Eucalyptus is versatile, fast
growing and strongly coppicing tree possessing a wide range of soil and
climatic adaptability. E.tereticornis has the most extensive latitude range
(9-380S) of any species in the genus. Basically a light demander,
the growth of the species is very much reduced under shade. Eucalyptus is known
for its drought hardiness, although annual rainfall of 800 mm is preferred. The
species is also moderately salt tolerant and relatively fire resistant.
Eucalyptus is generally regarded as frost sensitive, though in Uruguay, E.
tereticornis has known to come up with reasonable success in regions where
unseasonal frost is likely to occur. The species is known to suffer cholrosis
and die-back due to the reduced iron absorption in alkaline soils.
The species grows under a wide range of
climatic/soil conditions from warm to hot, sub humid to humid and from good to
degraded soils. The range of agro-climatic conditions of the species ( E.
tereticornis) is given as under:
