Calculates the internal nutrient quotient \(Q_{int}\) and its relative effect on growth rate \(Q_{lim}\) via:
$$\begin{array}[ccc]
Q_{int} &=& Q_{min} \left(1 + \frac{N_s}{N_f}\right) \\
Q_{lim} &=& \frac{Q_{int} - Q_{min}}{Q_{int} - K_c}
\end{array}$$
Usage
Q_lim(Nf, Ns, spec_params)
Arguments
- Nf
Fixed nitrogen (mg m\(^{-3}\))
- Ns
Stored nitrogen (mg m\(^{-3}\))
- spec_params
a vector of named numbers. Must include:
Q_min, the minimum nutrient quotient
Q_max, the maximum nutrient quotient
K_c, the half-saturation growth constant
Value
a scalar of relative limitation from internal nutrient reserves on growth (between 0 and 1)
