| A key challenge in organic agriculture is the reduction of tillage intensity. While previous research has shown earthworms to benefit from reduced tillage (RT), little is known about after-effects of RT during the grass/clover ley phase in organic rotations. In a large-scale replicated on-farm trial in England we studied earthworm populations before and during the ley phase, comparing the Ecodyn cultivator (tilling depth: 7.5 cm) with a mouldboard plough (depth: 15 cm). Spring sampling of earthworms during the ley phase revealed no significant difference in earthworm densities between the two tillage treatments while two years earlier in the arable phase, earthworm densities had been significantly higher under RT. Also, differences in species composition... |

| Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time. |
