Bacteriosol
A revolutionary soil micro-biological activator. Loaded straight into your fertiliser spreader, it accelerates humus formation and recycles unabsorbed minerals already present in your ground.
Explore BacteriosolEvery SOBAC product carries the same Marcel Mézy biology and 30+ years of research. The difference is where, and how, you put it to work.

A revolutionary soil micro-biological activator. Loaded straight into your fertiliser spreader, it accelerates humus formation and recycles unabsorbed minerals already present in your ground.
Explore Bacteriosol
Transforms manure, slurry, green waste and digestate into a nutrient-rich, eco-friendly soil enhancer, more nutrients per tonne, less crusting and far better nitrogen management.
Explore Bacteriolit
The same living SOBAC biology as Bacteriosol, now in a sprayable form. Goes on through your existing sprayer for even coverage, built for arable farmers who already live on the sprayer.
Explore Quaterna SolSOBAC microbes don't feed the plant directly, they restart the cycles that feed the plant for you.
Drives nutrient cycling, capturing and recycling mineral elements already present in the soil so less needs to be bought in.
Accelerates humus formation, boosting organic matter, structure and the soil's ability to hold water and resist erosion.
Improves the root environment, encouraging deeper, healthier root systems and stronger nutrient uptake.
Most farms end up using both, Bacteriosol on the land, Bacteriolit on the muck. We'll calculate the right quantities for your acreage.

Bacteriosol is a revolutionary soil micro-biological activator developed through over 30 years of dedicated research focused on regenerating humus and enhancing soil fertility. It's a 100% natural, UAB organic-certified biological soil inoculant by Marcel Mézy Technologies.
It works by recycling unabsorbed mineral elements already present in your ground and rapidly accelerating humus formation, operating across the autotrophic, humic and rhizospheric zones of your soil for holistic, lasting improvement.
Request pricing & dataMakes existing nutrients available, optimising fertilisation efficiency and reducing what you buy in.
Stronger, more resilient crops that better withstand dry spells and disease pressure.
Encourages roots to drive deeper, reaching moisture and nutrients further down the profile.
Improves structure and aeration, reducing erosion and naturally balancing soil pH.
Enhances the nutritional quality of the crop you harvest, not just the tonnage.
A living soil self-regulates, reducing the need for corrective lime over time.
Bacteriosol is designed to replace conventional fertilisation while improving yields, so the agronomy and the economics pull in the same direction.
No new kit, no specialist contractor.
Simply load Bacteriosol into your regular fertiliser spreader, the pellets flow just like conventional product.
A typical rate is around 100kg per hectare, a single 24-tonne load covers roughly 240 hectares. We tailor the exact rate to your soil and cropping.
The microbial blend activates and works through the season, with cumulative gains year on year.

Bacteriolit is a groundbreaking solution that transforms manure into a nutrient-rich, eco-friendly soil enhancer.
Representing over 30 years of meticulous research in soil fertility and humus regeneration, it breaks organic matter down into soil-absorbable forms and works across the autotrophic, humic and rhizospheric zones for holistic soil-health benefits.
Request pricing & dataSignificantly increases the nutrient content in cattle manure per tonne, so the same heap does more.
Boosts dry matter and humic acids in the soil, feeding long-term fertility rather than a single flush.
Optimises nitrogen management in livestock effluents, holding more value where you want it.
Improves soil water resilience and structure once applied, helping land cope with wet and dry.
Prevents slurry-pit crusting and deposits, making stores easier to manage and agitate.
Enhances nutrient uptake by plants for healthier, more robust growth across the field.
Farmyard manure of all kinds.
Livestock slurry & effluents.
Plant & composting material.
Anaerobic digestion output.
Simply apply Bacteriolit directly to your manure, slurry, green waste or digestate.
As a guide, one 500kg bag treats roughly 500m³ or 400 tonnes of manure. AgrAssure calculates the exact quantities for your volumes and acreage, so you're never over- or under-treating. Available in 500kg bulk bags or 20kg bags on a pallet.

Quaterna Sol carries the same living microbes as Bacteriosol, the fungi and bacteria that build humus and recycle the nutrients already in your ground, now in a form you spray on.
It is made for arable farmers who already live on the sprayer. No spreader, no separate pass, just the regenerative biology of SOBAC applied the way you already cover your fields.
Request pricing & dataApplied through the sprayer you already run, no new kit and no specialist contractor.
A liquid pass lays the biology evenly across the field, right to the tramline edges.
Far lower production emissions than synthetic nitrogen fertiliser, measured by ADEME and AgroParisTech, while building stable humus in your ground.
The same Marcel Mézy microbes proven across SOBAC, simply in a sprayable carrier.
Accelerates humus formation and unlocks the minerals already in your soil, season on season.
No synthetic inputs, the soil-first SOBAC system you already trust on the land.
No new kit, no separate trip across the field.
Quaterna Sol goes into the sprayer you already run, ready to apply across arable ground.
We tailor the exact rate and water volume to your sprayer, soil and cropping, so every hectare gets the right dose.
The microbes establish and work through the season, with cumulative gains year on year, just like Bacteriosol.
We tailor every quote to your acreage, application method and goals. Tell us about your farm and we'll send pricing and full technical information.
