ABSTRACT
Humic Acids (HA) and Fulvic Acids (FA) extracted from different peat materials have been characterised by chemical methods. The chemical properties of HA and FA showed differences depending on the source from which they were obtained. Compared with the peat materials, the cation exchangeable capacity (190.20 cmolc kg-1), organic matter (40.83%), total N (2.83%), exchangeable potassium (850 mg kg-1) of Sigirli (S) materials were greater than those of other materials. But Na (28 mg kg-1), Fe (85 mg kg-1), Zn (24 mg kg-1) Cu (4 mg kg-1) and Mn (6.24 mg kg-1) contents of Erzurum (E) material were greater than those of other materials. The chemical properties of HA and FA showed differences depending on source and climatic condition from which they were obtained. Organic C and nitrogen contents of humic acid were greater than FA. Most of the total acidity of humic acid consists of COOH group, but with few exceptions, fulvic acid mainly consists of phenolic-OH.
