From: Comparing crop rotations between organic and conventional farming
Average ( ± standard error of the mean) rotation length [in years], total number of crop categories in organic (green), and conventional (orange) rotations and land-use, as well as the Shannon Index (H) and the Equitability Index (EH) calculated at the global scale and by global region using the rotation and the land-use datasets. H and EH are calculated based on the timeshare of each crop in the rotation (for the rotation dataset), or based on the relative harvested area of each crop category (for the land-use dataset). The total number of crop categories considered was n = 11 in the rotation dataset and n = 6 in the land-use dataset. **P < 0.01; *P < 0.05; †P < 0.1.
