Slurry Acidification
SyreN
- Better use of nutrients thanks to up to 70% reduction in nitrogen losses
- Additional fertilisation with sulfur and mobilization of the phosphate
- Increase in yields due to optimized use of nutrients
- Greater area coverage and fewer lanes keep plant damage to a minimum
Nutrient Management of Slurry
Stabilization of slurry by acidification with the SyreN system
Like all Vogelsang solutions, the SyreN system is as effective as it is user-friendly in terms of use and maintenance. The positioning of the acid tank in the tractor‘s front hydraulics ensures optimum weight distribution with maximum user-friendliness when it comes to replacing the IBC tank. And, of course, the control offers intuitive operation and can be combined with existing communication elements.
When fertilisation meets environmental goals
Slurry acidification system SyreN for agricultural applications
Adding sulphuric acid to slurry and digestate significantly reduces nitrogen loss during application and lowers the need for inorganic fertiliser. Since tighter nutrient regulations, this has become a clear priority. Nitrogen losses are typically high – either leaching into deeper soil layers or escaping as nitrous oxide and ammonia, with ammonia emissions being the main culprit.
The SyreN slurry acidification system can be retrofitted to both new and existing slurry tankers. It ensures nutrients are retained and available to plants under optimal conditions. Losses are comparable to injection methods, but SyreN offers key advantages when used with dribble bar or trailing shoe systems: greater working widths, fewer passes, reduced crop damage, and lower fuel and power use.
The system is also designed with safety in mind – operators are never exposed to the acid during setup or use. As a bonus, the process reduces odours – a benefit your neighbours will appreciate.
Maximum safety for your slurry spreading
In addition to optimum use of nutrients, we also consider safety in the use of our equipment of the utmost importance,
How the SyreN liquid manure stabilization system works
The liquid manure is acidified during spreading via a dribble hose or trailing shoe distributor. In a mixing chamber directly in front of the linkage, the system mixes the required amount of acid into the liquid manure. A pH meter continuously regulates the quantity of acid required. All the parts are acid-proof, from the front tank to the mixing chamber. Aside from this, everything else is just normal liquid manure technology. The driver uses the system to specify the pH value at which they want to lay down the liquid manure – usually 6. When the acid is added, the mixture starts to foam, and its volume increases significantly. This is why it is not possible to acidify the liquid manure earlier on in the process, in the tank.
