E.  aEvaluation of the rhizosphere pH of two sorghum genotypes in presence of three aluminium saturations and three potassium levels in soil.h[electronic resource]  c2001  aThe rhizosphere pH of sorghum roots was evaluated by using microelectrodes in minirhizotrons containing six seedlings of two sorghum genotypes (SC-283, Al-Tolerant and Martin, Al-Sensitive). Measurements were made along the root surface and in the surrounding area of the roots, considered in this paper as the rhizosphere and rhizoplane values.  ametal tolerance  apotassium  arhizoplane  arhizosphere  aroots  aseedlings  asoil pH  aAluminium  aGenotypes1 aBALIGAR, V.
