Leys from a Nordic perspective : a knowledge compilation

The project involved creating a popular scientific review of the cultivation and use of leys for livestock. Target groups are the agricultural sector and industry. The project had four work packages (WP): crop production, harvest and conservation, feed value for different animals, and economy. Within each work package, search strings were developed and inclusion criteria defined, and a database for each WP developed through searching in online databases. Each selected article was assessed first on the title (include or exclude), second based on reading the abstract, and third based on reading the article. The review provides an extensive list of literature related to ley production and use, a description of the most important findings, and suggestions for future research.
