Summary

Organic farmers are encouraged to adopt conservation tillage to preserve soil quality and fertility and prevent erosion. In the framework of a national study, we compared conservation (no tillage NT and reduced tillage RT) and conventional (mouldboard ploughing MP and shallow mouldboard ploughing SMP) tillage systems in 3 field experiments and 2 on-farm surveys. We measured the impacts of soil tillage on: (1) soil compaction: more compacted soil under NT and RT, (2) earthworm populations: more earthworms under NT, (3) weed infestation: weed level tends to be higher under NT, but it is not a general trend, and (4) crops: crop yields are lower under NT according to weed infestation. Then, independent of soil type and experimental year (2 to 5 years), it seems that soil physical fertility decreases under NT and RT. But, the first reason of a decline of crop yield under NT is the weed infestation.
