Nutrient storage in roots and rhizomes of hexaploid Caucasian clover
Abstract
Hexaploid Trifolium ambiguum M. Bieb.
(Caucasian clover cv. Prairie) persisted and
dominated in high country plots which received
more than 100 kg P/ha at establishment. After 13
years the biomass of coarse roots (rhizomes and
tap-roots) amounted to 20 t/ha. The contents of
nutrients in the root fractions were approximately
five times that in the herbage. This ability to
retain nutrients in coarse roots may be a strategy
that contributes to the dominance of Caucasian
clover on this acid soil.
