Calculate the indicator for Potassium Availability

Source: R/potassium.R

This function calculates the indicator for the the Potassium Availability of the soil by using the K-availability calculated by calc_potassium_availability

ind_potassium(D_K, B_LU_BRP, B_SOILTYPE_AGR, A_SOM_LOI)

Arguments

D_K

(numeric) The value of K-index calculated by calc_potassium_availability

B_LU_BRP

(numeric) The crop code from the BRP

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_SOM_LOI

(numeric) The organic matter content of the soil (%)

Value

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

Examples

ind_potassium(D_K = 4.5,B_LU_BRP = 256,B_SOILTYPE_AGR='dekzand',A_SOM_LOI=4)
