For those converting, and for policy makers, it is important to know whether plant yield changes with the duration of organic management and whether other aspects of organic management (e. g. weed abundance or enhanced weed diversity) increase over time. In order to test this, we compared maize yield on 34 farms: 9 conventional farms, 9 farms which recently converted to organic farming as well as 16 farms which were managed organically for 9-32 years. We also determined the number and abundance of weed species in each field. Maize yield was not affected by the duration of organic management, although N input was approximately 35 % lower on... |
