takes 2 years to make an apple fruit tree and 3 years to make
a pear fruit tree. Every time that we plant bench grafts or
sleeping eyes we use fresh soil. It is not possible to use one
parcel more than once because of a kind of soil sickness.
Crop protection is very important. It takes
2 days each week to control the whole nursery. After the inspection
we make a report of what we have seen and we make a list what
has to be sprayed. To spray the trees we use a spraying machine
with air support and a spraying computer. On both sides of the
machine the spraying boom is 14 metres; total 28 metres. The tank
contains 2800 litres. Mostly we use 200 litres per ha. That means
that we can spray 14 ha with one tank.
The trees are lifted with a machine that can dig
out about 30.000 trees per day. The trees are graded in the
field in different qualities and collected on iron pallets.
The lifted trees are transported to a storage shed. Here they
are regularly moistened by a sprinkle installation that produces
a kind of fog.
If possible we deliver the trees within a
week after lifting. If it is necessary to store the trees for
a longer time (2-3 months) we put the trees in a cool store at
1°C. For the transport of the trees we use a closed truck
so that the trees cannot desiccate.
All the rootstocks, bud and graft wood we use
are certified by the NAK-tuinbouw (Inspection Service for Floriculture
and Arboriculture) and, as far as available are virus free.
Some new varietis are not yet 100% virus free. In spite of that
it is possible to buy bud and graft wood of such a variety.
To make it clear to the costumer that these trees are not complete
virus free the trees get a white label. Trees that are virus
free gat an orange label.
An independent inspector of the Inspection
Service regularly inspects the plants in the nursery.
