In SoilR: Models of Soil Organic Matter Decomposition

Effects of moisture on decomposition rates according to the DAYCENT model

Description

Calculates the effects of Soil Water Content on decomposition rates according to the Daycent Model.

Usage

fW.Daycent1(
  swc,
  a = 0.6,
  b = 1.27,
  c = 0.0012,
  d = 2.84,
  partd = 2.65,
  bulkd = 1,
  width = 1
)

Arguments

swc	A scalar or vector with soil water content of a soil layer (cm).
a	Empirical coefficient. For fine textured soils a = 0.6. For coarse textured soils a = 0.55.
b	Empirical coefficient. For fine textured soils b = 1.27. For coarse textured soils b = 1.70.
c	Empirical coefficient. For fine textured soils c = 0.0012. For coarse textured soils c = -0.007.
d	Empirical coefficient. For fine textured soils d = 2.84. For coarse textured soils d = 3.22.
partd	Particle density of soil layer.
bulkd	Bulk density of soil layer (g/cm^3).
width	Thickness of a soil layer (cm).

Value

A data frame with values of water filled pore space (wfps) and effects of soil water content on decomposition rates. Both vectors are unitless.
