extends net.simplace.sim.model.FWSimComponent

Calculates potential denitrification rate from soil organic carbon content

Calculation

Potential denitrification rate is calculated from interpolation table defined by cDenitrificationTableOrganicCarbon and cDenitrificationTablePotentialRate.

When using the default values , the potential rate increases linearly from 1 mg/(kg d) at 1% organic carbon to 20 mg/(kg d) at 6% organic carbon.

The potential nitrification rate is calculated for each layer up to the cDenitrificationSoilDepth, converted to g / (m^2 d) by multiplying with layer thickness and bulk density of layer and then summed up. The final output is the PotentialDenitrificationRate in g / (m^2 d).

Usage

The output PotentialDenitrificationRate can be linked to the SimCoponents NPKDemandSlimNP or NPKDemandSlimNitrogen parameter cPotentialDenitrificationRate.

Important notice

It's important to have accurate organic carbon values for the layers that are within the denitrification depth. If the initial thickness of layers is considerably bigger than the denitrification depth, then the organic carbon in the denitrification area might be higher than the value in the whole layer, as it might be distributed heterogeneously.
