Description and Uses
Acacia mearnsii (Black wattle) is a
tropical
tree from
Southern Australia . It is mainly grown for its
tannin crops
, which have a
very long shelf life. The crop is harvested by
pruning. It starts flowering after
0 -
0 years. The yield will be
{missing data}, but in its top season there will be a yield of
{missing data}. Other crop types include;
ornamental, timber, fuel, fodder, apiculture, fertilization, The
{missing data} is used as

{missing data} oil. The
tree's wood is called
{missing data} and has a density of
700 -
850 kg/m³. Regarding firewood production the
tree's growing speed is
slow, it's energetic value is
4000 ckal/kg and the wood's drying speed is
{missing data}. After
45 years the
tree can be totally removed as it reached its commercial and ecological goal.
Acacia mearnsii has a lifespan of
80 years.
Environmental limitations
The tree is
23 meters tall with a crown of
12 meters wide. The
tree prefers a planting distance of
400 cm and a row distance of
400 cm. It is
slow growing and
intolerant to shade.
Acacia mearnsii has a
deep root-system and it has symbiotic associations with the
fungi
(endo-mycorrhiza). It is
able to fix nitrogen moderately with
