Sowing seed
The following should be considered when setting the drilling depth:
•
Soil type?
•
Moisture?
•
Plant residues that could cause resistance?
•
Quality of seedbed?
There are three settings that together affect the drilling depth:
1. Clips. The cips is the first and most important setting.
2. Coulter pressure. Do not use more coulter pressure than the conditions in the soil
require. Usually 50 bar is sufficient to ensure good seed sowing. In dry and difficult
conditions and/or for deep seed sowing it may be appropriate to increase the coulter
pressure.
3. Positioning of the wheel The
coulter arm wheel can be set to
four (4) positions. For normal
drilling depth ( ~1 - 5 cm) no
adjustment needs to be made. If
~
you are sowing peas or beans,
or deeper sowing is required
(e.g. early summer dry soils(,
the results may be better if all
of the coulter arm wheels are
used. Refer to the image below.
•
The sowing table below is only a recommendation! Something to START with!
•
The seed sowing MUST be studied and decided in the field! Ascertain the seed amount and measure the
sowing depth!
•
Too high a fan speed will result in uneven depth of sowing.
•
Too low a fan speed will increase the risk of the seed blocking the seed hoses.
•
It is also important to check to ensure that the correct seed amount is being put out in the field (therefore
that the calibarion was correct). Advise If the actual sown amount in the field is, for example, 10 % too
high, increase the pulses per kg by 10 %.
