Detailed explanation-1: -Prominently featured, the N-P-K-ratio is the percentage the product contains by volume of nitrogen (chemical symbol N), phosphorus (P), and potassium (K). A 16-16-16 fertilizer, for example, contains 16% nitrogen, 16% phosphorus, and 16% potassium.
Detailed explanation-2: -Studies have found that the ideal NPK fertilizer ratio of those nutrients for flowering plants is 3-1-2. (That’s 3% Nitrogen, 1% phosphorus & 2% potassium.) So look for that ratio on the label of packaged fertilizers; anything close to a 3-1-2, a 6-2-4 or a 9-3-6 should be ideal.
Detailed explanation-3: -Every label carries three conspicuous numbers, usually right above or below the product name. These three numbers form what is called the fertilizer’s N-P-K ratio-the proportion of three plant nutrients in order: nitrogen (N), phosphorus (P) and potassium (K).
