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

Description Usage Arguments Value Author(s) Examples

Description

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

Usage

1
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).
