Maria Eunice Paulade Souza, André Mundstock Xavierde Carvalho, Daniely de Cássia Deliberali, Ivo Jucksch, George Gardner Brown, Eduardo Sá Mendonçaca, Irene Maria Cardoso Abstract The growth of earthworms in substrates enriched with rock (gneiss and steatite) powder, and the potential of vermicomposting in increasing solubilization of minerals present in rock powder and in promoting plant growth were evaluated.
