    High sulfur to raise acid level

    By Daniel on 12/03/2021

    This stuff works very well when trying to raise the acidity of your lawn soil. If you have take all root rot in your lawn this is what you want to raise the acidity of the soil and kill the fungus. You can use this in conjunction with antifungals. It works very fast. I have sandy soil with St Augustine and it turned my lawn around with one application. the second application a month later and since has been gone. I did spray Propiconazole in between applications to help. Very happy with this product.

    Local stores don't stock it in quantity

    By Edward on 05/15/2020

    On line is a good way to buy since it would be much slower to have a farm supply order it for you plus your travel and time costs. Received promptly amidst the Wuhan virus pandemic.

Q
Is Hi-Yield Ammonium Sulfate 21-0-0 water soluble?

Don’t see the answer on the label. Other manufacturers of this same product listHi-Yield Ammonium Sulfate 21-0-0 as water soluble. I want to spray .25lb per 1000 sqft which would work out to about 1.19lb per gallon of water?

A

Hi-Yield Ammonium Sulfate 21-0-0 is activated by water, but it is not labeled to be mixed with water and then sprayed. You may contact the manufacturer for further information:

Q
What is the spreader setting for a Scott's Edge using Hi-Yield Ammonium Sulfate 21-0-0?
A

Unfortunately, we do not have the spreader settings for most specific spreaders and the manufacturer does not list that spreader on their bag. Due to the thousands of granules on the market and just as many different types of spreaders, you will want to calibrate your spreader to the product you are using and its application rates. You can see a short video on how to accomplish this below.
