public class SimpleRootResidues
extends net.simplace.sim.model.FWSimComponent

Distributes NPK of dead roots to layers, include living roots on harvest.

The component takes daily dead root biomass per layer and adds living roots per layer on harvest.

NPK content of dead and living roots is distributed proportionally to the layers.

Calculation

Total dead root TDR and total living root biomass TLR are calculated from the inputs iDeadRootsRatePerLayer \(DR_i\) and iLivingRootsPerLayer \(LR_i\) \[ TDR = \sum_{i=1}^n DR_i \\ TLR = \sum_{i=1}^n LR_i \]

DeadRootsRatePerLayer \(R_i\) is calculated as:

\[ R_i = \begin{cases} DR_i + LR_i & \text{if } DoHarvest \\ DR_i & \text{else} \end{cases} \]

DeadRootsCRatePerLayer \(RC_i\) is calculated as:

\[ RC_i = \begin{cases} 0.5 \cdot DR_i + 0.5 \cdot LR_i & \text{if } DoHarvest \\ 0.5 \cdot DR_i & \text{else} \end{cases} \]

DeadRootsNRatePerLayer \(RN_i\) is calculated using iDeadRootsNRate \(DRN\) and iLivingRootsN \(LRN\):

\[ RN_i = \begin{cases} DR_i\cdot \frac{DRN}{TDR} + LR_i \cdot \frac{LRN}{TLR} & \text{if } DoHarvest \\ DR_i\cdot \frac{DRN}{TDR} & \text{else} \end{cases} \]

For P and K the P and K dead root rates are calculated accordingly:

\[ RP_i = \begin{cases} DR_i\cdot \frac{DRP}{TDR} + LR_i \cdot \frac{LRK}{TLR} & \text{if } DoHarvest \\ DR_i\cdot \frac{DRP}{TDR} & \text{else} \end{cases} \]

\[ RK_i = \begin{cases} DR_i\cdot \frac{DRK}{TDR} + LR_i \cdot \frac{LRK}{TLR} & \text{if } DoHarvest \\ DR_i\cdot \frac{DRK}{TDR} & \text{else} \end{cases} \]

Notice

The component is sensitive to the order. It has to run after root and plant NPK components, as it takes root biomass and NPK content as inputs.

On the other hand it uses the values also on harvest - when root and NPK components may have reset their states already.

A possible solution to this problem is to use following relative order

1. root and plant NPK components
2. harvest managmenet
3. SimpleRootResidues
