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

A. $${\text{ANR}} = \left( {\frac{{{\text{Nutrient removed from fertilized plot}} - {\text{Nutrient removed from unfertilized plot}}}}{{{\text{Nutrient added}}}}} \right) \times 100$$

B. $${\text{ANR}} = \left( {\frac{{{\text{Nutrient removed from unfertilized plot}} - {\text{Nutrient removed from fertilized plot}}}}{{{\text{Nutrient added}}}}} \right) \times 100$$

C. $${\text{ANR}} = \left( {\frac{{{\text{Nutrient removed from unfertilized plot}} - {\text{Nutrient removed from fertilized plot}}}}{{{\text{Nutrient removed from unfertilized plot}}}}} \right) \times 100$$

D. None of these

Answer: Option A

Solution(By Examveda Team)

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.
