Legal regulations and increasingly extreme weather are shortening the windows available for slurry and digestate application. At the same time, rising fertiliser and diesel costs are putting pressure on farm profitability.
That’s why effective grassland and nutrient management has never been more important, ensuring livestock performance and milk yield are driven by consistent, high-quality forage.
Modern slurry technology from Vogelsang helps farmers make the most of every available window, applying nutrients efficiently and protecting soil conditions.
That’s a positive shift: improving forage quality, making better use of nutrients and supporting compliance with emissions targets and public expectations.
Standard trailing shoe systems deliver low-emission slurry application by placing nutrients directly on the soil surface, reducing contamination of the sward and improving nutrient uptake.
Vogelsang’s BlackBird trailing shoe technology builds on this with active ground pressure, ensuring the shoe consistently parts the grass and maintains close contact with the soil. It can even open the sward slightly to place slurry closer to the root zone, making nitrogen and other nutrients available more quickly.
The result is more effective fertilisation in tight spreading windows, during dry conditions and between cuts — across working widths from 7.5m up to 30m.
However, precise application in a narrow slurry band and rapid plant uptake depend on a uniform, highly flowable material.
At high application rates, one issue must be avoided at all costs: downtime caused by blockages in hoses, nozzles or distribution heads. This is especially true with challenging media such as fibrous cattle slurry, where conventional systems can quickly reach their limits even with agitation to break up floating layers.
An upstream RotaCut shredder further improves consistency by producing a more uniform slurry before distribution. Some slurry can be highly fibrous and may also contain a lot of foreign matter, which is why an inline cutter is important — to improve flowability and reduce wear or damage in the system.
As slurry moves from the farmyard to the grassland, separation is becoming more common. The Vogelsang XSplit Compact Separator reliably divides slurry and fibres into solid and liquid fractions, even with dry matter content of up to 40%. It is a practical plug-and-play option for self-driven farmers and inter-farm operations.
The separated solid material, rich in organic matter and phosphates, can account for up to 25% of the original volume. Where solids levels are high, this can significantly reduce storage demand and ease pressure at peak spreading periods. The solid material is also easier to handle, store in-field, and transport. Most importantly, it is kept out of the grassland, helping to protect forage quality and reduce contamination risk.
The liquid slurry, which remains rich in nitrogen and potash, is highly flowable and ideal for spreading using trailing shoes on grassland and for producing perfect feed! In damp weather, the slurry applied close to the roots is completely absorbed by the soil within 1–2 days and is therefore available to plants in the shortest possible time. And even in dry weather, spreading in extra-narrow tracks prevents the slurry from forming a crust and becoming embedded in the forage.
Producing high-quality grassland is not just about harvesting technology. Timing, nutrient use and application quality all play a critical role throughout the season. At the start of the year and between cuts in particular, Vogelsang’s slurry technology helps ensure nutrients are applied efficiently and where they are needed most. This supports consistent forage quality and, in turn, stronger milk, optimal growth and livestock performance.
