COMPACT DISC HARROW
RUBIN 9
Stubble cultivation today
2
The modern stubble cultivator has three
main functions to encourage germina-
tion of weed and volunteer seeds; to in-
corporate straw; and to repair damage to
compacted soil.
Weed Control
If a crop is to achieve its maximum yield
potential, it needs to be able to grow free
from competition from weeds and volun-
teers. A good cultivator will encourage
weed and volunteer seeds to germinate
as soon as possible after harvest. They
can then be destroyed by chemical or
cultural means before the crop is planted.
To be efficient at weed control, the culti-
vator should prepare a seedbed similar to
that required by a grass ley - fine soil, with
seeds near to the surface, and firmed into
the ground to retain moisture. Once ger-
minated, the field can be cultivated again,
or sprayed with herbicide to kill the
weeds before the crop is planted.
Incorporate Straw
High yielding crops produce a lot of straw
which contains valuable nutrients that
will benefit crop growth if released into
the soil. Straw will decompose most rap-
idly if kept in the oxygen layer of the soil
(top 5cm) where aerobic bacteria are ac-
tive. Therefore, mixing straw, and other
crop residues, into the top 5cm immedi-
ately after harvest will encourage nutri-
ent release. Nearer to seeding time, non-
decomposed straw should be mixed
deeper into the soil, leaving clean soil
near the surface for seed germination
and root establishment.
Europes Leading Compact Disc Harrow
The Rubin is designed to intensively mix
soil and straw at depths of up to 10cm. It
is ideal for preparing a stale seedbed, to
help with weed control, or to incorporate
straw in the oxygen layer of the soil.
Large diameter discs ensure Rubin can
cope with set-a-side, lodged cereals,
maize stalks, or tall green manure crops.
