Pure Original Ingredients Ammonium Sulfate (8 oz) Soil Acidifier, Inorganic Sulfate Salt

I use this for acid dyeing on wool to help control how the dye strikes. Works well for me.

Bought this to treat the soil of the citrus trees. Their leaves are either yellowish or falling. Anyway, after diluting in the one gallon water of one tablespoon of the product, I watered around the trees. It's been over a month so far, I haven't noticed anything different. Checked the soil PH value, did not see the needle move from alkaline to acidic. With such a small quantity, I will run out pretty quickly just to treat two trees.

Draw on chemistry class kids! 1 tsp per glass of water. For a 10" pot, that is enough to drop alkaline level by 1 - 1.5 level . DO NOT over use - - - tomato plant will go into shock. Great for hydragenias from pink to blue

It gave me blueberries when they were all small and green. If i used it beforehamd i wouldve gotten way better berries. 5 stars

Well packaged and the option of a half pound size was great.

Great Item

This is the smallest package I've ever seen making it's excuse for fertilizer. Enough to fertilize a one quart planting pot. Ridiculous.
