Análise comparativa de vermicompostos com diferentes substratos de animais não ruminantes com minhocas africanas

Abstract

The vermicompost began to expand around the world in the 70's, and it was studied by the scientific community. The objective of this work was to evaluate the reproduction and development of African giant earthworms on different substrates with manure of non-ruminant animals, common grass (Urochloa mosambicensis) and ear of jaguar. To evaluate the different substrates of non -ruminant animals with African giant worms (Eudrilus eugeniae). The work was carried out at the Federal Rural University of Pernambuco (UFRPE) -Academic Unit of Serra Talhada (UAST) -PE, being divided into two stages, in the first the substrates were produced and in the second the vermicompost was produced. After the end of the 35-day vermicompost, the counting of the worms, washing and weighing were carried out, where they had the in-natura weight of each repetition of the treatments, after being added in identified bags and taken to the final drying oven, at the end removed the bag and weighed again getting the dry weight. The variance analysis was performed for thefollowing variables: N, Ca, Mg, P, K, Zn, Cu, B, Fe, Mn, CTC, pH, and weight of adult worms. African giant earthworms showed better development on the substrate with rabbit manure.The vermicompost presented the best chemical composition and higher levels of macro and micronutrients with rabbit manure substrate.
