These models must rank cropping systems as a function of weed infestation, and account for variability in effects to estimate probabilities of success or failure. Three case studies are presented: (1) an empirical static single-equation model that directly relates weed biomass to crop management, with few inputs and parameters, (2) a matrix-based multiannual model predicting a few key weed stages annually, from weed control options and a few parameters, (3) a mechanistic process-based multiannual model predicting detailed soil, crop and weed state variables daily, with an individual-based 3D canopy representation, requiring hundreds of inputs and parameters. The chapter concludes that models using a mechanistic representation of the cropping-system ´ environment interactions are best for quantifying effects and their variability, combined with a subsequent transformation with in silico experiments into empirical models of key cropping-system components.","brand":"Dr Nathalie Colbach","offers":[{"title":"Default Title","offer_id":48281320620283,"sku":"9781801464826","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/3917\/9771\/files\/9781801464826.jpg?v=1772487040","url":"https:\/\/indiepubs.com\/products\/modelling-the-effects-of-cropping-systems-on-weed-dynamics-the-trade-off-between-process-analysis-and-decision-support-9781801464826","provider":"IndiePubs","version":"1.0","type":"link"}
