Disc injector
The Bomech Disc Injector places the slurry directly into the soil through rotating discs, with minimal soil disturbance. Nutrients are available to the roots straight away, while surface losses and odour emissions are kept to a minimum. Its compact design and low weight let it mount easily on any slurry tanker.

Everything you need to know about the Disc Injector
The Bomech Disc Injector combines precise slurry placement with minimal soil disturbance. By injecting the slurry directly into the soil through rotating discs, nutrients are immediately available to the roots while surface losses and odour emissions are kept to a minimum. This ensures maximum nutrient efficiency, even under challenging weather or crop conditions.
Its lightweight and solid construction keeps maintenance to a minimum while ensuring reliable performance in all conditions. Each pair of discs is individually suspended, allowing optimal contour adjustment and a consistent working depth, even on uneven terrain.
Thanks to its compact design and low weight, the Disc Injector is suitable for various soil types and can be easily mounted on any slurry tanker. Further features:

For extra flexibility and demanding conditions, the applicator offers the following:
- The Alrena precision macerator with 50 mm drain hoses ensures uniform distribution to every outlet.
- Specialised rubber nozzles place the slurry directly into the soil for targeted nutrient delivery.
- Minimal leaf contamination, so the crop stays clean.
- Each pair of discs is individually suspended for a consistent working depth.
- Transport width of only 2.80 m on both working widths.
- Lightweight and solid construction that keeps maintenance to a minimum.

How does injection differ from a trailing shoe?
A trailing shoe places the slurry on the soil under the crop; the disc injector cuts the soil open with rotating discs and places the slurry inside it. Nutrients are immediately available to the roots, and surface losses and odour emissions are kept to a minimum.
Does it disturb the soil a lot?
No. The machine combines precise placement with minimal soil disturbance. Each pair of discs is individually suspended, which allows optimal contour adjustment and a consistent working depth, also on uneven terrain.
How is the slurry divided across the outlets?
By an Alrena precision macerator with 50 mm drain hoses, feeding 32 outlets on the 6.4 m and 36 on the 7.2 m at 20 cm spacing. Specialised rubber nozzles place the slurry directly into the soil.
Which soil types is it suitable for?
Various soil types. Thanks to its compact design and low weight, from 1,050 kg, it can be mounted on any slurry tanker and stays workable where a heavier machine would be a problem.
Why is the working width smaller than on the other machines?
Injecting takes more traction than surface application, so the working width of 6.4 or 7.2 m is matched to what a tractor can pull through the soil. The transport width of 2.80 m keeps road travel simple.
How much slurry ends up on the crop?
Very little. Because the slurry goes into the soil rather than onto the surface, leaf contamination stays minimal, which helps forage quality and reduces odour after application.
