  • 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.
