ind_nretention {OBIC}

Calculate the indicator for N retention for groundwater or surface water

Description

This function calculates the indicator for the N retention of the soil by using the N leaching to groundwater or surface water calculated by calc_nleach

Usage

ind_nretention(D_NW, leaching_to)

Arguments

D_NW

(numeric) The value of N leaching calculated by calc_nleach

leaching_to

(character) whether it evaluates N leaching to groundwater ("gw") or to surface water ("ow")

Value

The evaluated score for the soil function to supply nitrogen for crop uptake. A numeric value between 0 and 1.

Examples

ind_nretention(D_NW = 15,leaching_to = 'gw')
ind_nretention(D_NW = c(.2,5.6,15.6),leaching_to = 'ow')
