using pitfall traps. The data were processed through the cluster analysis to verify the similarity among green manure species as to the occurrence of soil macrofauna. The orders Orthoptera, Coleoptera L (Larval), Hymenoptera and Coleoptera (adult), respectively, had the highest local relative abundance. There was a significant effect of the cover plants on the taxonomic groups and relative density of the soil macrofauna. Green manures were more determinant in the abundance and relative density of the soil macrofauna than the region climate. Up to 60 days after sowing the cotton crop, there was a beneficial influence of the green manures on the soil macrofauna.
Objetivou-se avaliar a abundância da macrofauna do solo em quatro espécies de adubos verdes, antecedendo a cultura do algodão. O experimento foi instalado na Universidade Estadual de Mato Grosso do Sul - Unidade Experimental de Aquidauana, MS.
