6.7. Calibration test
The seeding tables that contain the basic values for adjusting the seeding quantity are located
under the transmission cover in the seed and fertiliser drill. The seeding tables are provided in
section 6.4. SEEDING QUANTITIES. However, there are great differences between various seeds,
which is why the actual seeding quantity must always be checked with a calibration test. Seed
treatment, such as seed dressing, has considerable impact on uidity.
The calibration test should be performed whenever changes are made to the feeding quantities.
In particular, fertiliser quantities may vary a lot due to the moisture and uidity of the fertiliser.
When driving on the road with hoppers full of fertiliser and seeds, the vibration may cause
arching in the hoppers. In the autumn or after rain, the fertiliser may absorb humidity in the
feeders, changing fertiliser uidity. For this reason, it is good to monitor that fertiliser or seed
ow evenly from all feeders when seeding begins. Performing a calibration test is in order and
visually checking that the feed quantity is even in all feeders.
