what does fertilizer analysis mean

Best answer

Fertilizer analysis refers to afertilizer’s formulation of the three macronutrients: nitrogen (N),phosphorus (P),and potassium (K). It is commonly referenced as N-P-K. Most bags of fertilizers feature an N-P-K fertilizer analysis of 5-10-5 or 18-9-9.

  • What is a guaranteed analysis of fertilizer?

  • The guaranteed analysis(or fertilizer grade) is a listing of nutrients contained in the bag, by weight. The first number of the analysis lists % N, the second number represents % P2O5 (phosphate), and the third number % K2O (potash). The guaranteed analysis of the fertilizer in the above example is: 18-6-12.

  • What is a fertilizer?

  • A fertilizer is a natural or synthetic, chemical-based substance that is used to enhance plant growth and fertility. Fertilizers may also enhance water retention and filter any excess liquid, hence enhancing soil effectiveness. Fertilizers typically offer the three major macronutrients potassium, phosphorus, and nitrogen.

  • What do the numbers on fertilizer mean?

  • These numbers represent nitrogen, phosphorus and potassium content. Some fertilizers have more than three numbers, and in those cases the extra numbers represent other nutrients. It doesn鈥檛 matter if it is liquid or dry fertilizer, as the numbers represent the percent by weight of each nutrient the product contains.

  • How do you calculate fertilizer analysis for a blend?

  • If you have a blend of equal amounts of 18-46-0 and 0-0-60, then the resulting blend would have an analysis of 9-23-30. You just take the proportion of each times the analysis and add together. Since the blend is half of each fertilizer product, the new analysis is 0.5 times the analysis numbers.
