Simulation of the Future based on the History
The new version 6.1.0 of the model includes a new option that allows simple extrapolation into the future based on the previous year. To perform such a simulation we need climate data from a complete […]

GrainFilling Allocation – New option with dynamic allocation rate
During GrainFilling with a change of GSI from 2 to 3. Allocation to Grain is governed by parameters to reallocate from Leaf, Stem and Root. This allocation rate is by a first order parameter for […]
Extended use of Water Uptake functions for each plant
The use of the newly introduced switch WaterUptakeFunction. For the new specific option for each plants now also the temperature impact on the water uptake is considered. In addition the Mass Balance Check for the […]
New version 6.0.2 New developments for Plant Mobile Pool, Water Uptake functions and Litter Fall
The Plant Mobile Pool is active for seasonal reallocation of Nitrogen and Phosphor. The New P model was using a common function to estimate C/P ratios and C/N ratios. However because of problems when the […]
Updated function for estimation of Root Length from Root biomass
Previous version only considered C Root and not C Old Root for estimating the root length. This is now changed so both Fine root pools are considered.
Control of Growth Stage Index after harvest and Growing temp sums
The growth stage funtion is now updated to the post harvest value (GSI Post Harvest) as assigned by the user from the plant behaviour Table During winter regulation of plant The GSI will be assigned […]
Modified Growth Stage Index (GSI) for late ripening stage and reset after harvest
The Last stage of GSI from 3 to 4 according to the scale from full grain filling to a stage of harvest was previously regulated only by a time function. This step has now been […]
Global Warming Potential Variables
The new version is now including optional outputs to compare the global warming potential of greenhouse gas emissions using the conversion factor for CO2 equivalents. The recent factors are based on IPCC recommendation with 28 […]
New options for Sensitivity Analysis – constrain by parameters
MultiRuns with the CoupModel are mostly linked with some type of uncertainty based method to constrain the model outputs based on the agreement between one or more model outputs with corresponding measurements. This is done […]
Re Implementation Heat source as function of decomposition in the soil.
A new parameter called : HeatConversionCoef is defined to estimate the heat source of each soil layer that corresponds to the decomposition of Litter, Litter2 and Humus of each soil layer. The default value is […]
