Legal regulations and increasingly extreme weather conditions – such as long periods when fields are impassable due to excessive rain or extreme drought and heat – are resulting in ever-shorter windows for spreading slurry or digestate. Rising fertiliser and diesel prices are also putting further pressure on profitability.
This makes it all the more important that livestock, milk and mast yield can benefit from perfect forage without compromise. Modern slurry technology from Vogelsang plays a key role here!Vogelsang’s optimised BlackBird trailing shoe technology, with active ground pressure, not only reliably parts the vegetation during spreading, thereby preventing forage contamination, it even slots through the turf, depositing the slurry close to the roots and making nitrogen and other nutrients available to the plants as quickly as possible – ensuring optimal fertilisation results during short application windows, extreme drought and between summer cuts. And all this across working widths from 7.5m to 30m!
However, precise application in as narrow a slurry swath as possible and the fastest possible uptake by the plants require a homogeneous medium with maximum flowability. Because when working at maximum output, there is one thing that must be avoided at all costs: interruptions and standstill caused by clogging of hoses, nozzles and distributor heads! Particularly with demanding media such as cattle slurry with a high fibre content, conventional technology often reaches its limits despite agitating the floating layers.
As liquid manure makes its way from the barn to the grassland, liquid manure separation is becoming increasingly common. The XSplit Compact Separator from Vogelsang, for example, reliably separates the solid and liquid suspension phases of slurry and digestate, even with a dry matter content of up to 40%! A good choice as a plug-and-play solution for self-mechanised farmers or for inter-farm use.
The dry fraction separated out in the process, rich in organic material and phosphate compounds, can account for up to 25% of the volume! Particularly where the solids content is high, separation can save a massive amount of storage capacity and provide relief at the end of the storage period! Furthermore, the dry phase is straightforward to store on the field and easy to transport. And most importantly: the separated material never ends up on the grassland and does not cause contamination of the forage!
The liquid suspension, which remains rich in nitrogen and potash, is highly flowable, homogeneous and ideal for spreading using trailing shoes on grassland and for producing perfect feed! In damp weather, the liquid manure 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 liquid manure from forming a crust and becoming embedded in the forage.
Producing the perfect forage isn’t just down to the best harvesting technology. Especially at the start of the season and between harvests, Vogelsang’s sophisticated slurry technology helps ensure perfect forage and, consequently, the best milk and mast yields!
