)

Arguments

B_LU

(numeric) The crop code from the BRP

B_SOILTYPE_AGR

(character) The agricultural type of soil

A_SOM_LOI

(numeric) The percentage organic matter in the soil (%)

A_CLAY_MI

(numeric) The clay content of the soil (%)

A_PH_CC

(numeric) The acidity of the soil, measured in 0.01M CaCl2 (-)

A_CEC_CO

(numeric) The cation exchange capacity of the soil (mmol+ per kg), analyzed via Cobalt-hexamine extraction

A_K_CO_PO

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

A_MG_CC

(numeric) The plant available content of Mg in the soil (mg Mg per kg) extracted by 0.01M CaCl2

A_K_CC

(numeric) The plant available potassium, extracted with 0.01M CaCl2 (mg per kg),

unitcheck

(character) Option to switch off unit checks (TRUE or FALSE)

Value

An index representing the availability of Magnesium in a soil. A numeric value.
