Crop Rotation AnalysisRequirement Current state
Crop model: AGROTOOL:
Generic simulator
Versatile algorithm for all maintained cultures. Calibrated models for cereals (summer and winter wheat, winter rye, barley, oats), maize, potato, root vegetables, annual and perennial forages, legumes.
«Wintering» Continuous calculation. Modified descriptions of snow melting and soil thermal regime.
Predecessor influence
Separated calculation of litter and root residues in the module of carbon-nitrogen transfer and transformation in soil. Sub-model of symbiotic nitrogen fixation and nodule nitrogen dynamics.
Simulation infrastructure: APEX:
Multiple runningValidated and implemented integrated environment for
multivariate analysis and automation of computer experiments with crop models.
Crop rotation supportSpecial plug-in for planning not full factorial experiments
and performing complex serial-parallel schemes of scenario computation.
Forecasting Built-in stochastic generator of daily weather variables that takes into account possible climate changes.
«Inherited» model variables:
Shoot litter (aboveground biomass)Root litter (belowground biomass)
