\begin{equation}
SAPL_{leaf}
\begin{cases}
\dfrac{0.1}{SLA} & \\
\dfrac{1}{SLA} & \text{if PFT crop}
\end{cases} %\]
\end{equation}

\begin{equation}
SAPL_{sapabove} = 0
\end{equation}

\begin{equation}
SAPL_{sapbelow} = 0
\end{equation}


\begin{equation}
SAPL_{heartabove} = 0
\end{equation}

\begin{equation}
SAPL_{heartbelow} = 0
\end{equation}

\begin{equation}
SAPL_{root} = 0.1 \cdot \frac{1}{\alpha_{grass}} \cdot SAPL_{leaf} 
\end{equation}

\begin{equation}
SAPL_{fruit} = 0.3 \cdot SAPL_{leaf} 
\end{equation}

\begin{equation}
SAPL_{reserve} = 5 \cdot SAPL_{leaf}
