What does a fertilizer analysis percentage listed on a container represent?

Complete Fertilizer
Fertilizer Analysis
Urea-formaldehyde
Susceptible/Pest Resistant

The correct answer is: Fertilizer Analysis

A complete fertilizer is a type of fertilizer that contains all three main nutrients required for plant growth (nitrogen, phosphorus, and potassium), as well as additional minor nutrients. It does not refer to a percentage listed on a container. Urea-formaldehyde is a type of slowly releasing organic fertilizer and does not refer to a percentage listed on a container. Susceptible/Pest Resistant does not refer to a percentage listed on a container. It might be related to whether or not the fertilizer is effective in controlling pests or making plants more resistant to pests, but it is not directly related to the fertilizer analysis percentage.
