Calculate aggregate stability index based on occupation CEC

Source: R/cec.R

This function calculates an aggregate stability index given the CEC and its occupation with major cations.

calc_aggregatestability(
  B_SOILTYPE_AGR,
  A_SOM_LOI,
  A_K_CO_PO,
  A_CA_CO_PO,
  A_MG_CO_PO
)

Arguments

B_SOILTYPE_AGR

(character) The type of soil

A_SOM_LOI

(numeric) The organic matter content of soil in percentage

A_K_CO_PO

(numeric) The occupation of the CEC with K (%)

A_CA_CO_PO

(numeric) The occupation of the CEC with Ca (%)

A_MG_CO_PO

(numeric) The occupation of the CEC with Mg (%)

Value

The aggregate stability index of a soil given the Cation Exchange Capacity and its composition with major cations. A numeric value.

Examples
