What Makes This Different Most "soil boosters" are a guess — a blend of inputs marketed as biology. SPE is a single, naturally-occurring material: ancient reed-sedge organic matter, fully decomposed over 10,000 years, independently DNA-sequenced to confirm 811 living microbial species. It's not simple. It's just not synthetic. Ten thousand years is hard to formulate in a lab.
Why "Fully Decomposed" Matters Fresh compost and mulch are still breaking down — like a meal still cooking. While they finish, they're actually pulling nutrients away from your plants to fuel their own decomposition. SPE skips all of that. It's already finished, so its nutrients and biology are available to your plants immediately.
Where This Helps Most Transplanting is where growers see the biggest difference — scoop a handful into the hole before transplanting anything from a seedling to a tree, alone or paired with an Organic REV root drench, for lasting soil hospitality that makes new plants feel right at home. Also ideal for seed starting and seasonal soil refreshes. [See the full use-case guide →]
How to Use
- Transplanting: Add a handful directly into the hole before transplanting.
- Established plants: Lightly aerate soil and blend SPE evenly across the top 1–2 inches.
- New plants / seed starting: Blend SPE into potting or seed starting mix at a 10–15% ratio.
- For best results: Water or foliar spray with Organic REV every 2–4 weeks to activate the biology SPE provides.
The Proof SPE is trusted across organic agriculture, vineyards, and hemp production, and by landscape professionals for 40+ years — including PGA Tour greens, professional stadiums, and World Cup turf. Independent NDSU trial data documents 25–50% reduced fertilizer needs and 15–69% yield increases across 12+ crops. USDA Organic. OMRI Listed.
