Abstract Perennial pasture species are important for sustainable pasture systems; yet some species display poor persistence on acid soils. This work investigated the effect of soil acidity on primary root length and root-hair and rhizosheath development of five perennial grass genotypes varying in acid-soil resistance. Plants were grown in three low-P acid soils that were limed (CaCO3) to modify soil pH (0.01 M CaCl2 extractable) from 5.0 and Al3+ concentrations from ≥ 16 to
