Most commercial Brachiaria species are adapted to low-fertility acid soils of the tropics. We
describe, with examples, some of the attributes that enable them to adapt. These include the
ability to (1) maintain root growth at the expense of shoot growth;(2) acquire and use both
nitrate and ammonium forms of N;(3) acquire N through associative fixation;(4) acquire p
through extensive root systems and association with vesicular-arbuscular mycorrhizae; and
(5) acquire Ca through extensively branched roots with large numbers of root tips. Although …
