The
comparatively small grain of the onion has high demands on the preparation
of the soil. The flat sowing depth, which includes the risk that
the surface dries out, make it necessary that capillary water from
the soil is regularly supplied, which means that the underground
must be very compact and solid. At the same time, the grain disposes
of few reserve substances, which could increase the vigour and thus
the field germination of the plants.
A good
crumble structure, resulting from the preparation of the soil and
a well-balanced supply of nutrients, makes it easier for the delicate
seedling to push through the surface. Particular on heavier soils
it is recommendable to prepare the beds already in autumn so that
in spring one single treatment of the crumble structure is sufficient.
Rule:
The underground as solid as possible, the surface as fine-grained
as possible
