Alfalfa
-
Medicago
sativa L.
Alfalfa
has four root type systems: tap root, branch
root, rhizomatous root and creeping root. A
rhizomatous root system enables the plant to
spread from the crown by hor izontal stems and
develops very broad crowns. Creeping rooted
plants develop horizontal rootstalks from the
main roots. Shoots arising from the rootstalks
are capable of becoming independent plants.
Rhizomatous and creeping-rooted plants usually
are more persistent and tolerate adverse
climatic conditions better than tap and
branch-rooted plants. Alfalfa does best on deep
loam soils with high lime content. Alfalfa is
more adapted to the interior areas of B.C. than
coastal areas being that it is not tolerant of
soils with high water tables or soil pH below
6.0.
