  • What is the ratio of nitrogen to phosphate in fertilizer?

  • To determine a fertilizer ratio for a recommendation of 1.5 lb of nitrogen, 0.5 lb of phosphate, and 0.5 lb of potash, divide the weight of each of the three nutrients (1.5 lb, 0.5 lb, 0.5 lb) by the nutrient with the lowest weight (0.5 lb).

  • What is the best fertilizer ratio for your lawn?

  • Thus, the fertilizer ratio that best fits this recommendation is 3-1-1. You can also determine fertilizer ratios from fertilizer grades by dividing the percentage of nitrogen, phosphate, and potash by the lowest percentage of the three nutrients. Determine ratios for the following fertilizer grades: 21-7-7. 22-6-8, and 18-5-9.

  • How to calculate the phosphorus application rate?

  • Calculating the phosphorus application rate: For liquid fertilizers, the weight of the fertilizer must be accounted for, because the fertilizer nutrient content is given as percentage by weight. For example, Urea Ammonium Nitrate (UAN), a liquid fertilizer with a grade of 30-0-0 contains 30% nitrogen by weight.
