Description and Uses
Ulmus laevis (European White Alm) is a
temperate
tree from
South East Europe . 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, . The
{missing data} is used as
inedible . The
{missing data} is used as "
{missing data} " with
{missing data} ({missing data} -

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
640 -
640 kg/m³. Regarding firewood production the
tree's growing speed is
fast, it's energetic value is
4400 ckal/kg and the wood's drying speed is
{missing data}. After
30 years the
tree can be totally removed as it reached its commercial and ecological goal.
Ulmus laevis has a lifespan of
120 years.
Environmental limitations
