INFLUENCE OF Phosphorus AND Sulphur ON ASSOCIATED MICROBIOTA IN ROOT AND RHIZOSPHERE OF SORGHUM
R Carrenho & EL Balota
ABSTRACT: In this study we verify the influence of homeophatic solutions of Phosphorus and Sulphur in three dynamizations (6CH, 30CH, 100CH) on growth of sorghum and microorganisms associated to its roots and rhizospheric soil after 3 months of cultivation under pot conditions. Dry matter of shoot were not influenced by solutions, but proportion and content of phosphorus in plant tissues were increased by P6CH and P30CH. Phosphorus solutions reduced number of mycorrhizal propagules in soil, root colonization and microbial biomass. Almost of all investigated soil properties were not altered by the homeopathies, except potential and active acidity and carbon level, which were increased by Sulphur solutions. Also, P30CH and P100CH influenced potential acidity and carbon level, increasing them. Data from this study showed the nature of the two polychrests interfere differently on biological and chemical variables.
Keywords: microbial biomass, colonization, arbuscular mycorrhiza.
