Description

Crustacean Meal is a unique, marine-derived fertiliser made from the shells of crabs, prawns, and lobsters — dried and processed through our custom equipment to yield a pasteurised, graded product that's clean and ready to use straight in the garden. This is the crème de la crème of soil ingredients: while some vendors offer discarded remains at premium prices, or worse, factory-farmed imported shrimp passed off as crustacean meal, ours comes from a food-grade source first, then undergoes our full custom drying and processing chain.

The standout feature is chitin content — significantly higher than insect frass — which elicits a systemic acquired resistance (SAR) immune response in plants, helping to protect them from pests, diseases, and environmental stresses. Alongside the chitin, crustacean meal delivers 20% calcium for strong cell walls and improved plant structure, plus a slow-release NPK feed that breaks down gradually over time. It's a genuine multi-purpose amendment that builds both fertility and plant resilience simultaneously.

5 - 2 - 0.1

Nitrogen (5%), Phosphorus (2%), Potassium (0.1%), Calcium (20%)

Provides NPK and calcium from a marine source, plus high doses of chitin (more than frass).

Mix 8–12 g per 5 L of soil when building your mix. The chitin content supports pest defence and feeds fungal biology. Work in at the start of a cycle.

Soil people, same as you.

Soil Supply Co. started because we got sick of paying premiums for inputs that under-delivered. If we wouldn't put it in our own soil, it's not on the shelf.
