- Conclusions:
- From the experimental data obtained according to CIPAC method MT 59 and OECD guideline No. 110, it can be concluded that, after 5 minutes of shaking, over 93 % of the sample of Algea Fert Solid K+ presents a particle size higher than 0.250 mm and no sample of Algea Fert Solid K+ was found under the 0.045 mm sieve.
