For Homeowners: One 45-lb. bag will cover 3,000 square feet. At this rate, 0.75 lbs. of nitrogen per 1,000 sq. ft. will be applied. OCEANGRO® should be applied at rates no greater than the nitrogen requirement of the plant. for application rates. For additional literature regarding proper fertilization, calibration of lawn fertilizer spreaders, etc. <Click Here>. For Golf Courses and Athletic Fields: Maintenance rates start at 1/2 ton per acre - this will provide 1.1# nitrogen total and 0.12# nitrogen available. A 1-ton to the acre rate is recommended for first time use, if in areas of sandy soil or if soils are nutrient poor. Keep in mind the slow-release properties of OCEANGRO®. Low initial rates of OCEANGRO® may not give you the plant response you may be used to seeing in synthetic chemical fertilizers. It is better to initially start at a higher OCEANGRO® rate to build up a slow-release residual then adjust subsequent application rates lower as necessary to match the needs of the plants you are growing.
