What Is Organic Compost?
Organic compost is a natural soil improver made from decomposed organic materials such as green waste, plant matter, and biodegradable inputs processed through controlled composting.
Unlike synthetic fertilisers that provide short-term nutrients, compost improves the structure, biology, and moisture balance of your soil over time.
- Improves soil aeration
- Enhances water retention
- Supports beneficial microbes and earthworms
- Promotes strong root development
What Does BSI PAS 100 Certified Compost Mean?
When buying compost in the UK, BSI PAS 100 certification is the most important quality standard to look for.
This certification ensures:
- Balanced nutrients and biological stability
- Low contamination levels
- Absence of harmful pathogens
- Minimal weed seeds
Kelvin Compost’s organic compost meets BSI PAS 100 standards, ensuring a safe, consistent, and high-quality soil improver.
Why Choose Peat-Free Organic Compost?
Peat-based compost has traditionally been used in UK gardening, but peat extraction damages ecosystems and releases stored carbon.
- Protects UK peatlands and biodiversity
- Reduces environmental impact
- Supports sustainable gardening
- Delivers excellent growing performance
Our compost is 100% peat-free, made entirely from green waste with no added chemicals.
