Potassium Nitrate HIGH Purity Milled Reagent Grade 4 LBS 4 POUNDS

Let me get this part out; I hate the packaging. Just not a fan as I can’t fold the bags as I do with other products in the P-Tech world.Outside that, great product. You may have to screen a bit to pull clumps or some bigger particle sizes, but for anyone making B/P this is pretty pure. You probably are good without even boiling. Kills the “Tech grade” stuff on the P-Tech market. Try boiling a small batch, as you should with any BP you acquire. Super easy to compare the residual here vs competition and with a decent price. Everyone knows what you end up paying for similar products and how little you get. I’m impressed. Love their Sulfur and air float as well. Their online store has some good products. Glad to see it here.

Works great as a stump buster. Drilled holes into a 3' diameter stump and poured in the powder - 4 months later it was easily removed.

Works very well in everything I have used it for.....

Good quality, decent price. Only gave it 4 stars because the packaging failed on one of the corners and spilled out into the shipping box.

I have a stump less than 6' from my house in an inside corner where the store room joins the utility room. All that to say that it was too close for a stump chipper. The stump was from a 70' red oak that I had cut down because it was too close to the house. I had it cut down ten years ago . A year ago it hadn't rotted out, so I put this stuff on it and it is half gone. Now I need to get the rest out of there. Then eventually I will have a huge hole to fill. Oh well. The never ending story. I didn't have enough to do two much smaller stumps in from from Bradford Pears. Beautiful trees, but derecho bait. I ordered another bag just now. Great stuff. Oh up above it asked me to rate it for sheerness and thickness. Got no idea what they mean, but if they mean granual size it was not dust but pretty fine.

Nice big bag . More than four pounds. It can be used to feed plants or to over feed and kill them. In my area some places get overrun with multiflora rose. It's like living concertina wire. I've been fighting some on my property for several years and I started using potassium nitrate to overdose them with nitrogen and screw up their system. It seems to be working so far. My theory is , if you gradually get way too much of it in their root system, the chemistry gets so out of balance that they can't absorb nutrients. I won't really know if it has been truly successful until next summer. For now, they look as dead as door nails. I don't want to use hormone disrupting herbicides if I can help it.

Was great for making color smoke flares.

Purchased this to dispose of some old tree stumps, drilled a few holes in each and filled with this powder. The powder was finely ground with a few clumps. I can already tell the tree stumps are decomposing the stuff works great
