Good Batch™ Potassium Nitrate is 99.9% pure KNO3 in a 5 lb resealable pouch. It's made for stump removal, and it also works for hydroponics, plant and soil use, and lab and technical applications. The granules dissolve easily for clean, consistent results.
- Stump removal: use the drill-and-fill method to speed up the natural breakdown of old tree stumps. Pour into the drilled holes, add water, and keep the stump damp.
- 99.9% pure: high-purity granules for anyone who needs clean, consistent material.
- Multi-purpose: also used for plant and soil care, hydroponics, and lab and technical projects.
- Resealable pouch: clean storage and easy handling.
Safety: potassium nitrate is an oxidizer. Never light a treated stump, keep it away from flames and fuels, and store it sealed in a cool, dry place out of reach of children.

How to use it
Cut the stump as low to the ground as you safely can.
Drill holes 8–12 inches deep, about 3–4 inches apart, plus a few angled holes in the sides.
Fill each hole with potassium nitrate, then slowly add water to dissolve it.
Cover with a tarp and keep it damp. In about 4–6 weeks, break the soft wood apart.
