| fW.RothC {SoilR} | R Documentation |
Calculates the effects of moisture (precipitation and pan evaporation) on decomposition rates according to the RothC model.
fW.RothC(P, E, S.Thick = 23, pClay = 23.4, pE = 0.75, bare = FALSE)
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. |
A data.frame with accumulated top soil moisture deficit (Acc.TSMD) and the rate modifying factor b.
