Summary

Total dosage of copper is maximum 3 kg Cu (2+)/ha/year (metallic copper). If copper preparations are used, the copper soil content has to be analysed each 6th year.

Difference

Copper application is restricted to lower quantities, and if applied the soil copper content has to be determined. EU Regulation 2092/91 Annex II/B IV admits 8 kg/ha of copper (till the end of 2005 and max 6 kg/ha of copper from 2006 onwards (with special rules for perennial crops).

Justification

Copper is being accumulated in the soil: in order to promote soil fertility; any accumulation of heavy metals should be avoided - therefore copper applications are restricted. Standards require the use of preventive measures (crop rotation, crop cultivation, choice of varieties) too.
