Description and Uses
Quercus robur (Pedunculate oak) is a
temperate
tree from
North West Europe . It is mainly grown for its
timber crops
, which have a
medium shelf life. The crop is harvested by
ground gathering. It starts flowering after
20 -
25 years. The yield will be
1, but in its top season there will be a yield of
20. Other crop types include;
mulch, timber, fuel, ornamental, . The

beverage . The
bark is used as "

tannic acid (? -

phytochemical. There is

tree's

0 -
{missing data} oil. The
tree's wood is called
{missing data} and has a density of
650 -
750 kg/m³. Regarding firewood production the
tree's growing speed is
medium, it's energetic value is
4600 ckal/kg and the wood's drying speed is
medium. After
50 years the
tree can be totally removed as it reached its commercial and ecological goal.
Quercus robur has a lifespan of
1,500 years.
Environmental limitations
The tree is
30 meters tall with a crown of
22 meters wide. The
tree prefers a planting distance of
900 cm and a row distance of
900 cm. It is
fast growing and
intolerant to shade.
Quercus robur has a
deep root-system and it has symbiotic associations with the
fungi
(ecto-mycorrhiza). It is
not able to fix nitrogen with
"any bacteria. The name(s) or string of bacteria include(s)
"not applicable ". The
tree's flower-morphology is
monoecious and is pollinated by
wind.
Quercus robur is
deciduous in winter and
not allelopathic and has
no thorns.
Quercus robur thrives in an altitude of
0 to
1500 meters above sea-level
(temperate). The minimum temperature is
-20°C; optimally between
12 -
28°C. The optimal rainfall is
1550
mm/year. Without irrigation the annual rainfall should be between
550 -
2000mm (L/m²). The optimal soil-pH is between
5.0 -
6.0 in a soil texture of
sand. To salt it is
a bit tolerant to wind
tolerant and to fire
intolerant.
