What is the difference between a complete and an incomplete fertilizer?
John Wick
Completed has all three primary nutrients-nitrogen phosphorous & potassium
Incomplete does not have all three primary nutrients
Andrew Pel
A complete fertilizer has all three of the major elements present. An example of a complete fertilizer is the 16-4- 8 mentioned above because it contains percentages of nitrogen, phosphorus, and potassium. An incomplete fertilizer contains only one or two of the major elements.

Complete fertilizers include all three primary nutrients (nitrogen, phosphorus, and potassium); incomplete fertilizers contain only one or two. Complete fertilizers are usually in the form of pellets or granules for easy spreading.

A fertilizer is said to be a complete or mixed fertilizer when it contains nitrogen, phosphorus and potassium (the primary nutrients). Examples of commonly used complete fertilizers are 6-12-12, 10-10-10, 15-15-15 and 20-10-10. An incomplete fertilizer will be missing one or more of the major components. Examples of incomplete fertilizers are: 34-0-0 (ammonium nitrate), 46-0-0 (urea), 18-46-0 (diammonium phosphate), 0-46-0 (triple super phosphate) and 0-0-60 (muricate of potash).
Incomplete fertilizers are blended to make complete fertilizers. As an example, if 100 pounds of 46-0-0 (urea) were combined with 100 pounds of 0-46-0 (concentrated super phosphate) and 100 pounds of 0-0-60 (muricate of potash), a fertilizer grade of 15-15-20 would result. When these quantities are combined, each quantity is diluted by the other two materials by one-third, provided each fertilizer material contributed equal weight to the blend.
