Effects of moisture on decomposition rates according to the StandCarb model

Description

Calculates the effects of moisture on decomposition rates according to the StandCarb model.

Usage

fW.Standcarb(
  Moist,
  MatricShape = 5,
  MatricLag = 0,
  MoistMin = 30,
  MoistMax = 350,
  DiffuseShape = 15,
  DiffuseLag = 4
)

Arguments

`Moist`	A scalar or vector containing values of moisture content of a litter or soil pool (%).
`MatricShape`	A scalar that determines when matric limit is reduced to the point that decay can begin to occur.
`MatricLag`	A scalar used to offset the curve to the left or right.
`MoistMin`	A scalar determining the minimum moisture content.
`MoistMax`	A scalar determining the maximum moisture content without diffusion limitations.
`DiffuseShape`	A scalar that determines the range of moisture contents where diffusion is not limiting.
`DiffuseLag`	A scalar used to shift the point when moisture begins to limit diffusion.

Value

A data frame with limitation due to water potential (MatricLimit), limitation due to oxygen diffusion (DiffuseLimit), and the overall limitation of moisture on decomposition rates (MoistDecayIndex).
