Apparent nutrient recovery (ANR) can't calculated by using of which formula

Apparent Nutrient Recovery is one of the more complex forms of NUE expressions and is defined as the difference in nutrient uptake in above-ground parts of the plants between the fertilized and unfertilized crop relative to the quantity of nutrient applied.
This can be calculated if you have values of Nutrients removed from the fertilized plot, nutrients removed from the unfertilized plot, and nutrients added.
