This Pro-Pell-It! 34872 8-0-4 is a mini granular turf blend formulated to achieve an optimal distribution while spreading, and provide sustained feeding throughout the season. Derived from feather meal, sulfate of potash magnesia, iron sucrate, and olivine, this blend is recommended for turf applications at 5-15 lbs. per 1000 square feet up to 4 times per year. The feather meal provides a slow release source of nitrogen for steady feeding while the olivine and iron sucrate provide nutrients needed for a deep, green color.
