Applicant's summary and conclusion

Conclusions:
The 72hr adsorption/desorption study (OECD 106) on MnCl2 (a more soluble/readily available form of Manganese (Mn2+)) in 35 different soil types illustrate that adsorption is pH sensitive. A median Kd of 994 ml/g was determined for all soil types used (pH range 3.0-8.5
