Is it just gypsum (calcium sulfate dihydrate) or are there other chemicals/fertilizers added to this product? I want an ingredients list
Asked by: Corey
Hello, Pennington Fast Acting Gypsom is 96.5% gypsum. It also contains Advanced Soil Technology (AST). AST helps by binding nutrients to the soil which prevents them being lost by the runoff of surface water. Thank you

What if I have standing water in areas of my lawn? Can I apply in those areas and it still produce the same result or do I need to wait until the standing water subsides?
Asked by: Matt
If you have no risk of rain running it off, yes. It will be more effective if you let most of the water evaporate.

Will this product help the soil that is damaged by road salt

Will this product help the soil that is damaged by road salt
Asked by: Westy
Hi Westy, Gypsum can help leach the salt away from the top levels of the soil, as it can make soil more porous. However, it will need to be heavily watered in order to do this. Thank you.

Rated 4 out of 5 by from very necessary for my soil well honestly what can you really say about gypsum? it came super fast with free shipping. it breaks up clay so that your water gets to the roots of your lawn or garden. it was very easy to order without having to go search for it at my local store which never has anything i want anyway. i love home depot online.

Rated 4 out of 5 by from Works as designed It takes a couple of applications over a few months to really start seeing the difference but it is a great product to use in the summer when regular fertilizer would burn the grass. Suggest that frequent watering would push along the soil enhancement even further.
