Identification of sustainable cropping systems with high multi-sector performances
2014
International audience; Multicriteria assessment is needed to identify promising cropping systems with good performances on different components of sustainability. Some trade-offs between criteria may occur. A better knowledge about the relationship between criteria can help (i) to ide ntify cropping systems with high multi-sector performances (e.g. Castoldi et al., 2010; Firbank et al., 2013), and (ii) to guide policy makers’choices. In this paper, we present the early results from our multi-sector evaluation performed on data collected on cropping systems experiments.
Herbicide site specific spraying: use of simulations to study the impact of section width
2019
International audience; Site specific spraying is one way to reduce the amount of herbicide required to control weeds. The impact of boom section width was investigated by using simulated weed infestation maps with various weed coverage rates. Herbicide applications were simulated combining these virtual maps with various boom sections widths and various theoretical spray patterns. The objective was to quantify the herbicide reduction possibilities and potential under-application areas. Simulation derived results are analyzed using three indicators: i) the ratio between herbicide amount in the case of a targeted application and the amount deposited in the case of a full application, ii) the…
Tracking Ideal Varieties and Cropping Techniques for Agroecological Weed Management: A Simulation-Based Study on Pea.
2022
Book of abstract p.110-111; International audience; Pea (Pisum sativum L.) is a key diversification crop but current varieties are not verycompetitive against weeds. The objective of this study was to identify, depending on the typeof cropping system and weed flora, (1) the key pea parameters that drive crop production,weed control and weed contribution to biodiversity, (2) optimal combinations of peaparameter values and crop-management techniques to maximise these goals. For this, virtualexperiments were run, using FLORSYS, a mechanistic simulation model (Colbach et al., 2021,Field Crops Res 261:108006). This individual-based 3D model simulates daily crop-weed seedand plant dynamics over t…
