Resumo:  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 between the tillage treatments were attenuated after establishment of the ley. We conclude that grass/clover periods in organic rotations contribute to a recovery of earthworm populations after disturbance by the plough.
