Direct Known Subclasses:: LintulCassavaFunctions

public class LintulFunctions extends Object

Implements functions for the model Lintul5. WIKI_START 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. == References == - (L5) [http://models.pps.wur.nl/content/lintul-5-crop-growth-simulation-model-potential-water-limited-n-limited-and-npk-limited-co-0 LINTUL-5 Crop growth simulation model for potential, water-limited, N-limited and NPK-limited conditions] WIKI_END

  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
  
  Parameters:
  
  FixationRestrictionFactor -
  
  DVS - development stage
  
  RootDepth - root depth
  
  SoilLayerDepth - bottom depth of all soil layers
  
  FieldCapacity - field capacity per soil layers
  
  WaterContent - water content per soil layers
  
  NitrogenContent - nitrogen content per soil layers
