carbon_stocks: Calculate soil carbon stocks

Description

Calculation of carbon stocks based on an object of class ‘soil_profile’

Usage

carbon_stocks(
  x,
  depth,
  area = c("m2", "ha"),
  method = c("linear", "constant"),
  ...
)

Value

returns a value with attribute ‘units’ and ‘depth’

Arguments

x

object of class ‘soil_profile’

depth

soil depth (in meters). If missing then the whole soil profile is used.

area

either ‘m2’ meter squared or ‘ha’.

method

interpolation method. Either ‘linear’ or ‘constant’.

...

additional arguments passed to internal functions (none used at the moment).

Details

Function to calculate carbon stocks. The output units depend on the choice of area. If ‘m2’ is used, then the output units will be ‘kg/m2’. If the ‘area’ is ‘ha’, then the output units will be ‘Mg/ha’.

Note that the bulk density (which is needed in the calculation) is available as part of the ‘soil_profile’ object.

Examples

if (FALSE) {
sp <- apsimx_soil_profile()
carbon_stocks(sp)
carbon_stocks(sp, depth = 0.1)
carbon_stocks(sp, depth = 0.2)
carbon_stocks(sp, depth = 0.3)
carbon_stocks(sp, depth = 0.4)
}
