Temperature dependence of soil respiration

Temperature dependence of soil respiration after Equation 11 in Lloyd & Taylor (1994)

fLloydTaylor(RRef = R_ref.n, E0 = E_0.n, 
    TSoil = Tsoil.n, TRef = if (missing(T_ref.n)) 273.15 + 
        10 else T_ref.n, T0 = if (missing(T_0.n)) 227.13 else T_0.n, 
    R_ref.n, E_0.n, Tsoil.n, T_ref.n, T_0.n)

Arguments

RRef

Respiration rate at reference temperature

E0

TSoil

Soil temperature in Kelvin (degK)

TRef

Reference temperature of 10 degC in Kelvin (degK)

T0

Regression temperature as fitted by LloydTaylor (1994) in Kelvin (degK)
