ProPEAT 13-5-8 Carbon 90 Plus Fertilizer

Professional Turf & Landscape Fertilizer

ProPEAT 13-5-8 Carbon 90 Plus Logo
NATURAL & ECO FRIENDLY - Carbon90PlusTM minimizes leaching by binding nutrients to naturally occurring carbon. That’s good for plants, good for business, and good for the environment.
SMARTER PLANT GROWTH - Carbon90Plus is a natural, extended release fertilizer which bonds nutrients to the carbon found in peat moss. While other fertilizers spike soil with massive amounts of nutrients when wet, Carbon90PLUS naturally binds nitrogen, potassium, phosphate, sulfur and other micronutrients to carbon until plants need them.
BUILD YOUR SOIL - The secret behind Carbon90Plus lies in our use of carbon. Homogenous, granular prills, each containing a precise mix of nitrogen, phosphorous, potassium, calcium, sulfur, and micronutrients, break up evenly in your soil. Bound by carbon molecules, these nutrients provide a longer lasting, natural fertilizer which doesn’t leach with simple watering, unlike other fertilizers.
WATER SMART - Carbon90Plus is uniquely beneficial in both wet and dry climates, helping reduce the amount of water lost through irrigation.
