In order to figure out how many pounds of each nutrient are in this fertilizer you would do the following math.
Ex. N-P-K 7-22-5Total Mix= 2000 lbs.
Total N = 140 lbs.
Total P = 440 lbs.
Total K = 100 lbs.

Fertilizer Ratios N-P-K
The farm can't supply all of the nutrients that are needed for their crops with just manure. They use commercial fertilizer to provide the remaining nutrients needed. Fertilizer values come in the form of a ratio. Each number in the ratio is a percentage of that nutrient, based on the total weight of the fertilizer mix. The three major nutrients in all fertilizers are Nitrogen, Phosphorus and Potassium. A typical fertilizer mix that is commonly used has a ratio of 7-22-5.
In order to figure out how many pounds of each nutrient are in this fertilizer you would do the following math.
Ex. N-P-K 7-22-5
Total Mix= 2000 lbs.
Total N = 140 lbs.
Total P = 440 lbs.
Total K = 100 lbs.
