An arrhythmia is any disorder of your heart rate or rhythm. It means that your heart beats too quickly, too slowly, or with an irregular pattern. Most arrhythmias result from problems in the electrical system of the heart. If your arrhythmia is serious, you may need a cardiac pacemaker or an implantable cardioverter defibrillator (ICD). They are devices that are implanted in your chest or abdomen. A pacemaker helps control abnormal heart rhythms.
Generally speaking, the numbers refer to the parentages of Nitrogen, Phosphorus and Potassium, by weight, listed in this exact order and contained in the fertilizer. These numbers stand for the percentages contained within a specific package.
Bags of 13-13-13 fertilizer contain dry particles that must be watered after application to release the nutrients. To find the amount of each nutrient in a 40-lb. bag, multiply 0.13 by 40. In this formulation, 5.2 pounds each of nitrogen, phosphorus and potassium are available, for a total of 15.6 pounds.hese three numbers represent the content of primary nutrients in the fertilizer formulation: nitrogen, phosphorus and potassium. By looking at the numbers on a fertilizer bag, homeowners can calculate how many pounds of each nutrient are contained within the bag.
