NPK Labelling of FertilizersChart for fertilizer that shows N for nitrogen, P for phosphorous and K for potassium and it says green foliage, strong roots and healthy growth

The numbers on the bag associated with each letter are the percentages of that element. For example, 16-4-8 is 16% nitrogen, 4% phosphorus, and 8% potassium.
