net.simplace.sim.components.management.SimpleFertilizer

Applies fertilizer by using tabular values - designed to use Lintul5-style fertilizer tables

Fertilizer has to be provided as an array, where the entries containing DOY of fertilization alternate with entries containing corresponding fertilizer amount: .

E. g.:

DOY	50	180	320
Amount	130.5	120	127.3

has to be provided as array

130.5

180

120

320

127.3

This is the way interpolation tables are handled in FST (see also FSTFunctions). Lintul5 uses this mechanism for fertilization.

There are three tables the user can provide: cNitrateTAB, cAmmoniaTAB, cPotassiumTAB, cPhosphorusTAB and cNitrateAndAmmoniaTAB .

Each of the table populates the corresponding output Nitrate, Ammonia, Potassium, Phosphorus or NitrateAndAmmonia.

Notice: Nitrate and Ammonia do not add to NitrateAndAmmonia. This output is related only to cNitrateAndAmmoniaTAB!
