Smarter Soil

Use your Smarter Soil DIY test kit to measure nitrogen (N), phosphorus (P), potassium (K) and pH from your own plot. Open the app, enter your results, and get instant guidance - matched to what's actually in the ground beneath you. Smarter Soil helps allotmenteers, home-growers, and gardeners make soil health simple, visual and actionable - helping to grow healthier plants and more resilient plots. 300+ PLANT SOIL PROFILES: Explore a database of commonly grown UK plants, each with its own optimal soil properties across the five pillars of soil health: pH, nitrogen, phosphorus, potassium, and moisture. TRACK YOUR PROGRESS: See how you soil improves over time and how it affects plant growth and yield. FIX IT NATURALLY: • Get tailored amendment recommendations based on your results and what you want to grow • Suggestions use natural inputs -> compost, manure, wood ash, and more • Know not just what's missing, but how to fix it before you sow GROW SMARTER, NOT HARDER: • Companion planting tips to get more from every square metre • Soil education built in -> learn why nutrients matter, not just what to add • Build real knowledge about your plot over time PERFECT FOR: • Allotment holders getting serious about their yields • Home gardeners tired of trial and error • Beginners who want a reliable, science-backed starting point • Anyone who's ever wondered why their tomatoes underperform WHY IT MATTERS: Plants are precise. A brassica and a blueberry want completely different things from the same patch of earth. Smarter Soil helps you stop guessing and start matching your soil to what you want to grow, then tells you exactly how to get there. Dirt has a PR problem. We're fixing it.
