For some reason, Scotts makes it very difficult to find the NPK ratio of their fertilizers, without physically looking at the bag, but this is a 20-0-8, with Biferin added for insect control. You have to go to the Product Details page, and pull up the enlarged image of the package to find the NPK. I could not find it listed anywhere else in the product information on Amazon. This is a good NPK for warm season grasses, and adding the Biferin is a good idea. It's only about a quarter percent by volume, and whether that's enough to matter, I don't know, but it can't hurt, and this is a good price.

Edit — just went to purchase and it's unavailable to me. Oh well.

It should be fine for St Augustine. 20 percent nitrogen is not super high compared to a lot of lawn fertilizers, so not as dramatic a green up, but it would still feed St Augustine just fine. It has no Phosphorus, but you may not need it, if you've used a fertilizer containing phosphorus recently. Phosphorus stays in the soil the longest. Nitrogen washes out almost immediately with a good rain, and Potassium a little slower, but not like phosphorus.
