Selection criteria 

The main criteria that led to the exclusion of a synthesis paper were if the paper: (1) does not deal with crop rotation; (2) does not include results for cropland (e.g. pastures, forests); (3) deals with cover or break crops; (4) experimental treatment included other practices as well (e.g. tillage); (5) did not consider direct side-by-side comparisons; (6) is a non-systematic review or a non-quantitative systematic review. 

Synthesis papers that passed the relevance criteria were subject to critical appraisal carried out on a paper-by-paper basis. The search returned 243 synthesis papers potentially relevant for the practice object of our fiche. Searches for other farming practices added another 5 potentially relevant synthesis papers. From the 248 potentially relevant synthesis papers, 199 were excluded after reading the title and abstract, and 32 after reading the full text according to the above-mentioned criteria. Finally, 17 synthesis papers were selected for crop rotation.
