NUEFC {NUETON}

Calculate NUE of a Food Chain (NUEFC)

Description

The N balance of the entire food chain system, in terms of N consumed as protein relative to N inputs. Calculate NUEFC using the formula: NUEFC = Ncon / Ni

Usage

NUEFC(Ncon, Ni)

Arguments

Ncon

The value of N available for consumption

Ni

Sum total of new N input

Value

The calculated NUEFC value.
