The total percentage of nutrients in a 20-10-20 fertilizer (N+P+K) is?

Explanation:
Nutrient analysis on fertilizer bags is shown as three numbers representing the percentages by weight of nitrogen (N), phosphate (as P2O5), and potash (as K2O). For a 20-10-20 fertilizer, you simply add the three values: 20 + 10 + 20 = 50. This means half of the bag’s weight is the primary plant nutrients, while the other half is filler, carrier, moisture, or inert material. Micronutrients, if present, are listed separately and aren’t included in this total. So the total percentage of major nutrients is 50%.
