NdfF: Calculate N derived from Fertilizer (NdfF)

In NUETON: Nitrogen Use Efficiency Toolkit on Numerics

Calculate N derived from Fertilizer (NdfF)

Description

The percentage of plant or soil N that is derived from the fertilizer. Calculate NdfF using the formula: NdfF = Plant15N/Fert15N

Usage

NdfF(Plant15N, Fert15N)

Arguments

Plant15N	A vector of 15N atom percent excess in plant or soil values.
Fert15N	15N atom percent excess of fertilizer N.

Value

The calculated NdfF value expressed as a percentage.
