ABSTRACT: The production of tree seedlings with high survival rate and growth is influenced by the substrate, which may be composed of biological and non-biological materials that help plant growth. The objective of this study was to evaluate the efficiency of a mycorrhizal inoculant on farm and the use of a potassic rock (phonolite) on growth and nutrition of Eucalyptus saligna Sm. and Schinus terebinthifolius Raddi under greenhouse conditions. Both species were assigned to three mycorrhizal treatments [no inoculated control […]

Production of arbuscular mycorrhizal fungi (AMF) inoculum using the on-farm method is an alternative to stimulate the use of microbial inoculant in plant production systems and to reduce the cost associated with purchase of this product. The goal of this study was to evaluate the potential of residues from the forestry industry, pine bark (CP) and pulp sludge (LC), as components of the substrate used to produce on-farm mycorrhizal inoculum. Sorghum plants pre-colonized with the AMFs Claroideoglomus etunicatum RJN101A and […]

A greenhouse experiment was carried out to evaluate the effect of sulphur (S) inoculated with Acidithiobacillus on phosphorus (P) availability from natural phosphate (NP) using different fertilizer application methods on yam bean (Pachyrhizus erosus) grown in a “Tableland Forest” soil (Podzol Hydromorphic dystrophic) of the “Zona da Mata” in the State of Pernambuco, Brazil. Plants were inoculated with rhizobia strains (NFN 747 and NFB 748) and control treatments added without rhizobia inoculation. The P treatments were: (1) NP pelleted with […]
