Scotts Turf Builder ingredients help grass grow thicker.

Scotts Turf Builder Ingredients

by Peter Mitchell

Sure, you want to keep your lawn lush and soft for the kids to roll around on. But, it helps to know what's inside your fertilizer before you start sprinkling granules all over the yard. Scotts Turf Builder ingredients include substances that could harm your little ones -- including urea and manganese oxide. If you use it sensibly, and keep the package away from children, then you can get healthy lawns without health hazards.

Basic Ingredients

The U.S. government's Household Products Database lists the ingredients of standard Scotts Turf Builder as urea, manganese oxide, ammonium phosphate monobasic, potassium sulfate, ferrous sulfate heptahydrate, ammonium sulfate, manganese sulfate anyhydrous and nuisance dust. If you're like most people, then those names won't mean a whole lot. But substances such as urea contain lots of nitrogen, an element that can help turf grow strong and healthy.


Nitrogen-rich urea makes up at least 60 percent of Scotts Turf Builder ingredients. Ammonium sulfate makes up 10 to 13 percent, potassium sulfate up to 10 percent, and sulfur up to 13 percent. These contain some of the key minerals and elements that make up many fertilizers -- nitrogen, phosphorus and potassium.

Harmful Effects

Some Scotts Turf Builder ingredients can cause harm if they come in contact with eyes, mouths or little hands. Needless to say, the advice on the back of the pack is to keep the fertilizer away from children. It's worth keeping the kids off the lawn for a while after spreading the granules. If you or any family members suffer from allergies, such as asthma, take extra care when handling the fertilizer, and avoid opening it in confined spaces.


If Scotts Turf Builder gets into an eye, rinse gently with fresh water for around 20 minutes. Similarly, if it touches your skin, then rinse it off with cold water. If you or your kids accidentally eat some of the granules, it can cause vomiting and diarrhea. Call a doctor or speak to advisors at your local Poison Control Center as soon as possible. It's not recommended to induce vomiting, but sipping a little water is OK.


Scotts offers a few variations of their Turf Builder range, with slightly different ingredients and relative mineral content. For example, the Turf Builder Starter Food for New Grass contains 24 percent nitrogen, 25 percent phosphorus and 4 percent potassium. Turf Builder Weed and Feed, however, contains 28 percent nitrogen, 0 percent phosphorus and 3 percent potassium. The type you choose should depend on the age, condition and type of lawn you own.
