Apparent Nutrient Recovery (ANR) Calculator
Definition:
Apparent Nutrient Recovery (ANR) is the proportion of applied nutrient that is taken up by the crop. It is calculated as the increase in nutrient uptake due to fertilizer application, expressed as a percentage of the nutrient applied.
Apparent Nutrient Recovery (ANR) is the proportion of applied nutrient that is taken up by the crop. It is calculated as the increase in nutrient uptake due to fertilizer application, expressed as a percentage of the nutrient applied.
Formula:
Apparent Nutrient Recovery (%) =
[(Uptake with fertilizer − Uptake without fertilizer) ÷ Nutrient applied] × 100
Apparent Nutrient Recovery (%) =
[(Uptake with fertilizer − Uptake without fertilizer) ÷ Nutrient applied] × 100
