Fertilizer application depth adjustment
The fertilizer placement depth can be regulated from sowing onto the surface down to
12 cm. With cereals the normal fertilizer placement depth is approx. 8 cm. The depth is
regulated by turning the screws at the ends of the wheel support bars Fig. 14. When
turning them anticlockwise the working depth gets deeper.
It is advisable to sow some meters after the regulation in order to control the placement
depth. One and the same regulation can mean somewhat different working depths due
to different soil quality.

Adjusting the sowing depth
General
Correct sowing depth is one of the most important factors influencing sprouting. In a KL-
type machine, sowing is carried out at the moist bottom of the tillage layer. The best
guarantee of successful sowing is correctly performed tillage. Tillage must be performed
in a properly timed manner such that the crumb size in the tillage layer is adequately
refined. Excessive tillage can cause a risk of smudging or crusting.
Tillage should be performed to the intended sowing depth. Sowing depths should be
selected based on the sowed plant and ground humidity conditions. With small seeds,
