    Potassium Nitrate

    Very good price. Great company to buy from. As for the potassium nitrate it looks clean and pure. I use it in my compost and to speed the decay of stumps so I can only assume it will work as good as any.

    Better than expected

    VERY clean! Nearly pure from what I can tell. Love that it's in a fine powder form as opposed to pellets. Meters perfectly in my applicator without binding or sticking. Will DEFINATELY be ordering again when needed!

    It was very easy and reasonable to purchase the Potassium Nitrate which I use for seed soaking, foliar sprays, and more to encourage fruit production and flowering and germination
