An experiment was carried out under greenhouse conditions to evaluate the effects of arbuscular mycorrhizal fungi (AMF) and, or rhizobium inoculation, with the addition of industrial waste from lactic acid production (Ferkal), on the growth of Mimosa caesalpiniaefolia. Plastic pots of 6 L of capacity were used, filled with degraded soil from clay extraction areas with four levels of the Ferkal residue (0, 50, 100 and 200 g dm-3). Six microbiological treatments were conducted: indigenous AMF; AMF Glomus clarum; rhizobium; indigenous AMF + Rhizobium; […]
