Product Description
Greenway Biotech Ammonium Sulfate Fertilizer 21-0-0
Greenway Biotech ammonium sulfate lawn fertilizer is a water soluble fertilizer providing 21 percent nitrogen by weight and 24 percent sulfur. The guaranteed analysis is 21-0-0. It can be applied to lawns as a top dressing of nitrogen and sulfur with a broadcast or drop-type spreader. In areas with high pH soils, the sulfur in ammonium sulfate helps lower soil pH levels. As with other fertilizers, water the treated area well after each application.
Greenway Biotech Ammonium Sulfate Fertilizer 21-0-0
Ammonium Sulfate is a compound crystalline in nature used primarily in the manufacture of artificial alkaline soil fertilizers for agriculture. This compound is an inorganic water-soluble salt that contains 21% Nitrogen and 24% Sulfur.
As a water-soluble fertilizer, Ammonium Sulfate is extensively used for crop production because it provides efficient nitrogen and readily-available sulfur which aid in plant growth. This fertilizer is paramount in the maintenance of healthy soil and vibrant crop growth by adding general value to alkaline soils.
In fact, Ammonium Sulfate's high nitrogen content is what makes it the perfect supplement for nitrogen deficient soils and lawns, alike. Since lawn grass requires nitrogen, commercial lawn fertilizer products use ammonium sulfate to stimulate the quick growth of grass turf and healthy lawn grass.
And since ammonium sulfate for blueberries easily blend with other nitrogen fertilizers, they allow for a more stable dry lawn fertilizer. But you'll want to exercise greater caution when using Ammonium Sulfate fertilizers as they can elevate soil acidity to extreme levels that could adversely affect grass or crops.

It mixes very well in water and after about a months use of this stuff, it appears to be helping my blueberry bushes grow a lot. I used one teaspoon of this stuff in 2 gallons of water twice a week per bush. They weren't growing much before, but now they are growing like crazy.
It also appears to green up my Bermuda grass (I did a little test on a patch of grass), although I probably wouldn't use this for your lawn unless you have alkaline soil.
Overall, this is some great stuff. I highly recommend it.
