Accessions from 9 Lotus species were tested for tolerance to salinity and-or acidity. Salt tolerance was tested in sand culture with NaCl the dominant salt. The growth of accessions within the species L. maroccanus, L. tenuis, L. angustissimus, L. corniculatus, and L.subbiflorus was not significantly affected by salinity at test levels. Tolerance to acidity was assessed in nutrient solutions with aluminium and manganese at pH 4.5. L. pedunculatus cv. Grasslands Maku and an accession of the winter annual L. purshianus were tolerant to both aluminium and manganese; the L. corniculatus accessions were intermediate in their tolerance to acidity.
