How much phosphorus and potassium should I look for in a fertilizer? Many Florida soils are naturally high in phosphorus, so you should use a soil test to determine if you even need to apply this nutrient. Contact your county's UF/IFAS Extension office to get a soil test form and learn how to take one. If you have ample phosphorus in your soil, look for a fertilizer with no more than 2% phosphorus. As for potassium, look for a fertilizer with at least half as much potassium as nitrogen (16-2-8) or equal amounts of nitrogen and potassium (15-0-15), depending on the results of your soil test. How much fertilizer should I apply to a lawn? How much to apply depends on three things: 1. Your desired level of maintenance 2. The amount of nitrogen in the bag 3. What percentage of that nitrogen is slow-release FYN generally recommends applying the lowest end of the fertilizer ranges recommended by the UF Turfgrass Science program (low maintenance level). Understand that at times an underfertilized lawn may be less pest- or diseaseresistant and unable to perform as well in preventing erosion. On the other hand, lawns receiving more fertilizer than recommended by FYN guidelines generally require more mowing, additional irrigation and may develop more pest problems. Regardless of the level of maintenance you desire, adhere to the following guidelines. ■ ■ If you are applying a fertilizer with less than 30% of its nitrogen in a slowrelease form, only apply ½ pound of nitrogen per 1,000 square feet of lawn per application. If it has at least 30% slow-release nitrogen, you may apply up to 1 pound of nitrogen per 1,000 square feet of lawn per application. For more help calculating the amount of fertilizer to apply to your lawn, see Tables 2 and 3 (pages 53 and 54). Regardless of the total nitrogen applied over a year, even at high maintenance levels, it is the amount of nitrogen applied at any one time and the proper application and watering-in that has the greatest impact on the potential for creating pollution. Figuring Out Fertilizer for the Home Lawn: 52
How should I apply fertilizer to a lawn? Follow these simple steps: 1. Determine the annual fertility needs of your grass species by referring to Table 2 below. 2. Measure the square footage of your lawn area. Do not include landscape plants in this area calculation. 3. Determine how much slow-release nitrogen is in your fertilizer. Table 2. Fertilization Guidelines for Established Turfgrass Lawns in Three Regions of Florida Nitrogen recommendations (lbs N/1000 ft 2 /year) * Species North Central South Bahiagrass 2-3 2-4 2-4 Bermudagrass 3-5 4-6 5-7 Centipedegrass 1-2 2-3 2-3 St. Augustinegrass 2-4 2-5 4-6 Zoysiagrass 3-5 3-6 4-6 * Homeowner preferences for lawn quality and maintenance will vary, so the UF Turfgrass Science program recommends a range of fertility rates for each grass species and location. Also, effects within a localized region (for instance, shade, drought, soil conditions and irrigation) will require using a range of fertility rates. FYN generally recommends applying no more than the lowest of the recommended fertilizer ranges. These recommendations assume that grass clippings are recycled. http://edis.ifas.ufl.edu/EP221 53
