Natur Composter
Compost accelerator — two-component microbial preparation
A two-component microbial compost accelerator: cellulose-degrading bacterial strains and a lignin-degrading fungal additive. It speeds up the breakdown of leaves, crop residues and woody prunings, in garden and farm-scale compost alike.

Product description
Natur Composter
Compost accelerator
A two-component microbial preparation for faster compost maturation. The cellulose-degrading strains of the bacterial component and the lignin-degrading species of the fungal component work together to process leaves, crop residues and woody prunings. Suitable for home gardens, orchards, vegetable growing and arable fields alike.
Composition
Bacterial component (min. 2×10⁹ CFU/cm³): Paenibacillus macerans, Paenibacillus amylolyticus, Paenibacillus polymyxa, Cellvibrio flavescens
Fungal component (5×10⁶ CFU/cm³): Trichoderma harzianum, Phanerochaete crysosporium, Flammulina velutipes
Mechanism of action
- Compost acceleration — cellulose-, hemicellulose- and lignin-degrading capacity; it also processes hard-to-decompose woody material
- Residue decomposition — stem and root residues break down within 4–5 months
- Nitrogen fixation — fixing atmospheric nitrogen (40–60 kg N/ha/season)
- Phosphorus and potassium mobilization — releasing bound reserves and the nutrients of plant residues
- Biocontrol — Trichoderma harzianum suppresses soil-borne pathogenic fungi
- Soil structure — forms EPS aggregates → improved water retention and drought tolerance
Application guide
Dosage for compost
Per cubic metre, mix 200 ml of the bacterial component with 100 ml of the fungal component (2:1 ratio) and dilute with at least 5 litres of water.
| Compost | Bacterial component | Fungal component | Dilution water |
|---|---|---|---|
| 1 m³ | 200 ml | 100 ml | min. 5 L |
| 5 m³ (1 L + 0.5 L pack) | 1 L | 0.5 L | min. 25 L |
| 10 m³ (2 L + 1 L pack) | 2 L | 1 L | min. 50 L |
The treatment can be repeated monthly until the compost is finished.
Application to compost
- Spray or pour the prepared mixture onto the plant residues within 1–2 hours
- Work in calm weather, without direct sunshine, between 10 and 20 °C
- The optimal pH range is 5.5–7.0
- Do not use high-pressure sprayers, as they damage the microorganisms
Arable and horticultural doses (bacteria + fungus together)
| Use | Dose (total) | Water requirement |
|---|---|---|
| Manure/compost treatment (per 20–50 t) | 3 / 4.5 / 6 L/ha | min. 20 L/ha |
Breakdown of the dose levels
- 3 L/ha: 2 L bacterial component + 1 L fungal component
- 4.5 L/ha: 3 L bacterial component + 1.5 L fungal component
- 6 L/ha: 4 L bacterial component + 2 L fungal component
Important information
- Minimum soil temperature: 6 °C
- On arable land, incorporation within 24 hours is required
- Do not mix with copper- or zinc-containing plant protection products
