calc_aggregatestability {OBIC} | R Documentation |
Calculate aggregate stability index based on occupation CEC
Description
This function calculates an aggregate stability index given the CEC and its occupation with major cations.
Usage
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
calc_aggregatestability(B_SOILTYPE_AGR = 'dekzand', A_SOM_LOI = 3.5,
A_K_CO_PO = 6,A_CA_CO_PO = 83 ,A_MG_CO_PO = 9)
calc_aggregatestability(B_SOILTYPE_AGR = c('dekzand','rivierklei'), A_SOM_LOI = c(3.5,6.5),
A_K_CO_PO = c(6,9),A_CA_CO_PO = c(83,75) ,A_MG_CO_PO = c(9,4))
