Results and discussion

Applicant's summary and conclusion

Conclusions:
No risk is expected for non target micro-organisms.
Executive summary:

A validated study on the effects of Phostoxin (56% AlP) on the activity of the soil microflora is mentioned.

The nitrification activity was inhibited for a fortnight and the dehydrogenasis activity was reduced by approx 29% in one of the tested soils. Both effects were reversible. Overall, it was concluded that no risk was expected for non target micro-organisms.
