Summary

Any crop rotation must maintain long-term soil fertility and guarantee prosperous growth. The rotation must minimise the loss of nutrients by erosion or effluent water. A rate of 20% leguminous or soil building crops are required by BIO SUISSE and winter cover of at least 50% of arable land area. Cereals/grain legumes 67%, wheat and others not more than 50% to the rotation. Leguminous soil buildung crops must cover at least 25% of the share in the rotation. A break of at least one vegetation cycle is required before a crop of the same family shall be planted again.

Difference

Whereas BIO SUISSE regulates the crop rotation requirements in detail, the EU Regulation 2092/91 is more general in this area.

Justification

A balanced and sophisticated crop rotation is crucial to maintain long term soil fertility, to enhance natural nitrogen level and humus accumulation. Therefore clear requirements are necessary to support this aim.
