write_xdb_mFertilize: Write SALUS xdb.xml Fertlizer Management for Rotation...

In jdeines/salustools: Tools to Work with the SALUS Crop Model

Description

This function writes the fertilizer management arguments after write_xdb_rotation has been run. See http://salusmodel.glg.msu.edu/salus.ddb.xml for more information about SALUS parameter options. This function should be followed with additional write_xdb_m* (rotation managements), and write_xdb_bottomMatter functions to complete the Experiment file. Includes an option to close the rotation compoment if this is the last management specified.

Usage

write_xdb_mFertilize(outFile, Year, DOY, ANfer, closeComponent = "N")

Arguments

outFile	Full file path for an existing .xdb.xml to appended to, created with write_xdb_topMatter
Year	Year of fertilization event - if needed (fertilizing on Reported date); XXXX
DOY	day of year of fertilization event; only needed if fert management is 'R' or 'Y'. Valid range: 1-366
ANfer	amount of nitrogen in fertilizer <- 78.47 # kg / ha
closeComponent	'Y' or 'N' . Should the rotation component be closed? defaults to 'N'

Details

All other SALUS fertilizer parameters are set currently as default.

Examples

# file path to existing .xdb.xml file created by write_xdb_topMatter
fileOut <- 'C:/Users/deinesji/1PhdJill/test.xdb.xml'

# append rotation component parameters to .xdb.xml; numeric parameters can be character or numeric
write_xdb_mFertilize(outFile = fileOut, Year = 2007, DOY = 75, ANfer = 78.47)
