Silage Additives

Silage Additives for Grass Silage, Maize Silage and Biogas Plants

When purchasing silage additives, correct application and accurate dosage are essential. Silage additives significantly improve the quality of grass and maize silage and are indispensable for modern biogas plants. Choosing the right silage additive helps minimize losses and increases the storage stability of your silage.

Whether for grass silage or maize silage, the use of silage additives is a key step in producing high-quality, nutrient-rich silage. Discover our range of premium silage additives and learn more about correct dosage and application.

What are Silage Additives?

In brief: Silage additives are supplements that improve the fermentation process of silage, reduce nutrient losses, and ensure stable, high-quality forage.

Silage additives optimize fermentation by inhibiting undesirable microorganisms while promoting lactic acid bacteria. This leads to improved nutrient preservation, better silage stability, and reduced dry matter losses.

They are particularly beneficial for grass silage, maize silage, and biogas plants, as they can increase efficiency and energy content. Silage additives play an important role in animal feeding and biogas production by improving overall yield and end-product quality.

Silage Additive Comparison: AGRIsil G, M and BG

Depending on the intended use — grass silage, maize silage or biogas plants — AGRIsil offers the right solution. The overview below helps you choose the appropriate silage additive.

*Exact dosage depends on harvesting method, throughput per hour, and nozzle capacity. Always follow the manufacturer’s instructions.

Application during the ensiling process is straightforward and efficient, saving both time and effort. Choose AGRIsil and benefit from a reliable product that sustainably improves your yields.

For over 30 years, we have been supplying farmers, agricultural contractors, and biogas plant operators across Europe with high-quality silage additives and agricultural products.

Benefits of Silage Additives for Forage Preservation

Silage additives (also known as silage supplements) are used during the ensiling process to improve fermentation, minimize nutrient losses, and ensure high forage quality. Depending on the type, silage additives can have different modes of action. There are biological additives (e.g. lactic acid bacteria) and chemical additives (e.g. acids or salts).

Below is an overview of the key benefits of silage additives:

1. Improved Fermentation
   • Promote rapid pH reduction through lactic acid formation
   • Suppress undesirable microorganisms (e.g. clostridia, enterobacteria)
   • Result: Stable, high-quality silage with fewer fermentation failures
2. Preservation of Energy and Nutrients
   • Reduce losses of sugars, protein, and energy during fermentation
   • Minimize dry matter losses (DM losses)
   • Result: More nutrient-rich forage with improved digestibility
3. Better Feed Intake and Animal Health
   • Improves palatability due to stable, lactic acid-based silage
   • Reduces the risk of butyric acid fermentation, which can cause feed refusal or digestive issues
   • Result: Higher feed intake and stable milk yield
4. Improved Aerobic Stability
   • Certain additives (e.g. propionic acid, homofermentative lactic acid bacteria) inhibit yeasts and moulds
   • Result: Silage stays fresh longer after opening, with reduced secondary heating
5. Support under Challenging Ensiling Conditions
   • Especially beneficial when:
     • Silage is too dry or too wet (unfavourable dry matter content)
     • Forage contains low sugar levels (e.g. legumes)
     • Using small silos or during long filling times
   • Result: Reliable fermentation even under difficult conditions

Tips for Correct Application of Silage Additives

Silage additives play an important role in producing high-quality silage for grass, maize, and biogas plants. Follow these best-practice tips:

1. Observe correct dosage: Always apply the recommended amount. Underdosing reduces effectiveness, while overdosing causes unnecessary costs.
2. Ensure even distribution: Apply the additive uniformly across the entire forage mass for optimal results.
3. Apply early: Apply the silage additive directly during filling of the silo to ensure rapid and uniform fermentation.
4. Choose the right product: Select the appropriate silage additive based on crop type and conditions. Different products are optimized for grass, maize, or biogas use.
5. Proper storage: Store silage additives in a cool, dry place to maintain effectiveness.

Correct Silage Additive Dosage

Always follow the specified dosage instructions when applying silage additives. Dosage varies depending on the intended use:

• Grass silage: Dissolve 2 g AGRIsil G per tonne of forage in 3–5 litres of water, apply 0.2–2.0 l per tonne of forage
• Maize silage: Dissolve 2 g AGRIsil M per tonne of forage in 3–5 litres of water, apply 0.2–2.0 l per tonne of forage
• Biogas plants: Dissolve 1.5 g AGRIsil BG per tonne of forage in 5–10 litres of water, apply 0.2–2.0 l per tonne of forage

The degree of dilution depends on harvesting method, throughput per hour, and nozzle capacity. The recommended water temperature is 18–30 °C. The prepared application solution is ready for immediate use and should be applied within 48 hours.

Important: The silo should remain closed for at least 6–8 weeks.

Correct silage additive dosage is essential for successful application — especially if you use silage additives to actively improve silage quality.
