The First Compost Championship
Hosted by 
– the brand owner of SoilSmiths
– Can you make the Best, the Most Alive, Nutrient-Rich Compost in Britain?
Welcome to the Compost Cup — a celebration of the art and science of composting!
Who will create the most biologically rich, nutritionally active, and truly peat-free compost in the UK?
Could it be you?
🌱 Why Join?
Compost has been with us for centuries, yet its power is still underestimated. You, the composter, are the tip of the fork — transforming waste into life. Turning carbon, nitrogen, phosphorus, potassium, and countless other nutrients into pure gold for the soil.
This championship is your chance to:
- Prove what your compost can really do
- Inspire others to see composting as a vital climate and soil solution
- Celebrate the living biology that makes great compost truly alive
Together, we’ll show that compost is:
- A source of fertility for healthy, nutritious food
- A buffer against climate extremes
- A thriving habitat for billions of soil organisms
- A real alternative to peat
Join the movement. Share your compost. Show the world what’s possible when humans and microbes work together.
🌿 What You’ll Get
Every participant receives:
- Professional, independent lab analysis of your compost’s biology and nutrient profile
- Access to a private Compost Cup community, with weekly Zoom calls led by our team
- 20% discount on Soil Ecology Lab training courses to deepen your knowledge and skills
Each sample gives you valuable, comparable data — and every round you enter boosts your chance to win.
