The application will control all broadleaf weeds and crabgrass without damaging or yellowing turf. C. Round 3 Granular Fertilizer with 1% Fe (County sites only; no athletic fields). Application will begin April 15 and be completed by May 15. The fertilizer must contain iron and be applied at a rate of 1 lb. of at least 50% slow release nitrogen per 1,000 sq. ft. and the fertilizer ratio will be 10:1:3 or approximate equivalent. D.
