The symbols of these nutrients, respectively, are N – P – K numbers fertilizer packages represent the proportion of nutrients to the total weight of the package. 50 pounds so a bag labeled 25-5-10 is 25% nitrogen, phosphorus, 5%, 10% potassium. Multiplying the weight of the package, with the percentage of nutrients can determine the number of pounds each nutrient. Thus in the example above, .25 * 50 pounds = 12.5 kg. nitrogen, 2.5 pounds. phosphorus and 5 pounds. potassium.So what the rest of the bag contain? Usually fillers.
