public class AMPSomAuxiliary extends net.simplace.sim.model.FWSimComponent
Auxiliary component that acts as a bridge between AMPSom and other SimComponents like SlimRoots, SlimWater and SoilCN

The component provides to AMPSom

  • root exudates per layer
  • vertical flow of dissolved organic matter (DOM)
  • C and N from litter that enters the dissolved and particle organic matter pools in upper layers

by using

  • daily increment of root biomass from Biomass component (e.g. Lintul5)
  • root weight per layer from a root model (e.g. SlimRoots)
  • water content and percolating water from a soil water model (e.g. SlimWater, Hillflow1D)
  • daily change rates of metabolic an lignocellulotic and cellulotic C and N of the litter from a litter decomposition model (e.g. SoilCN)

Root Exudates

Root exudates are calculated as a fraction of the daily root biomass increment. C and N content of exudates are calculated by ratios provided by the user. The exudates are distributed to the layers proportionally to the root biomass per layer.

\[ ExudatesPerLayer_i = iRWRT \cdot cExudateFraction \cdot \frac{iRootBiomassPerLayer_i}{\sum_{j=n}^{NL} iRootBiomassPerLayer_j}\\ ExudatesCPerLayer_i = \frac{ExudatesPerLayer_i }{cBMCRatio} \\ ExudatesNPerLayer_i = \frac{ExudatesCPerLayer_i}{cCNRatio} \]

C and N from Litter

The inputs from SoilCN are converted from kg/ha to g/m^2 and assigned to the different litter pools

  • CDomRateFromLitter = iSoilCNExtract1 + iSoilCNExtract2
  • NDomRateFromLitter = iSoilCNLmtsu
  • CPomRateFromLitter = iSoilCNCellose1 + iSoilCNCellose2 + iSoilCNLigncellose2 + iSoilCNLigncellose3
  • NPomRateFromLitter = iSoilCNLstsu + Llisu

Vertical movement of dissolved organic matter

There is a simplistic approach to calculate the vertical movement of dissolved organic matter from a layer to the adjacent ones. It considers the concentration in a layer and the water that moves in / out from that layer. Positive water flow values mean that water is flowing from a layer to its lower neighbour. Negative water flow means that water from the lower neighbour is flowing into the layer.

Concentrations per layer are calculated from previous day's water and dissolved organic matter content. Then the concentration is multiplied with the vertical water change rates and the amount is added / subtracted to/from the layer the water flows in / out.

With higher amount of rainfall, there will be more water flowing from one layer to the next one than the capacity of the layer. This may wash out the dissolved C and N completely. However, the user can set the cVerticalFlowFraction to limit the amount of dissolved organic matter that goes from one layer to the next.
