Calculate the Zn availability index for agricultural soils in Romenia

This function calculates the Zn availability of a soil, using the agronomic index used in RO.

Usage

osi_c_zinc_ro(B_LU, A_PH_WA, A_P_AL, A_ZN_EDTA, unitcheck = TRUE)

Arguments

B_LU

(character) crop type

A_PH_WA

(numeric) pH measured in water (-)

A_P_AL

(numeric) The P-content of the soil extracted with ammonium lactate (mg P / kg)

A_ZN_EDTA

(numeric) Zn content measured in EDTA, pH 8.6, with ammonium carbonate (mg / kg)

unitcheck

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

Value

The zinc availability index in United Kingdom estimated from extractable zinc and pH measured in water, a numeric value.

Examples

osi_c_zinc_ro(B_LU = 'testcrop', A_ZN_EDTA = 45, A_P_AL = 45,A_PH_WA = 6.5)
