A. Romani, P. Pinelli, V. Moschini, D. Heimler


Using a long term experiment (20 and 11 years of organic cultivation on the same soil), sunflower was cultivated on these soils under organic management and in a different part of the same farm under conventional management.

No qualitative differences were found in the three cases, while quantitative differences have been pointed out and discussed.
