A. odoratum populations from 8 plots of a long-term experiment given N, P, NP or no fertilizer, with or without lime, were grown in sand culture at 5 levels of P. Responses of populations to 0.5-8 mg P/l were closely correlated with the P content of their source soils, whereas responses to 0.5-128 mg P/l were more closely related with the pH of these soils; the differences had evolved over <65 years and over distances of <30 m. Populations collected from unlimed plots had higher concentrations of Ca and P in the shoot than did populations collected from limed plots.
