Root depth growth calculation (only root depth, no root biomass)

LintulRoot.java The SimComponent LintulRoot.java calculates the daily increase in root depth (RROOTD in m d-1) depending on the crop development stage (DevStage) and the actual volumetric soil water content (WC). Vertical root growth only occurs when (1) the development of the crop has not reached anthesis (DevStage <span class="invalid-tag">Ungültige Eingabe: "<"</span>1) and (2) the actual rooting depth (ROOTD in m) is below the user defined maximum rooting depth (ROOTDM in m). In this case, daily root growth rate depends on the crop specific maximum daily root growth rate (RRDMAX in m d-1) and the volumetric soil water content (WC in m^3 m^-3) in relation to the volumetric soil water content at wilting point (WCWP in m^3 m^-3):

\[ \begin{eqnarray} if Ungültige Eingabe: "&" Ungültige Eingabe: "&" ROOTD > ROOTDM Ungültige Eingabe: "&" Ungültige Eingabe: "&" and Ungültige Eingabe: "&" Ungültige Eingabe: "&" DevStage Ungültige Eingabe: "<" 1: RROOTD = RRDMAX \cdot INSW(WC-WCWP) \end{eqnarray} \]

If crop developemnt has passed beyond anthesis or if ROOTD has reached ROOTDM, the daily increase in rrot depth is zero.
