Why should nitrogen losses be minimized when spreading manure?
Nitrogen losses are harmful to the environment.
Nitrogen losses are costly: they increase the need for artificial fertilizers (cattle manure, for example, contains approx. 3.5 kg of nitrogen per cubic meter, which corresponds to a value of approx. €6.00 per cubic meter).
What are the main factors influencing nitrogen losses?
Most farmers believe that the greatest loss of nitrogen occurs when manure is spread and flies through the air. In fact, however, evaporation mainly takes place between the time the manure is spread and the time it seeps into the soil or is worked into the soil.
An important goal in manure spreading is therefore to slow down evaporation. To achieve this, it is important to choose a favorable time for spreading the manure (ideally: low temperatures, little wind, shortly before precipitation/incorporation). It is also important to use the right technology. The best-known and most effective technique for this is to spread manure using drag hoses. This greatly reduces the surface area of the manure and significantly slows down the evaporation process. Another often overlooked but very effective aspect can also be achieved with the MÖSCHA swivel distributor.
How does the MÖSCHA swivel distributor help minimize nitrogen losses?
Thanks to the geometric shape of the swivel head and the deflection of almost the entire slurry jet, the swivel distributor patented by MÖSCHA produces very large droplets. The larger the droplets, the better the nitrogen is protected from evaporation.
It follows that: With twice as large drops, the drop surface area per content is halved, resulting in significantly less nitrogen evaporation.
It follows that twice as large drops result in half the drop surface area per content and thus significantly less nitrogen evaporation.
However, to ensure that the slurry lands on the ground in large droplets, its impact speed must not be too high.
This is illustrated in the following graphic: (Fall height 3 cm, 30 cm, 60 cm → increasing impact diameter)
With the MÖSCHA swivel distributor, the droplets are released at a reduced speed in an almost horizontal direction:
Exit velocity at the nozzle: 11.6 m/sec corresponds to 42 km/h
Exit speed from the swivel head: 8 m/sec corresponds to 29 km/h
This is a clear advantage over impact plates, as it is the only way to achieve a large-drop spray pattern and thus slow down nitrogen evaporation.
What other advantages does the large-drop MÖSCHA slurry distribution system offer?
The reduced surface area and resulting improved weight-to-surface ratio also ensure significantly better distribution in crosswinds (see also DLG test).

| Type | Edge length (d)Surface area | (d²) | Volume (d³) | Ratio |
|---|---|---|---|---|
| small | 1 cm | 6 cm² | 1 cm³ | 1 : 6 |
| twice as large | 2 cm | 24 cm² | 8 cm³ | 1 : 3 |
In addition, wetting/soiling and thus damage to the plants is significantly reduced. MÖSCHA therefore recommends spreading manure on grassland when the crop height is approx. 10 cm. Leaf contamination is low and nitrogen losses can be further reduced (protection of the manure from sun and wind).
Conclusion: The MÖSCHA swivel distributor is the best solution, especially for grassland!
