Continued ... The two other nutrients found in lawn fertilizers, having much smaller ratios, are Sulfur (S) and Iron (Fe). Sulfur helps maintain a dark green color, while encouraging vigorous growth. Since we want a lawn to grow at an even, gradual pace, it is important that this number be very low in proportion to the other nutrients. And of course, every lawn needs Iron to maintain a dark green leaf. This is added to fertilizers because poor soil lacks it. Be careful with iron-enriched fertilizers, though. If it is not a non-staining iron, you will see rust spots on any hard surface your fertilizer may come in contact with.
Now let’s discuss the different amounts or percentages of these nutrients in lawn fertilizers. These are percentage by weight and are indicated on the label as a hyphenated number. They are always listed alphabetically. For example, a label that reads 21-7-14 has a higher percentage of Nitrogen than Phosphorus or Potassium, with Potassium being the next highest amount. A fertilizer that reads 15-15-15 has equal amounts of all three. The percentages and ratios can get a little confusing, but remembering that the larger the number, the large amount of that nutrient in that particular fertilizer is really the important thing. Then you need to know what nutrient your lawn needs and when.
