Corn stover ploughing-under influenced significatly only the yield of Italian ryegrass in the second year trial. Moreover the reduction on the nitrogen leaching was influenced by corn stover ploughing-under, but in this case the effect was particularly evident in the first year trial during wheat growth. This fact determined consequently an increase of the
