BritBerry™

Precision Substrates for Commercial Berry Production

Explore crop-specific coir substrates for strawberry, blueberry and raspberry. Match water, air and drainage to your growing system, with formulation guidance and grower trials.

WHY BRITBERRY?

The substrate beneath the crop matters.

Strawberries, blueberries and raspberries have different root architectures, crop durations, irrigation strategies and production systems.

BritBerry™ doesn't treat berry substrate as one universal formulation.

We engineer crop-specific root-zone solutions around particle structure, water availability, aeration, drainage, crop duration and the grower's production system.

SUBSTRATE SCIENCE

Engineering the root zone.

The physical behaviour of a substrate is determined by more than its ingredients.

Particle size, particle distribution and the balance between coco peat, fibre and chips influence water availability, air-filled porosity, drainage and structural stability.

  • Water retention
  • Moisture distribution

COIR FIBRE

  • Structure
  • Pore connectivity
  • Root-zone aeration
