Product Description: 

The Yard Mastery Starter Fertilizer contains 12% nitrogen, utilizing premium nitrogen source ammonium sulfate, which brings a really nice steely blue-green color to turf and interacts well with the other elements in the overall blend.

This blend also contains 12% phosphorus, which is plenty to push roots in an existing lawn or stimulate rooting in your seed, sod, plug, or spring project. Rounding out the macros is 12% potassium. Here, we have opted for the premium formulation, sulfate of potash, known to have a lower salt index. As with all Yard Mastery blends, we have also included a nice amount of iron at 3% and a smattering of other micronutrients, including boron, copper, manganese, molybdenum, and zinc.

All-Natural Bio-Nite™ in Every Bag! Bio-Nite is a bio-solid filler we add to every bag of Starter Fertilizer. Bio-Nite is the same thing as Milorganite, but instead of being sourced in Milwaukee, it comes from South Florida. We can tell you that it “smells like a whole lot of success!” The good news for you is that the smell tells you that the included Bio-Nite is feeding microbes in the soil every time you apply and they love it!
