E.  aComparative growth responses of perennial forage legumes in hill-land ultisols and their relationship to soil acidity-related factors.  c1989  aAs soils of humid, temperate hill-lands are typically highly weathered, mineral, and acidic, forage legumes for these conditions need to be evaluated, and limiting soil acidity-related factors determined. Two ultisol topsoils (0-15cm) from  Appalachina hill-lands of the lily series (Typic hapludults) were utilized in a growth chamber experiment. Both soil were of similar pH and low in fertility but different in % base saturation due to different management histories (abandoned versus poorly-managed pasture). Treatments to provide a range of soil pH values (Aluminium, nil, calcium) were applied to ascertain their effect on various growth response traits of alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.), white clover (Trifolium repens L.),birdsfoot trefoil (Lotus corniculatus L.), big flower vetch (Vicia grandiflora Scop.), and flatpea (Lathyrus sylvestris L.). Averaging over all soils and treatments, shoot production increased in the order-alfalfa &lt red clover, white clover...  aacidity  aalfalfa  alegumes  aUltisols  aAcidez  aAlfafa  aPastagem  aTrevo  aClover  aLeguminosas  aPasture  aUltissolos1 aWRIGHT, R.
