N P K

NPK on a fertilizer package stands for nitrogen, phosphorus, and potassium the three nutrients that compose complete fertilizers. While the description of the fertilizer may not expressly say “NPK” you will see a series of three numbers, often separated by dashes. These numbers correspond, respectively, to the percentage of nitrogen, phosphorus, and potassium in that fertilizer.For example, if you purchase a 10-pound bag fertilizer labeled  it contains 5 percent nitrogen, 10 percent phosphorus, and 5 percent potassium by weight. The remaining 80 percent of the bag’s weight is comprised of minor nutrients or fillers.
