SOWING SEEDS IN ROWSSOWING SEEDS IN ROWS
➜ SEED QUANTITY: The quantity of seed is adjusted by the combination of
3 elements: number of holes on the seeding disc, size of the holes in the seeding
disc, number of sprocket teeth used.
For the number of holes you need: refer to the table of distances below:
➜PLANTING DISTANCE: see table above.
Caution: The planting distance depends on the combination
of sprocket teeth (11 adjustment positions) and the number of holes
on the disc.
The drive wheel may slip depending on soil quality and placement speed.
Therefore, the number of seeds is a guideline only.
If the transmission wheel skids, planting distances will be larger, reducing
the number of seedings. So make sure that the wheel does not slip.
Seed dispersal: Seeds are dispersed in a hole according to the direction of
the motion until they are sown, and roll on the ground.
The dispersal length varies depending on the size of the hole, the soil quality,
the seed size and can vary between 3 and 10cm.

➜NUMBER OF SEEDS/HOLE:
The number of seeds differs depending on seed size, which in turn depends on the
species and the year and the adjustment of the brush.
Therefore numbers shown in the table of distances are given as a guideline only.
Below are some examples of correspondence between discs and crops,
on the basis of one seed per hole:
