NRE15 {NUETON}

Calculate Isotope-Based Recovery Efficiency of N-Fertlizer (NRE15)

Description

The percent recovery, or utilization, of fertilizer-N in plant and/or soil components Calculate NRE15 using the formula: NRE15 = (TNdfF in Plant or Soil / FertN) * 100

Usage

NRE15(TNdfF, FertN)

Arguments

TNdfF

Total N derived from Fertilizer in plant or soil value.

FertN

A numeric value for fertilizer N input.

Value

The calculated NRE15 value as a percentage.
