Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Guideline:
- other: no data
- Deviations:
- not specified
- GLP compliance:
- not specified
- Type of study / information:
- Struvite was assessed for safety under Dutch regulations. Struvite did not exceed Dutch regulations for heavy metals or pathogens. Struvite had similar effectiveness to soluble fertilizer. 200 kg P2O5/ha of Struvite improved maize performance.

Results and discussion
Applicant's summary and conclusion
- Conclusions:
- Both Struvites were within the limits for heavy metals and pathogens according to Dutch regulation.
Plant availability from Struvite is comparable to soluble phosphate fertilizer.
Struvite is a safe and effective p fertilizer. - Executive summary:
Both Struvites were within the limits for heavy metals and pathogens according to Dutch regulation. Plant availability from Struvite is comparable to soluble phosphate fertilizer. Struvite is a safe and effective p fertilizer.
