UK SOBAC Supplier · Since 2021

Healthier soil.
Stronger crops.
Less spent on inputs.

AgrAssure is the official UK partner for SOBAC. Our biological activators, Bacteriosol and Bacteriolit, make the soil beneath your feet live, so your land does more of the work and your chemistry bill does less.

30+ years of research 300,000+ ha proven 30 to 50% less nitrogen
Microbiological activity in regenerated soil
28,000+microbial DNA strains per bag
Regenerative farming that pays

Your soil is an ecosystem. We make it live.

Decades of intensive chemistry have left many soils chemically fed but biologically lifeless. SOBAC products reintroduce the microbial cycles that traditional fertilisers deplete, so nutrients already locked in your ground become available again, naturally.

  • Recycles unabsorbed minerals already in your soil
  • Accelerates humus formation and water retention
  • Builds deeper roots and drought resilience
About AgrAssure
Two products. One living system.

Choose your starting point

Whether you're feeding the soil directly or making more of the manure you already produce, there's a SOBAC activator for it.

Bacteriosol

A micro-biological activator that goes straight through your fertiliser spreader. It accelerates humus formation and unlocks the nutrients already in your ground, the future of soil fertility.

Bacteriolit

Transforms manure, slurry, green waste and digestate into a richer, more stable soil enhancer, more nutrients per tonne, less crusting, better nitrogen management.

Soil regeneration

Better results, year on year, not just one good season

SOBAC introduces over 28,000 species of microorganisms that break down organic matter, build humus and make nutrients available. The result is a balanced, thriving ecosystem under every acre.

  • Eliminate the need for Lime, P and K
  • Cut nitrogen use by 30 to 50%
  • Visible change in months; transformation over ~3 years
The science of regeneration
Simple to adopt

From first spread to lasting change

Talk to us about your land

We calculate quantities around your acreage, soil, crops and application method, no guesswork.

Spread it with a standard fertiliser spreader

Bacteriosol loads into a standard fertiliser spreader, the kit you already own; Bacteriolit goes onto manure, slurry or digestate.

The biology gets to work

Microbes activate three soil zones, autotrophic, humic and rhizospheric, recycling minerals and building humus.

Wind back the chemistry

As soil health returns you reduce synthetic inputs, fuel and passes, protecting both margin and land.

Why biology beats more chemistry

Two ways to farm the next decade

Input-dependent farming

  • Rising spend on N, P, K and lime every year
  • Soil biology depleted, structure declining
  • Poor water retention, more drought stress
  • Higher emissions, exposed to input prices

Regenerative with SOBAC

  • 30 to 50% less nitrogen; drop P, K and lime
  • Living soil that recycles its own nutrients
  • Deeper roots, better water holding, more resilience
  • Carbon sequestered, gross margins improved
From the field

“By cutting the nitrogen our yields did not drop, which was the big fear. The crop is utilising the nitrogen being created in the humus, exactly what we hoped.”

Open days that fill the shed

Regenerative farming isn't a theory here, it's a growing community. Our open days bring over 100 farmers together to dig real soil pits, compare results and see the SOBAC system in the field.
