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

Calculates P leaching, plant availability and uptake and transition between dissolved, active and fixed phosphorus.

Calculation

For details see also SlimPhosphorusFunctions (link to its documentation below the variables table).

On initialisation

• Initializes pools by calculating amounts from concentration (AmountFromConcentration()).
• Calculates coefficients for the flows (CalculateFlowCoefficients()), depending on the soil type.

Daily calculation

• Adds mineralisation (from input) and fertilizer to dissolved P.
• Calculates interchange between dissolved, active and fixed pool (PoolsInterchange()).
• Calculates leaching (Leaching()).
• Calculates plant available P and peforms the uptake (Avail() and Uptake()).
• Calculates rates, states, P balance and concentrations from amounts (ConcentrationFromAmount()).
