| Organic farming is popular, and an increasing number of conventional farmers consider to convert to organic farming. 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... |

| One of the primary challenges of our time is develop sustainable farming systems that can feed the world with minimal environmental impact. Some studies argue that organic farming systems are best because these have minimal impact on the environment and are positive for biodiversity. Others argue that no-tillage systems are better because such systems save energy and preserve soil structure and quality. A third group argues that conventional farming systems are best because yield per hectare is highest. However, so far, systematic comparisons of major arable production systems are rare and often it is difficult to compare the advantages and disadvantages of farming systems in a systematic way due to differences in soil/site characteristics and management.... |
