Compute soil K availability terms for the K balance

Compute soil K availability terms for the K balance

Usage

soil_K_availability(
  k_value,
  unit = c("K", "K2O"),
  soil_group,
  A_demand_K2O,
  clay_pct,
  include_leaching = TRUE,
  k_availability.table = NFert::k_availability.table
)

Arguments

k_value, unit, soil_group

K analytical value and DPI texture group.

A_demand_K2O

Crop K2O demand (kg/ha) from calc_crop_K_demand().

clay_pct

Clay percentage, used to compute leaching H.

include_leaching

Logical, add K leaching to mantenimento term. Default TRUE.

k_availability.table

Lookup table.

Value

A list with strategy, ID_Gri_K, B1, A_mantenimento (asportazione + H), B2, H (leaching).

Examples

soil_K_availability(k_value = 150, unit = "K2O",
                    soil_group = "Medio impasto",
                    A_demand_K2O = 119.4, clay_pct = 18.5)
