Applicant's summary and conclusion

Conclusions:
Given the scale, the coverage of all EU countries and the recent date of the study, the results are considered relevant for assessing current soil quallity (grassland) in the EU.
Executive summary:

90P zinc concentrations for 3 EU countries are given in results section. The remaining 24 country data are given in a separate study record.
