Occasionally, fertilizer recommendations given as lb nitrogen per 1000 sq ft must be converted to lb fertilizer per acre. How many 50-lb bags of 26-5-10 will you need to fertilize a 30,000 sq ft lawn at 1.0 lb nitrogen per 1000 sq ft? If a 50-lb bag of 26-5-10 fertilizer covers 13,200 sq ft at 1.0 lb nitrogen per 1000 sq ft, determine how many times 13,200 goes into 30,000.ģ0,000 sq ft ÷ 13,200 sq ft = 2.3 bags of 26-5-10 will cover 30,000 sq ft. Thus, a 50-lb bag of 26-5-10 covers 13,200 sq ft at a rate of 1.0 lb nitrogen per 1000 sq ft. How much area can be covered with a 50-lb bag of 26-5-10 at the rate of 1.0 lb nitrogen per 1000 sq ft? Now that you know 3.8 lb of 26-5-10 fertilizer will cover 1000 sq ft, determine how many times 3.8 lb goes into 50 lb: 50 lb ÷ 3.8 lb = 13.2 (3.8 lb fertilizer per 1000 sq ft) x 0.10 potash = 0.38 lb potash per 1000 sq ftĪnother common problem involves determining the area that a bag of fertilizer can cover and how many bags are needed to cover large sites. (3.8 lb fertilizer per 1000 sq ft) x 0.05 phosphate = 0.19 lb phosphate per 1000 sq ft Remember to convert the percentages of phosphate and potash to their decimal forms. Multiply the amount of fertilizer you are applying (3.8 lb per 1000 sq ft) by the percentage of phosphate in the bag (5%). Exampleįind out how much phosphate and potash you are applying to the turf when you apply the 3.8 lb of the 26-5-10 fertilizer per 1000 sq ft from the previous example. (1.0 lb nitrogen per 1000 sq ft) ÷ 0.26 = 3.8 lb of a 26-5-10 fertilizer is needed to supply 1.0 lb nitrogen per 1000 sq ft. When using percentages in calculations, convert the number to its decimal form (for example, 26% = 0.26 5% = 0.05). The quickest way to solve this problem is to ignore the weight of the fertilizer bag and simply divide the amount of nitrogen desired (1.0 lb nitrogen per 1000 sq ft) by the percentage of nitrogen in the bag (26%). How much of the 26-5-10 fertilizer will you need to apply per 1000 sq ft? You have a 50-lb bag of 26-5-10 fertilizer that you want to apply to a lawn at a rate of 1.0 lb nitrogen per 1000 sq ft.
