S ummary The effects of inoculation with vesicular–arbuscular mycorrhizal (VAM) fungi on alfalfa ( Medicago sativa L.) growth and phosphorus uptake were studied in a moderately acidic loess soil with four levels of added lime. Inoculation of alfalfa with VAM fungi from soils of pH 7.2 to 7.5 resulted in increased dry matter production at pH of 6.4 to 7.5, but not at pH of 5.4 to 6.1. Addition of lime and/or phosphorus always increased growth of alfalfa. Root colonization by indigenous mycorrhizal fungi was inhibited at the highest pH levels but root colonization by added fungi was stimulated at higher pH levels and inhibited at the lower pH levels.
