- •
The effects of tillage and crop sequence on soil N availability and N efficiency indices were evaluated.
- •
No tillage (NT) can ensure equivalent or even higher yields than conventional tillage (CT) as long as it is accompanied by a rational crop sequence.
- •
Compared to CT, NT leads to reductions in both native soil mineral N and N-fertilizer recovery.
- •
Reductions in soil N availability under NT were more evident in continuous wheat than in wheat grown after a legume crop.
