How to model crop-weed competition for soil resources: Connecting the STICS soil submodel to the FLORSYS weed dynamics model
International audience
Integrating plant-plant competition for nitrogen in a 3d individual-based model simulating the effects of cropping systems on weed dynamics
International audience; Promoting biological weed regulation by shifting resourceavailability and use from weed to crop may providean option for a more sustainable weed management.Light is generally the main resource for whichcrops and weeds compete in conventional croppingsystems. But, with the necessity to reduce mineral nitrogenfertilizer use, better managing crop-weed competitionfor nitrogen may become crucial. However, itrequires better understanding the functioning of heterogeneouscanopies in nitrogen-deficient situations. Simulationmodels are powerful tools to reach this goal.Our objective was to integrate plant-plant competitionfor nitrogen into the FlorSys model, already simulating…
