74: Effects of temperature on decomposition rates according to a...

In SoilR: Models of Soil Organic Matter Decomposition

Description

Calculates the effects of temperature on decomposition rates according to the modified Van't Hoff function (Q10 function).

Usage

fT.Q10(Temp, k_ref = 1, T_ref = 10, Q10 = 2)

Arguments

Temp	A scalar or vector containing values of temperature for which the effects on decomposition rates are calculated.
k_ref	A scalar representing the value of the decomposition rate at a reference temperature vaule.
T_ref	A scalar representing the reference temperature.
Q10	A scalar. Temperature coefficient Q10.

Value

A scalar or a vector containing the effects of temperature on decomposition rates (unitless).
