| The CEC increased from 32.5 to 65.6 cmol kg-1 indicating humified organic material. |
| In this work, the term 'humus' refers to the extractable and non-extractable soil organic humified matter, which includes humic and fulvic acids and humin. |
| Localized areas of humified peat and moss also occur, and more than 200 hectares of peat bog exist in the protected water area. |
| Detailed analysis of bound atrazine residues in soil demonstrated that most of the residues were in the finest soil fraction that contained humified organic matter. |
