What is the term for the statement on a fertilizer bag that lists percentages of nitrogen, phosphorous, and potassium?

The term for the statement on a fertilizer bag that lists the percentages of nitrogen, phosphorus, and potassium is known as fertilizer analysis. This analysis provides crucial information regarding the nutrient composition of the fertilizer, which is essential for determining its suitability for various plants or soil types.

Fertilizer analysis typically follows a specific format, usually represented as a series of three numbers, such as 10-20-10. Each of these numbers represents the percentage of the three primary nutrients: nitrogen (N), phosphorus (P), and potassium (K). This information helps gardeners, farmers, and landscapers make informed decisions about their fertilizer choices, ensuring that they provide the correct nutrients to support plant growth.

The other options pertain to different concepts. Chelated-release analysis typically relates to how nutrients are made available in a slow-release form, which isn't a standard term used on fertilizer bags. Micro-element analysis would focus on trace minerals, rather than the primary nutrients. Essential element analysis could suggest a broader range of nutrients but isn't the specific term used for the key nutrient percentages listed on a fertilizer bag.
