fW.RothC R Documentation
Effects of moisture on decomposition rates according to the RothC model
Description
Calculates the effects of moisture (precipitation and pan evaporation) on
decomposition rates according to the RothC model.
Usage
fW.RothC(P, E, S.Thick = 23, pClay = 23.4, pE = 0.75, bare = FALSE)
Arguments
P
A vector with monthly precipitation (mm).
E
A vector with same length with open pan evaporation or
evapotranspiration (mm).
S.Thick
Soil thickness in cm. Default for Rothamsted is 23 cm.
pClay
Percent clay.
pE
Evaporation coefficient. If open pan evaporation is used pE=0.75.
If Potential evaporation is used, pE=1.0.
bare
Logical. Under bare soil conditions, bare=TRUE. Default is set
under vegetated soil.
Value
A data.frame with accumulated top soil moisture deficit (Acc.TSMD)
and the rate modifying factor b.
