net.simplace.sim.components.models.lintul5.LintulFunctions

Implements functions for the model Lintul5.

Algorithms are the same as in (L5). There are only technical changes due to translation from Fortran to JAVA and integration into Simplace Framework.

Functions are called by the SimComponent Lintul5.

This subroutine calculates atmospheric transmission, potential evaporation from a free water surface (E0), a bare soil surface (ES0) and the potential transpiration of a closed crop canopy (ET0); CO2 effect on crop transpiration is included. Author : Daniel van Kraalingen, based on an earlier version written by: Kees van Diepen and Gert-Jan Nooy
returns
public static double SWEAF(double ET0, double CGNR);

Calculates the fraction of easily available soil water between fc and wp Chapter 20 in documentation WOFOST Version 4.1 (1988) The fraction of easily available soil water between field capacity and wilting point is a function of the potential evapotranspiration rate (for a closed canopy) in cm/day, ET0, and the crop group number, CGNR (from 1 (=drought-sensitive) to 5 (=drought-resistent)). The function SWEAF describes this relationship given in tabular form by Doorenbos & Kassam (1979) and by Van Keulen & Wolf (1986; p.108, table 20). Authors: D.M. Jansen and C.A. van Diepen, October 1986.
returns the fraction of easily available soil water between fc and wp
public static double calculateNFixationFraction(double
FixationRestrictionFactor, double DVS, double RootDepth, Double[]
SoilLayerDepth, Double[] FieldCapacity, Double[] WiltingPoint, Double[]
WaterContent, Double[] NitrogenContent);

Calculate the fraction of N demand that is fullfilled by N fixation The fraction depends on development, soil water content in the upper 30cm and total N content in the rooted zone. The FixationRestrictionFactor controls how much these conditions influence the fraction. See: Williams and Izaurralde, The Apex Model, Equation 288 and 288a-288i
