Description and Uses
Acacia sieberiana (Umbrella thorn) is a
tropical
tree from
Southern Africa . It is mainly grown for its
conservation crops
, which have a
medium shelf life. The crop is harvested by
total removing. 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;
timber, fuel, ornamental, fodder, gum resin, poison herbicide, The
{missing data} is used as
{missing data} . The
{missing data} is used as "

phytochemical. There is
{missing data} extracted by
{missing data} from the
tree's
{missing data} yielding
{missing data} -
{missing data} oil. The
tree's wood is called
{missing data} and has a density of
0 -
0 kg/m³. Regarding firewood production the
tree's growing speed is
medium, it's energetic value is
0 ckal/kg and the wood's drying speed is
{missing data}. After
40 years the
tree can be totally removed as it reached its commercial and ecological goal.
Acacia sieberiana has a lifespan of
100 years.
Environmental limitations
The tree is
23 meters tall with a crown of
10 meters wide. The
tree prefers a planting distance of
500 cm and a row distance of
500 cm. It is
fast growing and
intolerant to shade.
Acacia sieberiana has a
deep root-system and it has symbiotic associations with the
fungi
(endo-mycorrhiza). It is
able to fix nitrogen moderately with
"Microbacteriaceae bacteria. The name(s) or string of bacteria include(s)
