In-field development of a conceptual crop functioning and management model: A ca

The biophysical system is composed of a more or less complex set of compartments (cultivated  plants, soil, weeds, diseases, pests), with each being represented by one or several state variables. The technical system is a combination of cropping techniques which act individually or interactively on the size of a compartment, on its state variables  or on flow between compartments. For each field, the cropping interventions were recorded: manure application, soil tillage, sowing date, herbicide applications, weeding operations, mineral fertilization, insecticide operations
